That would be utterly awesome, Allessandro.
I look forward to this as well Alex!
Let me see if in the next days I can make a tutorial that covers all the process of furring a model. There is one with a mammoth, but it was done with the LAMH WIP version (1.0 alpha), and controls have changed pretty much since then.Same her, as posted above. I look forward to the how-to from start to render. Especially if it includes a few subtle reminders of Ctrl-click this or Shift-click that (some tutorials somewhere excluded that, resulting in me not being able to follow them at all).
LAMH is on my shopping list as I have projects where I know it's going to be useful. I like the idea of a tutorial, but, I'd like one in .PDF format as I tend to find video tutorials somewhat laborious. Particularly when you want to concentrate on one bit and have to keep pausing the video and never quite getting back to the same bit and you have to keep switching between full screen and normal to minimise the window so you can go back to DS if you have it open. A PDF is much easier to follow and you can easily switch between Reader and DS.
Just my thoughts, you can do what you want...
CHEERS!
I think I will be 'forced' to make a video tutorial (and a long one, since it will have to cover a lot of operations and topics). I honestly don't think I will have the energies to make a .PDF with screenshots out of it.
As someone who has also found LAMH a little hard to grasp, some of my basic tips:
For head hair, I like to start with Genesis Hair Cap -- if I make hair for that, I can fit it to a wide range of figures. Also, it's fairly easy to select a reasonable amount of facets to do what I want.
Follicles: click the first to 'add all facets.'
Styling: First bit generates hairs with the rightmost button. You can change the length and control points (sort of the 'resolution') of the hairs here, I usually just leave it alone. If the hair goes a way you don't like, just click the button again to reset everything.
There is no 'undo the last thing I did' in LAMH, which is unfortunate.
Taper is a great way to quickly/easily trim up the hair in the back, where it's useful.
Spherize basically 'pulls' the hair along a certain axis. Note that many of the styling functions have different axes you can select, and you can select multiple ones at a time.
Swirl is good for a lot of hair, basically pulling the hair in a spiral. Careful use of taper, spherize, and swirl can capture a lot of basic short hairstyles.
Nearly all of the hair I've been able to generate uses these styling functions, with little-to-no actually 'combing' or 'scissors.'
The Curl function does mostly what it says, though the curls are all over the place. Using the hair in Iray, I've only found Curl useful if I can spare increasing the resolution of the hair. Otherwise the 'curls' look very angular and fake. I'd avoid using curl much unless you have a really beefy computer (or you aren't using Iray).
There's a little Eye icon about halfway through the panel. The green lines to the left show guide hairs. Clicking the Eye icon turns on what the rest of the hair will (probably) look like, which is important with the next bit of styling, because the actual hair will diverge from guides.
Random roots, I think, moves around where hairs will come from. I'd keep this maximized.
Random length: a little of this can keep hair from looking too fake. Too much, though, and it looks like someone has really unkempt hair.
Clump hair is good for 'bunching' the hair, almost feathering it, or maybe wet hair.
Frizz hair can give hair a bit more realism. I'd play with it, and I like to give all hair at least a little to give it some life.
The final thing is 3D paint. It's a little weird to use, but my recommendation:
Holding down shift makes it an eraser, while otherwise it paints solid. I'd shift-paint the edges of what you want to work for, then save the map and go look for it in LAMH presets folder.
Then copy the image and work with it in your favorite image editor for more fine control.
I haven't used 3D paint a huge amount, but the most important use of it is to paint a more natural-looking hairline (that doesn't require a lot of scissor work).
FINALLY... I use comb and scissors only to clean up the edges. Sometimes the functions will leave weird swoops of hair over the forehead, so trimming or moving those back might be a good idea. Also, significantly, cleaning up hair around the ears, so they don't clip through badly.
Hope that helps someone!
Actually there are undo's and redo's...
Thanks for those tips timmins, I like what you've been able to produce and your work started my drive to really learn how to do this.
Oh hey, so there are. I missed it because the button placement suggests they have something to do with size or whatever, and because the normal keyboard shortcuts don't work.
Ok, undo/redo buttons are in the upper left corner, the curved arrows.
I hope this is the correct thread for this type of question, if not please refer me to the correct one.
First thing first: I currently do not own the full version of the LAMH-plugin, but use the free player version. (I am planning to get the full version, but, as a Poser user, it's hard to justify the purchase of a plugin for DAZ studio (I pretty much only use DAZ studio for Allessandros animals));
However, I own five of Alessandro_AM's products with LAMH-presets and will definitely get them all at one point.
Now to my questions: I am struggling with the OBJ-export feature of the LAMH player and I guess I am doing something wrong. Currently I am only trying to export the basic fur presets to OBJ and get Poser (and Reality/luxrender) to render them. My first problem is, that during export DAZ studio uses an unreasonable amount of RAM.
For example, if I load the LAMH-Moose-Male figure from the library, open up the LAMH pane and click "ToOBJ", the obj export works, but at some point, DS/LAMH eats up ALL of my 16gb RAM and even starts swapping. While I am aware that the hair geometry will need lots of RAM, >14gb during export still seems pretty excessive to me (Of course, RAM usage decreases when I decrease the number of hairs, but I read somewhere in this thread that one million is pretty much the lowest acceptable setting, if you want good results).
The resulting obj-file has a acceptable size (between 1 and 2 gb, depending on the hair count), but my (64bit) Poser still struggles during import: if I import it, most of the time nothing happens at all, the statusbar stays at 0 even after waiting for >10minutes. Interestingly Poser's RAM usage doesnot change at all, so I guess Poser isnt doing anything except showing the import dialog box. I had somewhat better luck with PhilCs obj-import plugin: it was able to load the fur obj but Poser froze directly after the import.
The only time I successfully imported a fur-obj to Poser was a test export with a very low hair quantity (I think ~50000) and while the import worked well, it didnt look very good and I struggled to match the scale of the fur and the actual figure (although I told Poser not to scale the obj during import).
So, what do you guy think? Am I doing something wrong? Is my PC too weak? (AMD FX8350, 16GB RAM, Geforce GTX550Ti; Poser and DS are installed on a SSD) Or am I just missing something?
I saw screenshots where people showed their settings for obj export (page 53 of this thread), and I couldnt find these options anywhere. The only settings I can see are the basic ones from the LAMH panel (complexity, Hair quantity, Thickness Root/Tip etc). Do I need the full version of LAMH to get advanced OBJ export options or am I missing a button?
Thanks very much in advance, everyone!
I think I will be 'forced' to make a video tutorial (and a long one, since it will have to cover a lot of operations and topics). I honestly don't think I will have the energies to make a .PDF with screenshots out of it.
Fair enough, I'll have this thread to refer to now.
CHEERS!
Hello, yes this is the correct thread for support: if you like, you can also email me directly at 'info@alessandromastronardi.com'. I'll try to help the best I can.
About the export to OBJ, the file size and the memory consumption during the process can be massive. The moose, specifically, comes with a 1.5 million hair count fur, which is really a large amount of data when it comes to OBJ export.
I tried on my machine with a 1.0 million, and at some point the memory usage was around 13GB: no doubt that you can easily exceed that limit using 1.5 million hair.
If I were you I'd try exporting 800,000 - 1M hair, maybe increasing root and width to 650 and 200 respectively.
After the OBJ export is done, and the mesh is visible in Studio, I usually export the whole scene (thus both model and fur geometry) to OBJ, collecting the textures (that's in the export options dialog), so that I have all I need in one OBJ file.
I was able to import and render the moose in Poser: just a note, in the Poser import dialog make sure to disable 'Make polygon normals consistent', otherwise Poser will recompute all the normals and take 3x the time needed to complete the import.
If you are planning to use large geometries, probably adding another 16GB of RAM would really help your system.
I hope this helps.
Thanks Alessandro, yes that helped a lot. I think the problem which caused Poser to freeze during import really was, that I didnt deactivate "make polygon normals consistent". I was pretty sure, that I tried to deactivate all of Poser's import options, but I guess I have missed one, sorry. After that I could import the mesh in Poser (even with 1.5mio hairs). It needed some time, but it imported :) Poser used around 8GB RAM after the import, but it had to swap when I tried exporting it via Reality to Luxrender. The export took a while, but succeded in the end, so using 1.5mio hairs is definitely possible with 16gb RAM, but it involves some waiting time. Luxrender needed ~5gb during rendering so thats absolutely within limits. Also it rendered astonishingly fast, I was really impressed, so who cares about some waiting time during export ;)
I will definitely try your suggestion to use 800k-1M hair with the thickness you suggested. Up until now, I left the thickness-settings at their default values, but IMO it already looked pretty good in my test render
Thanks again, you were very helpful! And I'm happy that I can now use these pretty LAMH-furs within Poser :)
I seem to remember that Guillaume Hair, which is considerably less complex than anything in LAMH, just refused to even load in Poser, mind you, I did only have 4gb of RAM at the time. I have 16gb of RAM in this machine, so, I don't think I'll be doing much import export and will stick to DS.
CHEERS!
Bug in 4.8 (maybe 4.7, too, I haven't tested):
If you attempt to apply a LAMH preset to a G2F that is in a group, client will crash. (It might apply to other figures, haven't tested)
Bug in 4.8, at least:
Created a LAMH item with a density map. Open it up later, attempt to update the density map, 100% crash when hitting 'update materials and exit'
I love LAMH, but it's one of the buggiest things I've used in a long time.
Yes there are at least a dozen major issues that we are trying to address. The crash on editing items in groups, that you mentioned in your earlier post, is one of those. This one that you mentioned about density maps, it happens sporadically for some users. If you are able to reproduce it, and email me the DS and LAMH log files at 'info@alessandromastronardi.com', it would help us to pinpoint the issue.
first, i want to say because this often gets overlooked, but... the mesh size of a hair strand in obj format is larger than the LAMH renderman curve. Exponentially larger. i usually can cut the hair amount in half, or even by 3rds, when exporting to obj. And besides the hair count, you can choose the resolution to export the hair at- low resolution for short fur works great- for long human hair though you'd want a high resolution of hair (but thankfully, much lower hair count). finding a balance between the strand size, the strand count, and the mesh resolution will help with your export. It should be possible for your scene to hold a great deal of object fur... one of my favorite scenes i did with LAMH, attached... the grass was made with LAMH, and exported as obj. Girl's ear/tail fur is LAMH, exported as obj. Her hair is also LAMH, exported as obj. And the squirrel fur also exported to obj. I don't usually do that, but i wanted to test the limits. :) And i used the wonderous dynamic dress too, on genesis...
Anyway you can see there's quite a lot of stuff and it came out pretty well.
Question
Is there a way to mirror one hair group to the other side?
Say you have a hair style that's parted in the middle and don't want to try to recreate that sector evenly on the other side of the models head ... is there a way to select that group and tell the script to mirror to other side??
Thanks!
Hello Richard, if the model is symmetrical and in 0 pose, you can mirror left to right side (or viceversa). Hover on the buttons labelled "LR" and "RL"...
Thank you for the info Alex! :-)
BTW, if you want to make short afro-like (or very curly) hair, you don't have to do much than select appropriate facets and use Frizz ends until it curls up enough.
(I highly recommend playing with density maps)
Hello,
I am somewhat new to DAZ and really enjoy some of the options. I installed the LAMH free player but have not used it because I don't see any where to start up the LAMH program. This may be because my DAZ content folders are in my F drive whereas the LAMH player installed onto my C drive. I thought about simply moving the folders over to my DAZ folders in the F drive but I am not sure where to exactly place the folders so that the program will work correctly.
I hope someone can help me get this working because I have seen some really great renders with LAMH in use.
Thank you,
Bruce
Hi Bruce, if you don't have a Create->Attach LAMH Object menu item, then the plugin may not be installed correctly. If you use the DAZ Install manager application, you can eventually reinstall it again easily.
I do have that! But when I click on it there are no presets listed.
So, how do I create presets?
To create presets, you need the full (commercial) version.
Speaking of presets, where should we donate them? :)
You can email them to me at 'info@alessandromastronardi.com' , with a preview render, and I will be happy to make them available through www.furrythings.com, and make a post on both LAMH FB and blog crediting you as deserved. Thanks
I need the full commercial version to create presets, but are there presets available for free from www,furrythings.com?
Yes, sorry if I didn't mention this earlier. At these links you got free presets for most common figures:
http://www.furrythings.com/presets-humanoids/
http://www.furrythings.com/presets-animals/
And of course there are several LAMH based characters available in the DAZ Store.
