LAMH Look At My Hair and Iray Tutorial

Can someone make an up to date guide on the Look At My Hair product built into Daz3d. LAMH behaves differently when used with Iray vs 3Delight. The webpage: http://www.furrythings.com/ tutorials on youtube and PDF by the creator are old and I wish they where a bit more user friendly. LAMH is a powerful tool and many of the figures include hair/fur applyed with this product. I use Nvidia Iray so It never shows in the Render preview or in render. I'm sure there's some trick to it that I'm just not understanding. I also know you can create your own hair/fur and what not with this product as well. I do have the 3 listed products below.
Look at my Hair FREE Player (included with Daz3d)
LAMH 2 Iray Catalyzer
Here are two fantastic Daz artists that make great LAMH figures: RawArt & Alessandro AM
Well as always Thank you for your time and assistance!
Sincerely,
Jacob
Side note: I have lot's of models with LAMH such as Cat World for Genesis 8 Male(s) Cat World Regenesis HD - Bundle Street Rat - The Rat Man Gorilla for Genesis 8 Male Monster Classics - The BeastMan and some others That I may have missed.

You are this close to answering your own question. LAMH is for 3DL rendering and it is not recommended to have the free player and the full version installed at the same time.
For Iray, you must use the LAMH2 Iray Catalyzer. There is a special Render button on the plugin's GUI that must be used. It will only work with Iray Catalyzer presets, not with the regular LAMH presets. There is no preview available for Iray Catalyzer, only full renders.
Catalyzer, if available, is the simplest solution but it supports only the vendor's own sets. For your own hairs, if you have the full vresion of LaMH, you need to export as OBJ in the final pose.
I export them as Fiberhair although you can't then change the pose.
That's still OBJ, though, as I recall.
This is why I'd REAAAAAAAALY like an updated tutorial I get confused by the older out dated material. While relivant it uses a much older version of daz studio when used in the explainations. I don't suppose anyone would be willing to do a Live stream or something. Some tutoring on this one would be really helpful. I'm currently going though the chain of youtube vids by the creator and reading the pdf provided 1.5version. But I always get confused especially when transfering between the LAMH with the product fiberMesh (or object file) how to save it etc. It always seems to want to overwrite some other files and im worried I'm going to screw something from the orginal model up.
When I look under daz Help menu-->about pluggins it only lists: Look At My Hair & LAMH2Iray Catalyzer so I assume I replaced the "free" version a long time ago during install. I just initally listed it above for information purposes without thinking. I like to try to give people as much information as possible about the subject that I know of to help find a quicker solution and give people a chance to find more of a product they take interest in as well.
Also AFTER you make it an object/fibermesh can people later on add bones/rigging (is that the word?) to the hair so it can move/be adjusted later on?
Mmm, well, there is, just not within DS unfortunately.
I don't want to get your hopes up as I'm using another app, with custom tools that I don't think are developed for anything else, and another set of tools where the author has gone MIA with orders piling up.
But essentially I export as FBX. Depending on the figure, there may be some morph baking work & rig alterations. With Fur, I've a tool that will apply weight mapping correctly to the fur geom. This can really balloon up the object size. Where there's an All Body fur group, I'll divide that group into 4 or 5 sections.
The resulting fur can be animated with bone deformation, but won't respond to morphs.
Here's a recent example with the Snow Leopard. He ended up with 8 fur sections:
Yes in D/S one can rig any .obj file including one for hair. Same concept as rigging for clothing just scroll down the list for the hair option.
Morphing can be more the challenge as Hexagon can seldom handle large hair .obj files - Zbrush or some such program would do a better job.
OMG He's so cute! Don't worry I'm no where near ready to do any of this more advanced stuff so no delusions or false hope, But I do Dream and Aspire to reach for it! I only know daz studio at this time, no hex, zbrush etc at this time... lol I'm still struggling with lighting. I'm just trying to learn the basics of each function so I can fiddle with it and maybe make something cool via happy ending and eventually on purpose. So jelly. Here's my hack attempt at a mane (Description of how I did it on the side pannel) I was hoping to make a G3 and G8 version for cat world regenesis out of LAMH but It just might be something out of my dept at this time. My King My Queen
So what can I do if I have unknowingly installed both? (The version of DAZ Studio I use is 4.12.0.86 Pro Edition.) Currently everytime I start DAZ Studio I get this message saying "Warning: both the Look At My Hair player and full libraries are installed." Basically I just want to do some 3DL renders using RawArt's Beastman and Sasquatch. Both of them are supposed to have LAMH presets but currently when I try to load those LAMH presets I get this further message:
"The following files could not be found:
data/daz 3d/genesis/base/morphs/daz 3d/freak 5/fbmfreak5.dsf"
And you guessed it: the presets could not be loaded (sigh). Do you actually need freak 5 to be able to use the said presets, surely not? In the early days I could load the LAMH presets easily, and as far as I remember I never bought and used Freak 5. Why this strange change?
I'd be most grateful if anyone could help with my above queries. Thanks in advance. Can the IRAY Catalyzer currently handle the LAMH presets for the Beastman and Sasquatch, by the way?
No, only 3Delight.
They can render in Iray if exported as OBJ and reimported, assuming you have the LaMH plug-in to do so. Catalyser is a convenience tool rather than the only way to get there.
Only AM knows how to convert LAMH hair to Catalyzer, so only his creatures (and, if I'm not mistaken, not even all of them) come with Catalyzer presets.
To be honest, the whole thing is rather frustrating. LAMH is presented as an easy way to edit and comb hair in DS. It is not shown as a tool for a workaround that may or may not work involving import and export. The material changes would cost some time.
On a somewhat separate note, the Orangutan Hair is so long (and the Catalyzer plugin can't shorten it) that it leads people to think that maybe the full version LAMH can control it easily... But then they discover the above-mentioned problem.
Meanwhile, the chimp's hair works perfectly fine because it starts at a short length.
To sum up, some of the inconsistencies cause unneeded hardships for the customers that an updated manual could fix?
You can shorten the orangutan's fur if you use the dForce version of the hair rather than LAMH/Catalyzer by altering any or all of certain parameters in the surfaces pane.
The pane default is 100 for shorter hair. It can not go any lower than 100. Therefore, it can't go shorter than the default 100. It is a bit disappointing.
Alas, Gordig, can you please show me how, if it is possible?
Gordig, please excuse me. Finally, I understand what you are saying. I do not want to start a circle argument.
However, I am looking for an easier way than trial n error with dforce hair. The slider is the easier way, but it doesn't work in that direction which kind of defeats its whole purpose.
I accept this limitation but do not agree with it.
Thank you for your help and illumination.
That panel has no purpose if you use the dforce hair like Gordig suggested
I purchased and installed the latest version of LAMH and it is not showing up anywhwere. I have Allessandros_AM Red fox and want to apply a preset, but without LAMH not being loaded it has no hair.
Insall Manager shows it as being installed.
Also under the Help menu I believe you can find and input the serial number there (if you haven't already during install).
Along the top menues select WlNDOWS--> PANES (TABS)--> I think it will say LAMH (full version is at 1.06 on website) with a little face icon. drag and drop that window onto whichever side so it becomes a tab and now you will have access to the LAMH window once inside It should have an editor button. Good luck reading the PDF which you should beable to get from: https://www.furrythings.com/ ; https://www.furrythings.com/LAMH1.5/LAMH.manual.1.5.zip
-Here's some other useful links of his https://www.youtube.com/user/mastronardialex
Tips: LAMH does NOT show for the Nvidia Engine Render till the end and only if you save it as a Render (obj) it's wierd process but general idea is pose and set your figure/scene till your ready for final render then you set the LAMH as an object and THEN you render upon which you will see it.
It Can be seen, edited and rended in 3Delight as to my understanding the exception to this is an alternate product produced by him called https://www.daz3d.com/lamh-2-iray-catalyzer
BUT it will ONLY work with HIS ANIMALS that HE MAKES the FUR for which he makes avalible on the www.furrythings.com website for free ( I think).
I hope this helps answer your question(s). The ReadMe and pdf 1.05 come in the file folder of the LAMH program that are installed I believe.
Sincerely,
Jacob
That is my exact point!
There are too many caveats with LAMH. If trimming hair before using it for dforce or the catalyzer is not possible with a program with a comb it is like buying a bike without pedals. I hope you get my point without me having to spell it out anymore. I know this sounds snarly, but I am not, I am only clarifying and appreciate everyone's opinions and feelings.
LAMH and dForce hair are totally unrelated, they're different systems. I don't see why you would expect to use LAMH to style dForce hair.
