Hello,
I just purchased the LAMH product. It look snice with standard DAZ renders but I use Octane and its the reason I bought the LAMH product.
When I either open the Viewport for Octane plug in or Export the Black panther as an OBJ the hair is not showing at all.
Is there a workflow or a setting that I need to do to get Octane to render this? Do I have to use Standalone Octane?
Thanks

You are lucky it does not crash
Octane does not render LAMH as it is Renderman curves which the Renderman compliant 3Delight renders, for other renderers or export you need to export it as an obj, the free player will even do this, it is very high poly though.
hey there i did export as OBJ, imported into octane stand alone.
Do you mean i cant use the presets that the panther has in DAZ, i need to make new hair in LAMH and export from there into DAZ/Octane?
Im a bit confused by the work flow
I wish they would mention this in the promo to me this should be fairly easy or standard if your going to promote it for my money
Can some one list teh workflow for this, I hope its not Zbrush lite work flow, I have Zbrush... I though this would be easier as a plug in with DAZ
You did not mention you exported an obj from it
yes you can any LAMH but the panther would be a very heavy resource hog and possibly rather fine hair, you may need thickness added making it even more highpoly
I have indeed done it but gotten rather wiry hair as had to reduce the amount of hair as well as add thickness for my computer to cope.
Head hair props are considerably easier than fur.
So what I did was export from DAZ as OBJ / collect maps etc.. when i import into Octane no fur no nothing... I am missign something I am sure of it.
Is simply loading the LAMH option in DAZ then exporting the right work flow?
Or do I need to make new hair in teh plug in then export / import that?
Will the Octane plug in work with it?
thanks!

before you ask I must add
it was a lot of work and swearing to rig the fur with transfer utility though manually filling weights by surface areas to stop fur vertex stretching
I had to work in bounding box mostly to avoid crashing to desktop rigging it!
it does load and render easily though once saved as a support asset which also is crash prone.
Now I see you tried exporting a LAMH scene as an obj
no
you use the LAMH player or full window under edit windows to do it in studio
I have another question, I select the panther in DAZ, click on Create, New LAMH OBJ, LAMH UI pops up empty, when I click import with BigCAt selected I have a blue empty screen.
Secret to getting the cat to show?
This seems like a waste of $ ATM.... :(
Ok yea I figured something was not right, I cant get the player to show anything now... frustrating ;)
Hello, if you are using Octane the current workflow is to export from LAMH (DAZ Studio) to .OBJ and later on import the .OBJ and .JPG into Octane and render.
This step is usually accomplished this way:
1) in LAMH, click FIBERHAIR and export to and export the hair. Mind that exporting a huge amount of hair will produce a very large and massive .OBJ, so here you'll need to do some experiments on your end, in order to find the right balance. For a Big Cat, I'd say to export at most 400-500K hair. One trick you might use is to eventually double the size of root/tip width, so that hair strands look larger and provide more cover
2) after some time, according to your system resources (i give granted you have a 64bit system with at least 8GB of RAM), you will see the geometry fur appear in the DAZ Studio viewport, laying over the model
3) now, in DAZ Studio, menu File->Export to OBJ; this will produce all the .OBJ files and textures you need, so that in Octane you will be able to load both the model and fur with textures, and finally render.
If you need support you can also contact me directly at 'info@alessandromastronardi.com'
PS: on a side note, LAMH hairs do not indeed show in the Octane render viewport, simply because there is no functionality that translates LAMH hair to Octane primitives yet. However, IIRC, in LAMH 1.5.15 tringgering the Octane window shouldn't cause crashes anymore.
Close studio, restart your computer and load a fresh scene
open the LAMH tab under edit windows tabs at top of DAZ
make sure octane window is closed though!!!
You will see an option to export as obj
ignore warning about overwriting existing hair as there is no obj yet, it gives that anyway!!
It will put an obj and map in your LAMH folder you can choose load in scene but that is very crashy is better to close after, reopen a fresh scene and import the hair obj and apply the texture map in surfaces as the existing scene is very likely to crash deleting the renderman curves and closing the player anyway for Octane.
thanks, for some reason when i use Create and LAMH UI loads i can not get any of the scene objs to load at all, it shows the Big cat, light and plane/floor, selectecing them and clicking import button nothing happens just default blue screen.
Any ideas whats going on?
DAZ 4.7 im using
Ah TY Allesssandro, I have ORDS 1.2 and it is very crashy with LAMH
but that does not deter me easily!!!
Ok, I think I get it, teh work flow anyway. System is i7, 32Gig RAM, Titan 6 Gig GPU, 2X RAID 0 Harddisk etc... its beefy.
I rebooted my system, Opened DAZ and loaded Big cat (not LAMH preset one) only in the scene.
Now I cant get past activation screen!!
I put in the SN it says restart - I do , and every time I go to Create New LAMH obj I am prompted to put inj SN.
Is there an activation code I should get also, I dont see it in e-mail or DAZ account.
Did you read the manual? When you load, for example, the Leopard from the Content Library, and click 'Show LAMH Editor' from the LAMH Pane, the LAMH ui shows up with the blue screen, as you say. At that point, select the DAZ Big Cat in the LAMH combo box, and click the button at its right side (see attached screenshot), to load it in the LAMH canvas. The model will appear with guide hair, and you can go on from there.
I just sent you an e-mail
Hi Wendy, does it crash also with latest LAMH 1.5.15? If that it's odd, I'd swear we had that fixed.
read teh manual, watched a couple YouTube videos, watched your videos on the blog too.
I click that button and nothing loads, same blue default UI screen no matter how hard i press the button ;)
im in an endless loop with activation screen now
my bad on the activation, did not catch the "follow the link to activate" on screen.
sorry
I have done several renders with a DAZ LAMH -> OcDS plug-in workflow. I simply applied the LAMH preset to the animal posed and then used the "Fiberhair" export in LAMH to generate real geometry. This can then be processed in Octane without issues as long as you have enough vram. Here is an example with the Racoon in one of Stonemason's nature environments. This was done with my GTX 780ti with 3Gb of vram.

id love to know how you pulled off the convert to obj re import, i did this and when i open the octane view port i get a view port that is stuck in waiting forever, I used the default settings for panther - converted to OBJ, cut the hair in half from original setting, and its seems stuck
I also then tried to export form DAZ the charterer base and converted obj and load into stand alone octane. It pretty much freezes my system into non useable
The system is pretty beefy, 2X Titan 6gig GPUs i7 proc and 32 gig of ram
Looks as though I should have read forums before buying this product as for me its not going to work if its taking hours to load into view port or not at all.
I would suggest the vendor take this Octane compatibility statement off the promo page or at least clarify taht its limited in use.
ok I got it to render after taking the hair count way way down, 100,000, from the default of 1,500,000, so it looks like it will work with octane plug in with obj export option, not surehow realistic the panther will be as one mentioned its a lot of fur.
Sorry for being such a b@#$#@ tch , the product looks fantastic and if it can work half as good as the DAZ render shows in octane id be happy
Thanks again for all the posts very helpful
Hi Wendy, does it crash also with latest LAMH 1.5.15? If that it's odd, I'd swear we had that fixed.
honestly not tried lately but may now thx
Hello, unfortunately the information has still to be vague. There have been contacts with the maker of the OctaneDS plugin and the common aim is to enable LAMH hair so that are read natively in Octane, thus sparing all this massive task of exporting/importing to/from .OBJ. However, the process has stalled for several reasons (I still have some life issues to sort out), and little time to dedicate to this matter that indeed is in our top priority list.
Also, another thing that constantly set us back in time is the almost complete lack of testers. This is not a critique of any kind, as I do understand that most users just want to have fun and spend the limited time they have enjoying making their creations and there is no spare time to devolve in testing and report. However, we lack proper and constant testing on new features or fixes that we believe to have addressed. That is to say, that as much effort we put in it, it's difficult to establish dates of any kind.
Ok, this morning I took some time to try the LAMH+DS->Octane workflow. I used my PC Win7 64bit, i7-3770 3.40Ghz, 32GB RAM, nVidia GeForce GTX 760 4GB. Software versions: DS4.7, LAMH 1.5.15, Octane 2.03 64bit.
Here is the process, step by step, with images.
1) Loaded the Leopard in DS directly from the Content Library
2) Started the LAMH ui, loaded the Leopard in, and used the FiberHair export, without changing any setting (thus 1.500.000 million hairs which is a huge amount). Export time 11'45".
3) At this point, the monster mesh is loaded in DS. My graphic card is able to decently have a responsive viewport, even with such amount of geometry. In any case, in order to speed up things, it's not a bad idea to switch the viewport draw mode to 'bounding boxes', in order to save GPU memory and calculations. Also, I suggest to set DS preferences as displayed in one of the images below, in order to increase performances and avoid crashes or bottlenecks caused by handling massive data. And of course, prior to next step, close also the LAMH ui for the same reason, i.e. save CPU and GPU resources.
4) Now, from DS, export to .OBJ. Please note my export options: I'm not sure (I didn't try) if Octane needs normals from the incoming mesh, or it recalculates those. If the latter, you could uncheck the "Write Normals" and save time. In this case, the export lasted 12' 22". You can see that the resulting .OBJ file was a little more than 2GB.
5) Closed DS, and started Octane 2.03. Loaded the mesh and waited for Octane to elaborate the mesh: time elapsed about 14'. After that, I added a few nodes for the environment, lighting kernel and let it go for 4-5 minutes. Render result attached.
So, for me it worked pretty well: I used some "precautions" which are needed when dealing with such large data sets, but had no issues of any kind. It goes without saying that a good 64bit system is needed. And patience.
The last set image (damned limit of 5 images per post)...
So, to paraphrase what you said "I would suggest the vendor take this Octane compatibility statement off the promo page or at least clarify taht its limited in use.", of course the use is 'limited' in a way that the user should experiment and find the right balance. Ain't LAMH or DS fault if a 2GB .OBJ file can't be loaded in Octane, or else application.
Having a fast PC with plenty of RAM allows for large data sets (in this case 1,5M hairs); with less powerful equipment, tuning down is required.
You seem to have a decent system, similar to mine, so I'd like if you could give it a go again.
