Max to Guerilla workflow for Hair/Fur ??

Hi there, I'd like to know....
What is the workflow to import hairs (I mean curves/splines/guides) into Guerilla ? Other than Blender->export curves to Maya->Guerilla. Is there a way using 3DS Max or other softwares ?
It seems that Alembic doesn't support curves or splines, it's automatically converted into geometry hmm

Help ! Merci

Hi Tetsuoo,

Guerilla is usable with other packages as long as they support Alembic (although hair support in the default Maya Alembic is quite rough for the moment.)
You can check Exocortex Crate for a wider support of Alembic on Maya and 3ds Max (XSI is also supported, but XSI is to be discontinued soon anyway...)

Cheers,
Ben

Ah, thanks for the quick reply ! I just installed the Crate package, well... After exporting Curves/Splines from Max, I can use them only with Replicate Guides, it's still can't be used as guide curves for interpolated hairs like it would with Maya curves.
So for now it looks like making hairs is for Maya users only... I'm still investigating.

Also I wasn't expecting for the imported splines to be renderable, I just hide it if they are in the way ^^;

J'y retourne...

Hi Testuoo,

That's odd, curves can be used for both Interpolate Guides and Replicate Guides modes.
Do you have a sample to send me (the Alembic file with both scalp and guides), I'll have a look at it.

Cheers,
Ben

Hi !
Here : http://www.mediafire.com/download/svxfx … Export.ABC

Very simple scene, a deformed plane, and 3 type of splines : arc, nurbs curve, alembic spline (this one really do nothing). Made in 3DSmax.
When exporting with Alembic there is no specific options about curves/splines, but they are present. I think with Maya curves it would not show on the render (make sense for a curve), so I'm sure there is definitely something fishy here big_smile

Hey you know what... La révélation ! I found the problem -_- I had to expand the selection radius !! -_-

(Juste comme ça, d'un claquement de doigts. Parfois faut lâcher l'affaire, y revenir le lendemain et bam ça vient tout seul)

For now it's interpolating around each curve not inbetween, I'm searching. Something new to play with !

Hi Tetsuoo,

Yes, the procedural interpolates around using the selection radius, not strictly in between. Use Density maps to properly refine the edge of the grooming/brushing.

Cheers,
Ben

To render hair and fur coming from max you can use Ephere Ornatrix, it has his own alembic export for curves and work pretty well here.
Even animated hair seems to render quite well in guerilla
