BRDFHair4.zip

Hi!

If someone needs here is updated version of V-Ray/blender python script that adds new BRDFHair4 material.

Unrar the file and place it into Vray-Blender/2.79./scripts/vb30/plugins_desc/BRDF

have fun!

Smth wrong with the attachment, may be .zip?

Yes there was something odd with rar, but looks like this zip file is working.

Looking nice. Remember that there is also Hair sampler that gives a lot of control for hair.

Haikalle, where did you get all those Hair4 material parameters and attributes and so on ?

[haikalle]

In windows press "Start Menu" and select "Chaosgroup -> V-ray Standalone for x64 command prompt". Then you can see all standalone nodes when you write: plgparams.exe -list
and then you can see specific params of node like this: plgparams.exe BRDFHair4

Chaosgroup has made it very easy to add those nodes into v-ray/blender. I have begun to write BRDFToonMtl but it takes a little bit time because there is a lot of params in that node.

Hi I am having problems rendering hair, it only renders black. I have the hair node conected to a single material node which is conected to the Material Output node. Using CPU and not GPU. Material is applied to a Blender Hair Particle system (maybe I need to bake it to geometry?). Need help please. Thank you!

P.S. I have converted the particle system to geometry and applied the shader to the new hair and no matter what I try it renders black.

Keep it Hair particles.
