Vray support for HAIRFARM, a must!!

[G0M0]

Does the new VrayHairMtl works with Hairfarm or only with Ornatrix?
After few tests I've got no positive results.

Well, if someone was interested with my previous question:
- it doesn't work with HairFarm.
Are there any plans to support it?

For the moment it only with with VRayFur, the 3ds Max Hair&Fur modifier, and Ornatrix. I do not know what will happen with HairFarm.

Hi Vlado,

For the moment it only with with VRayFur, the 3ds Max Hair&Fur modifier, and Ornatrix. I do not know what will happen with HairFarm.

I´ve written the HairFarm developer and asked him to get in touch with Chaos for his SDK. While HairFarm supports mr prims and VRay kind of supports mr prims (or vray primitives) as well,
I hope it will not be such a difficult task to get a connection between both to use HairFarm prims with VRay. If this could be solved, it would be the perfect solution for hair we believe.

We would very much appreciate if you could look into this.

Thanks,
Martin

...and VRay kind of supports mr prims

We don't support any mental ray stuff; we just use that particular option to check if the hair&fur should be rendered natively by V-Ray, purely as a user-interface widget. The fact that HairFarm supports mental ray means nothing to V-Ray.

Hi Vlado, thanks for your clarification. Would it be possible then to connect this HairFarm option to support VRay primitives ?

[vlado]

Of course; this can be done either by us (in which case we would need an SDK for HairFarm and some developer licenses), or by the HairFarm developers. I myself prefer the first option, because we have greater freedom to optimize the rendering (and there are a few optimizations planned for future builds).

Any news about this implementation Vlado?

By the way, I found a bug. When I place a blend Vray Mtl in the slot of the mr,shader of hair and fur, and rendering with mr prime, it crashhh. But if I put a vray hair shader it's ok.. can ou have a look at it? my blend mtl is composed of a vray sss2 blended with 2 vray Mtl for the reflection.

Thank's

Hi Vlado,

did you get in touch with Cem from Hairfarm ? Did you get the SDK from him so you can make hairfarm compatible with vr primitives ?
It would be really important and very helpful for our production.

Best,
Martin

Hi Vlado,

I'm new in this forum and really interested in this topic. Our company produced our last feature film with Vray and Hairfarm which was great regarding to speed, but our production quality suffered a bit due to Hairfarms missing Vray light + Environment effects support. I am currently working with style and pipeline for our upcomming feature film production, where good looking fur is vital. I'm sure getting the two pieces of software to support each other better would really simplify the production and enhance the visual quality.

We are likely to change from Fume to Phoenix FD if depthblend will work properly.

Do you have any idea about what to expect regarding speed comparing Vray Prims and Hairfarm prims? Hairfarm is extremely fast due to flat camera facing hairstrands. How does Vray hairprimitives work?

[vlado]

We got an SDK for HairFarm, so we are looking into what are the options there. It will be a while before anything usable comes out of it though.

It will certainly not be as fast and will be comparable to the speed with which we trace other hair stuff (Hair&Fur and Ornatrix). Even though V-Ray also uses strands rather than actual geometry, the raytracing is generally a slow operation. So if speed is your primary reason to use HairFarm, it will go away when raytraced by V-Ray. (We do plan some general optimizations of hair tracing for future builds, but they will not be specific to a particular styling plugin).

Vlado

I see, thanks for the fast answer.

I guess we have around 6 months before full production starts, so there is some time for the final decisions. I cross my fingers!
