Hm. not really. So whats the magic behind?
Rendersettings please
More intelligent sampling strategy ?
VRayHairMtl4 ?
Vlado has a new year surprise for every one 
Now share it!
hehe this is amazing woow
render time when from 26 min to 5 min! please share the details.

i know, u have a new cpu
Hm. not really.Perfect
RendersettingsRender settings are as simple as you can get: dmc image sampler 1/4; brute force GI with 4 subdivs and 3 bounces.
More intelligent sampling strategyYes… a bit cleverer sampling of transparent hairs.
VRayHairMtl4Nope; it’s still hairmtl3
i know, u have a new cpuNope, both are rendered on my laptop
Anyways, it should be in the nightly builds already, you can play with that…

Embree, maybe?
No, Embree does not support hair.

Vlado,
I’m getting jealous looking over my neighbour’s fence at some of the vray for maya features - I’d imagine the first thing you need to do is get the translation between each program and vray itself, and then gradually start supporting the features. Is the plan to eventually have one vray core and then start linking each ui to it so that there’ll only be one vray as such with the same features rolling out to every program at the same time?
Cheers!
John (for 3dsmax)
The V-Ray core *is* the same; both implementations share a lot of code. For example, the changes that I made for the Maya hair shader are automatically included in the 3ds Max one.
and then start linking each ui to it so that there’ll only be one vray as such with the same features rolling out to every program at the same time?This depends; changes to the V-Ray core itself go into all products at the same time (f.e. optimizations). However, sometimes implementing a new feature requires a lot of experimentation; it makes more sense to focus on one platform while developing the feature as the code and the UI are constantly changed. Once the code is more or less complete, we start looking into porting it for other applications.

Ah, I understand. There’s a few very useful bits on the maya side which makes sense since it’s got such a heavy VFX user base. Must switch over at some point!
Does this improvement go into 2.40 (maya&3dsMax)? or 3.0?
Thanx
There’s not much time to test it properly for the 2.4 version… but we’ll see.
Best regards,
Vlado
Phew and I thought that it was just a simple trick with some special settings in the DMC/BSP of VRay.
I will check out the new nightly builds soon.

Vlado does this improvement affect shave and haircut hair rendering?
No, but I sent the shader changes to Joe; it is up to him to integrate them.
Best regards,
Vlado
K I’m in the dark. So what is it that the render drop by 80%?
Its pretty great result!
