Hello,
I am trying to explore vry fur and max's hair and fur for making realistic grass. I am using max 8 and vray renderer. iam having some problems with vray fur and max's hair & fur modifier. If I try to render it in a simple scene say just a plane for ground and few boxes as buildings, I can get a good result very quickly, where as if I try to render it in a complex scene with rpcs, max gets crashed. Guys please tell me if there any solution for it.

Also tell me is there any other plugin for realistic grass which supports vray renderer.

For exterior images in 99%, you DO NOT need ANY kind of sec rays, so:
1. Turn OFF sec rays
2. Also if your building is not too much detailed, go with IRRMap > Very Low/- 20/20
3. Make dynamic memory limit to 1-2GB and LEAVE static geometru as difolt.
4. Try with Vray displacement modifier for grass its better choice than VR Fur/Hair, lower the subs for modifier to 128-256 for 15-20m distance or leave at 1024 for 2-5m.
5. Try some of above

are you using rpcs with vray...they are not a good combo,,,whenever rpcs are rendered in vray max usually crashes,,,

hey! thanks for your suggestions guys...
i will go thorough these settings...
and also tell me one more thing... if rpc and v-ray is not a good combination..which renderer supports rpcs well. cause I heard that rpcs give problem with mentalray also..

dra3

the only thing that supports rpc that i know of is the default scanline of max...

I was not aware of that, it never happened to me. I have this one client that insists on RPCs when I do their exhibition booth designs, which I fully understand as it gives the client a sense of scale.

But I render them fine with vray, I mean theyre RPCs so they dont really look very good, but my Max doesnt crash at all.

@ okmijun
I tried the settings you suggested. But even vray displacement modifier crashes max when rpc's are there in the scene.
othewise vray displacement renders fine. STILL HAVE PROB> WITH VRAY FUR WITHOUT RPCS ALSO,same with HAIR AND FUR.

@ sterealkey
even I use rpcs with vray , it renders. BUT when I put rpc and apply vray fur or Hair and fur OR vray displacement modifier for grass my max gets crash. if I render it without RPC and the scene is heavy then only V-ray displacement modifier runs well and if the scene is simple; anything without rpc runs well.
I think Vray renders rpcs; but vray fur and rpc doesnt run well. If possible you also give it a try, may be you can find some solution to it. Mean while I will try the same things with Max 9.0 may be max 9.0 can support vray well.
