Hello All,

Ive been searching the net and the forums lately on how to create tall meadow grass ive being doing i tby comping it in photoshop however i would like to attempt it in cg… howver i have just tried creating it with some othe methods ive read about mainly VRayFur. Im running vray 1.5 on viz 2008 using Dual Dual Core Xeon’s and 4 gigs of ram with the 3 gig switch.

Well ive followed settings such as the one found here:
http://www.vray-materials.de/forum/attachment.php?aid=77

however sicne its jsut a test im running teh test with very low preset in the GI and only at a resolution of 640x480

and well the render time keeps climbign its at 1 hour 40 mins and climbing on the estimate… what am i doing wrong?

anyones thoughts would be helpful

humbly yours

lost in a field of flat grass

Hi Ryan,

It could be your base geometry that’s the problem. I made some rugs for an interior using VRay fur that took about 30 mins to render. After adding a subdivide modifier the render times dropped to under 2 mins.

Might be the same problem…

thanks for the tip dan,

i tried it however the render times still went up to an hour + a 10m x 10m plane

im going to have to find a better way of makign the tall grass :frowning:

For a large scene, where rendertimes need to stay low, forgive me for saying this, but I’d just model a few pieces and starting instancing. You’ll get the best rendertime and best control that way.

Oh well, it was worth a try.

I think I used a size of about 50mm, even then the lightcache does initially think it’s going take a few hours but then suddenly the time drops to less than a minute.

thanks everyone for your suggestions im going to try a them and keep playing with it!

thanks!

When using a large amount of fur, displacement or vrmesh it will speed up your renders a lot if you increase the dynamic memory to around 2 GB.
