I’ve been doing some tests to see about using scattered proxies for my grass in archvis instead of displacement and or vrayfur. Sorry about the bland scene, but just would like to hear if it looks passable as grass?
All grass is using vrayscatter plugin with modeled blades turned to vrayproxy. At rendering time, scene has 183,950,520 polys. I used 5 scatter objects each generating between 1800 and 15,000 copies of a 36" square path of proxy blades…
well it looks much better then displaced grass imo. But why limit yourself with straight up pointing grass as if it was displaced? you can do all kinds of things with it now
Thanks Morbid, and you’re right, I could make the blades more curved for next time for long, wild fields. (This was originally going to be short, manicured grass; when the blades are only 2" max, there is little to no bending… )
Yes, its looking good. I’d like to know what each proxy looks like - are we talking 1 blade of grass in a proxy (doubt it!) ore 100 or 1000? How do they tile together? Are they square patches of grass?
@ skogsalle, @1200x675,
LC peaked at 1099.2M
BF peaked at under 1200M
@ raistlin, I scattered many blades over a 3 foot square area and collapsed it to poly and exported as vrayproxy. I’ll probably try some more irregular shapes in future attempts.
@ cubiclegangster, yes, maybe a bit much, I have reflection and environment overrides using the vraysky in the vray: environment rollout. In the 2sided mat, trace reflections is “off.”
@ tricky, I’ll make a wire of the proxy soon
Here is a feeble attempt with the sss2 material. BTW, I have no idea how to use that material!! Only the near short grass has the sss2 material applied to it.
some of the best grass I’ve seen - looks asesome, what I love is the idea that you can really go to town with different types / shades of grass, I’m getting inspired to do some of my own tests - nothing quite like uisng geom to represent geom, all the fussy with hair and fur / vray or not can break you’re heart.
1200 mb is nothing! well atleast not much more than what the old displacement would use… great!
how does vray scatter work? Is the grass scattered only at rendertime? Or do you constantly have a couple of thousand proxyobjects in your viewports?
Are there any limitations on how many scatter objects it can handle? sorry for the slightly offtopic…
I think it’s a great way to make grass. Couple of images below from a test I started. The job went away and I haven’t had time to go back and fine-tune, but these are vrayproxies scattered about. It’s about a 1meter square patch of various blades. The geometry was kindly given away by Herve on the Maxwell forum - credit for that goes to him.
One of these days I’ll get back to it and fine-tune the materials etc, but looks pretty good even like this IMO.
