Is it reflecting the ground?
 
Old 09 September 2011   #47
The concrete driveway you mean? Because there is no grey groundplane in the scene, it's fully modelled and with an HDR domelight providing reflections.

will check tracedepth though...

Nope, setting vray material (reflection & refraction) trace depth and vray's render globals trace depth to something twice as high has no effect. Also, RT only has it set to 4 maximum, which seems to work fine.



Any other ideas anyone?

The only thing i can think of is that you might have reflection interpolation on which wont show in RT but will in the regular render.

I've also tried playing with the Transluscency slot in the vray2sided material, which affects it, but not in the way I wanted. And the 'reflection interpolation' is off in all the leaf materials.

could u share me the scene on PM?

so i could take a look?

cheers

Maybe itīs the fact that the trace-settings are so low in RT that you donīt get the grey reflections/refractions? So that when you render with the normal render it traces more leaves? or maybe the cut-off threshold is lower in the normal engine?

btw, I really like the darkness you get in your leaves. If you donīt mind, maybe you could share some of your settings?

^could be, but upping the trace depth in RT's settings doesn't result in the silvery leaves so doubt it. I'll write how I did everything once I get this problem sorted, it's basically Peter Guthrie's method adapted to Maya (http://vray.info/tutorials/leafmaterial/)

Does anyone knows if Vray Proxies works on a renderfarm? do you have to put the .vrmesh in a certain folder?

just make sure its in ur project folder, like data or something...
 
Old 10 October 2011   #57
You can have them on a server asvwell or from a shared library. just make sure to use unc path names
 
Old 10 October 2011   #58
unc = unique? sorry not sure...

Thought it would be interesting for you guys. I have been working on it a while ago. Used lot of proxies with spPaint3d (and looot of color-correction in nuke)

Don't know what it stands for but if you have the vrmesh files on a server or folder share, you can do it like this:

\\Servername\maya\library\trees\tree01\tree01.vrme sh

etc..

That way all render nodes will pick it up, if you use mapped drives:

L:\Library\trees\tree01\tree01.vrmesh

the nodes will fail cause they or vray standalone doesn't understand mapped drives.

I think the same applies for texture paths as well but I could be wrong.

Either way its probably a better idea to put vrmesh in a library system to make it easier to use in different projects like assets and saves disk space.
