Hi
I am testing vray rt for production rendering and I get some small differences between the vray production render and vray RT.
some of the grass leaves looks more grey in vray RT than in the production renderer.
Any idea why.?
It is off course both rendered in VFB with same coloradjustements.
-
seems like a bug in the new beta version. works fine with 2.40.04
-
Chaosgroup have told me that this is a bug that Itoo haft to solve in the new Vray RT 3.0
-
We have not been notified about this problem. Anyway, the support for Forest in VRay RT was implemented directly by ChaosGroup, and includes only basic scattering, not Forest Color or other functions that would modify the rendering result.
Do you use Forest Color in your scene ?
-
I use your presets for grass... (I guess there is forest color in this or?? )
The grass looks wrong in VRay RT 3.0 and fine in Vray RT 2.40.04
Some of the leaves appears grey instead of green.

I just wrote to our contact in ChaosGroup about this issue. I will post here as soon i have some news.
-
Thanks..:-)
-
I just received their reply (it was fast). This problem is fixed for the next VRay 3.0 beta.
-
Fantastic... I have addressed this issue for them a couple of weeks ago, so maybe that helped... :-)
But they said to me that Itoo was responsible for this correction, so therefor I wrote here.
But thanks again.
-
the problem was not solved with the latest version of Vray RT (3.05.04)
There is still different colors when rendering in production and Vray RT.
Do you know when these issues will be adressed. ??
-
No idea, sorry. I will ask to ChaosGroup again.
-
Ok, i got their reply. It seems VRay 2.4 just produced some random result, which in some cases looked more correct, although really it was not.
Instead VRay 3.05.04 now should render the same result in RT... except if Forest Color tint or random texture options are used, because this plugin is not fully supported in RT: it just renders the default texture.
Our grass presets use Forest Color, so always will be some difference between VRay standard and RT. As reference, i've attached render samples of the "Common grass" preset.
I hope all is clear now... there was a bit of mess with issue. :)
