Vray Proxy

[Winniman]

I am not sure if this has been mentioned previous already.
Can Vray for Revit uses the Vray Mesh Models like 3Ds Max does?
(Aka, adding Vray Proxy support in Vray for Revit version.)
Thanks,

This now works in v3.60.02, it's glorious! I've used it for trees in some renders. Also very useful is the ply2vrmesh tool (command line only, is found here on my install: C:\Program Files\Chaos Group\V-Ray\V-Ray for Revit\tools), so you can convert .obj files to .vrmesh. VERY useful.

Maybe this functionality could be extended a little bit, so for example Furniture or Plumbing Fixture objects (which are not so detailed in the Revit model) could also be overridden for a VRayProxy just for the time of the rendering, so the Revit model does not get loaded full of high-poly objects.

You can place RPC furniture and replace it with proxies (the same way like with trees).

Hi! and how can we use them? I´ve tried with the ply2vrmesh but it´s really hard to asign a real material to the leaves

Thanks.

Itziar, the .vrmesh format holds info only about the geometry + its material IDs. You need to create the V-Ray materials separately and assign them to the material ID's.
More info can be found on our docs page: https://docs.chaosgroup.com/display/...IT/V-Ray+Proxy

Thanks Ana. I´ve already read the document and tried. The problem is with the leaves, it´s very difficult to recreate a real leaf.

I think you can use the following webinar as a reference. Jump to 20:00 min.
The two-sided material is not supported in the current version of V-Ray for Revit, however, the approach of using a Generic material preset is valid.

Thanks Ana, I´ll see it.

Hi all,

Following up on this topic, in V-Ray Next for Revit we've extended the proxies functionality as follows:
1. Families of various categories can now be replaced with either a V-Ray proxy or a V-Ray Scene file (.vrscenes are render ready files, meaning you don't need to recreate their materials)
2. We have added a randomization functionality that allows assigning random scale and rotation to a proxy/vrscene overriding an instanced Revit family. As an example, if a tree in Revit is instanced multiple times, and then overridden with a V-Ray proxy, the proxy instances can be assigned random scale and rotation.

Also, the two-sided material, which I mentioned in my comments above, along with various other materials are now supported in V-Ray Next. Here is a quick link to the trial.

Cheers,
Ana
