Vray Proxy Problem

Hello, I downloaded a plants package from food for rhino. It contained many meshes with each proxy besides it.
The package also contained jpgs.

Problem is that I cant render these into my model. No matter what I try they are not as they really are.
I tried importing the vrmesh into my model, but it chages color.
Then I tried creating the vrmesh again from the original mesh, but it also changes color when imported.
I then tried making a block from the original mesh and copy pasting into my model, but it loses the material and it turns to defuallt.

I came across this thread:

similar problem. It eventually got resolved by changing the settings of the materials it seems. But I have no idea how to do that.

After importing:

Edition window:

All those “materials” are simply different color combinations.
I cannot load the original “materials” of the tree because they are no materials… What should I do to relink the original texture of the trees?

I have same problem. Did you fix it?

I think I did by simply finding a way to relink the correct jpg and texture to the material in the material options, In the end I ended up using only two of the trees so it was not that hard.

Hope someone has a better way.

tell me if I understand correctly:

you have a 3dm file, this file contains several plants a mesh version with associated materials, and a proxy vray version without associated materials.


Are the mesh materials vray material or rhino materials?

I would do that, to simplify:

  1. delete all the proxies.

select all the meshes and type the command " visConvertRhinoMat "

Select the meshes one by one and recreate the proxies, you will see that every single proxy created will have associated a vray multimaterial with all the textures in place. :wink:


I’m not sure if this is a bug or something I’m doing wrong. I have an object composed of many meshes that I want to transform into a vray proxy to use in a scene. The meshes are not grouped or in a block. Each of the meshes has a material assigned with V-Ray Material Asset Editor. These materials have been converted from Rhino materials. The file was originally imported from a sketchup file. The file was in 2014 skp version and was saved to sketchup 8 version before importing to rhino. When I export the to a vray proxy (replacing the original objects) it works perfect. But if I then import the vrmesh file to the scene I doesn’t include any of the original materials.I have tried different ways to assign the materials to the objects but the results are the same.

Best regards,

Minimizing Faces in Preview when making a proxy from 10k to 5k did the trick for me, although I am having a problem bending the proxy and rendering it. It shows simply it not being curved. Any ideas why ?

what you’re bending is not an actual geometry, but a viewport representation - something to display in the viewport and give you a notion where the proxy will be rendered. Only basic transformations (translation, rotation and scale) are taken into account when rendered.
