I’m taking quick job where another artist packed in due to complications.
It’s a VRay scene that would render as well (and much faster in C4D)
The scene however has 200-300 materials that need converting from VRay mats to C4D, though they contain no special information other than diffuse texture channels.
Is there anybody out there who could write a script to bring those materials back into Cinema materials?
Thanks.
Just wanted to point out that my observation about speed differences is due to ‘not’ needing a GI solution for the particular shot. Where AR would be faster with a simple sun/sky setup.
no prob, as i said Lennart might be your guy then… he made great scripts also for me

You iterate the VrayMats , making new C4d mats
then transfer the shader settings.
Iterate the Object manager tags replacing
the tag material from VrayMat to the new corresponding C4D mat.

Stuart, did you get anywhere?
See the framework how it could be done.
Note, only checked with R11/Vray1.1 as
I don’t have Vray1.2 installed in R12.

Copy -all- into script manager and keep your fingers crossed 
// VrayMat_To_C4DMat tcastudios.com©2011
//
// In Material Manager, select all VrayMaterial to be replaced.
// Creates new C4D materials based on:
// Vray Materials DiffuseLayer 1 Diffuse Color -> C4D Color Channel
// Vray DiffuseLayer 1 Diffuse Transparency -> C4D Transparency Channel
// Vray Material Weight -> C4D Alpha Channel
// Vray Specular1 -> C4D Specular and Specular Color Channel
//
// Then replaces found VrayMat Tags in Object Manager
//
// NOTE! Only tested in R11 and VrayForC4d v1.1.
// Check UNDO and Vray enumerates for R12+/VrayForC4D 1.2, see comments in code

I wasn’t sure what you meant by iterating the mats, sorry.
I really appreciate the effort, the file is R11 file and if I can install an earlier copy of VRay, this will work.
In R12 it gives me all the relevant C4D materials, though texture channel doesn’t convert.
I see, something might have changed regarding containers in R12 then
(that’s how the textures/shaders are read and set in the script).
Just saw that the Vray Refraction channel is a better choice to set
the C4D Transparency channel.
Just re route the corresponding ID’s (From Diffuse Color Transparency
to Refraction ID’s)
Cheers

i will try this out 2morrow …i could have used this in two projects already and safe some time
thx
