Simple material converter

[JuhaW]

Convert Blender render materials to Vray material nodes.

Supported with image textures: diffuse,specular, alpha, emit, bump, normal
Supported without image textures: diffuse, alpha, emit
Download script: https://github.com/JuhaW/VrayMaterialConvert


Example: Sketchup model imported to Blender, not my modeling.

Awesome! This looks to be very useful. Can you explain the usage? For some reason it's not showing up where I expect it to when I install it. Is it supposed to add an entry in the Render Layers panel under Node Tools? It's blank for me.

Its that __init__.py file, download it, load or copy/paste into Blender text editor and run it.

Ah, I thought it was like your other addons that made a button in the tools. I ran the script on a file that is a sketchup file, converted to obj, and imported into Blender. I got the following error. Is there a different import method you use for SU files? I use obj format so when I import I can use "Keep Vert Order" to make it all one mesh (instead of hundreds of component meshes)

I use Pcon Planner importing .skp files, then export .fbx or .obj and import Blender.
I have noticed problem with .fbx file, normal maps are gone when importing Blender and importing .obj file normal maps are there but they are handled as bump maps because Textures > Image sampling > Normal map is ticked off.

Seems that you are running the script vanilla Blender build ?

[andybot_cg]

How do you get anything more than diffuse maps from SU? Does the Pcon Planner software convert a specific renderer's material info?

Yes, just the straight V-Ray install.

Diffuse and reflection colors and transparency. Could you upload .blend with material where material convert gives error ?

The internal converter was working at one point, but not lately (like since version 2.77)

Diffuse and reflection colors and transparency

How would this get applied in Sketchup? Native SU only has diffuse.

It converts without errors.
I dont use SketchUp for modelling, I just download models from 3dWarehouse for testing.

JuhaW - Seems there was a problem with the .obj file I tested it with initially (unless the build I had installed was giving me trouble.) Either way, with a fresh build, I tried a few others and it works perfectly. THANK YOU!!

thank you, for time saving tool
