converting to nodes error

[andybot_cg]

I am getting an error converting materials/ textures to nodes. I'll try to get a small sample file together. Here is the error text:

V-Ray For Blender Converting material SW_7004_Snowbound
Exception = 'KeyError' 'bpy_prop_collection[key] key Fog Color not found'

Thanks for the fix Andrey! Working great now

hi sir, where canwe find the convertor? thanks

[andybot_cg]

It's part of the program. Look in the scene tab for the tool to convert the materials.

thanks, andybot_cg

I find a bug with the convertor
1. import this obj file
2. run the material convertor
3. I get

The converter isn't working again! converting from internal blender materials gives an error and stops working when textures are present in the materials. This had been fixed back in March, but the builds for the past few months have been broken.

This error is still in all the current builds I have an old build installed on one of my machines just so I can use the converter. Otherwise, converter stops every time when encountering a linked texture.

[andybot_cg]

This is still an issue in the latest builds. It seems the converter stops and is not able to connect all the nodes. When it gets to the first linked texture it stops. Here's the error report, and here's what the incomplete node tree looks like when it stops (the nodes are initially all on top of one another, I moved them apart for clarity.) This same file converts fine in a 2.77 Blender build from March 2016 (vrayblender3-2.77-842478a-x86_64-windows.exe)

I would really like a working shader converter. I am still getting an error when I try to convert from internal Blender with linked textures. If the converter does get fixed, I would like it to convert to a standard material, with the image file node. Example below is the last build with a working converter, and next is the desired cleaned up import result. Error log as follows.
