Material Converter from Cycles

[adam_radziszewski]

For some time now, I've been working on a converter from Cycles to other render engines. After the recent release of V-ray, I decided to add an implementation for this engine as well.

Today I released the 7th update, which includes, among other things, the transfer of Displacement. I wouldn't want this to be just a converter, but a tool that makes it easy to create materials as well, so the module for V-ray couldn't miss the ability to import textures.

I also recorded a video where I go through the conversion process for different engines, including V-ray, because each of these engines has its own quirks. This is probably the second video I've ever made, and English is not my native language, so I apologize in advance for any mistakes.

Below is the Video:

And here is the Changelog which mostly affected V-ray:

General:

• Improved all scripts.
• Detecting Bump Node from Cycles Nodes
• Added two new premium modules for other render engines:
• Convert all materials in the scene to Octane or V-ray: (Importantly, if it detects that a material already has the appropriate nodes for that engine, it will skip to the next one.)
• Convert material in selected object for Octane and V-ray: (Importantly, if it detects that a material already has the appropriate nodes for that engine, it will skip to the next one.)

V-ray:

• Added Displacement option.
• Added Color to Float node, if after conversion we get a connection from Color Socket to Float socket.
• Transferred Displacement value from Cycles node to V-ray node.
• Resolution setting: either by reading the resolution of the used texture or setting from preferences.
• If the imported texture is Roughness, it is automatically inverted, so there is no need for an invert node.
• If we have a Glossiness texture in Cycles, the invert node is skipped during conversion.
• If the texture is of non-color type in Cycles, then during conversion the V-ray texture gets Gamma corrected value to 1.0, Auto at least in my case did not work.
• During conversion, it reads what space the Normal node has and transfers it to the V-ray material.

I was unable to find funding for this project, so I decided to use Patreon, to which I refer anyone who would be willing to provide financial support: Adam Zorian Blender | Patreon
