Everlasting question: Cycles mats converter

[adam_radziszewski]

The updated material converter is now available for download! It converts Cycles nodes to various render engines, including V-Ray.

It also allows you to add textures to the node tree and create a basic material based on those textures.

Furthermore:


Node conversion:

• ColorRamp
• ImageTexture
• InvertNode
• ColorCorrection
• NormalMap
• Hue/Saturation/Value
• MixColorNode
• MappingNode
• Mix shader (Creates a Vray layered material if the algorithm detects a MixShaderNode, but only if Translucent or Glass is not used in the Cycles material).
• Mix
• Reads data from Principled/Glass/Translucent nodes.

I've released an update that improves V-Ray shader recreation, but I'm still seeing some differences compared to other render engines (see images below). This update includes:

• Support for Poliigon materials and models.
• Replacing Fast SSS2 with V-Ray Standard Material when subsurface scattering is used.
• Correct bump settings for normal maps in V-Ray Material node

Very nice work so far. I played around with v1.0.4 and most conversions from Cycles-->VRay seem ok. A couple of observations:

1. In VRay for Blender, the Displacement node is attached to the Object, not the shader, as in Blender native. Is there a way to throw the displacement map into a new Object node tree (connected to VRay object output). If so, you can also connect up a subdivision node to the Object Output, to support the VRay Displacement node.

2. Some of the linear, or B&W, textures are connecting color out to intensity in on the BRDF, when they should be using Out Intensity I believe.

As stated, nice job so far. Let me know if you have any questions.

[adam_radziszewski]

I wasn't sure if I should use "color" or "Intensity", I'll try to improve the output for the latter.

Regarding Displacement, you're right, I now remember that in the version for 279 displacement was in the object. I don't know yet how a model with several materials will behave, it may be necessary to add a popup that says that this object has more than one material. I'll do some tests.

Many thanks for your feedback.

I have started implementing Displacement for V-ray. Currently, it will only be available when creating new materials using the addon tools. Later, I will implement it for the converter. Can anyone tell me if this is a good Displacement setup?

Also, my addon allows you to save predefined material settings, such as for Luxcore/Octane. Which of the similar options would be good to implement in the V-ray tab?

[adam_radziszewski]

Can anyone provide me with a correct Vray scene setup using an interior HDR map? It can be the c00 map from Polyhaven, or what would such a setup look like? Do I need to use Environment nodes, Domelight, or something else? It's not intuitive to me. In Octane/Cycles/Luxcore, it's enough to connect the map to the environment.
