New free script from us – V-ray maps baking script. v0.05

Features: Bakes texture maps:  Diffuse, Reflection, Refraction, Reflection Glossiness, Refraction Glossiness, Normal Bump, Fresnel IOR, Opacity, Illumination.

Creates  VRayMtl  with all textures correctly assigned.

Can convert  exr to jpg  using djv_converter.exe (part of the  http://djv.sourceforge.net/  )

Ability to load custom render settings preset for baking. It reverts back to old preset.

After Baking:

Why?

– Renders faster . When all this mess is baked into maps, you get simplified result that in general render faster.

– Easier to share.  This also opens up options to convert your shader to VRMat and use it in Maya / Modo etc.

– More flexibility.  Baked maps could be used for other things like exporting model to real time engine or other renderers.

Instructions:

Select model you want to bake textures from. Choose only maps that you need (right click to deselect all). Make sure you have correct mapping channel selected.

If you want to use different rendering settings for baking, create preset and assign it in the script. It will use it at render time and reload previous settings at the end.

djv_converter and Convert to JPG are there in case you have issues with JPG gamma after rendering.  It will convert default baking format (exr) to JPG after baking is finished and use them to create VRayMtl

General notes:

• Use the same BRDF model on all the shaders you’re working on. Recommended: WARD
• Camera based maps like falloff won’t work.
• This script will bake complex VRayBlend shaders down to Single VRayMtl, but reflections, glossiness etc will be averaged and result may be different than original.
• Proper UVW mapping is required. No overlapping, No inverted faces. By default it looks for mapping at channel 10 (as usually lower channels are used for shading, and it can get messy)
• Doesn’t work with SSS.
• You don’t need lights / shadows / GI in your scene.

This Script is free of charge. I just hope it will help your pipleline in the way it helps us. You can modify it, but please let me know and share your code. So we can improve it further. Just remember: this Script cannot be resold in anyway.
