This tutorial shows how to import textures from Substance Painter and Substance Designer into V-Ray for Maya and then use them with VRayMtl. Overview In this tutorial, we will export textures from Substance Painter and Substance Designer and then import them in V-Ray for Maya to demonstrate how they can be used with VRayMtl. In Substance Painter, we can work with either the Metallic/Roughness or Specular/Glossiness workflows to create shaders. The shaders then can be exported for use with V-Ray by using the V-Ray export preset. You can find out more about exporting textures from Substance Painter here:  https://helpx.adobe.com/substance-3d-general/home.html Want to follow along but don’t have a license? Step 1: Export Textures from Substance In Maya, create your textures and then go to File / Export Textures… In the  Export Tab , select the Vray Configuration and click  Export . Substance Painter comes with a VRayMtl representation and VRayMtl templates for the specular/glossiness and metallic workflows. You can find more information here:  https://helpx.adobe.com/substance-3d-integrations/renderers/vray/vray-next-substance-painter.html Step 2: VRayMtl Setup Create a VRayMtl material in Maya. Import the textures exported from Substance Painter/Substance Designer into Maya from  File  >  Import... . Link the textures to the input channels as follows: Substance Painter Texture Colorspace V-Ray Material Channel Diffuse sRGB Diffuse Color Reflection sRGB Reflection Color Glossiness RAW Reflection Glossiness IOR RAW Fresnel IOR Normal RAW Bump and Normal Mapping In VRayMtl parameters > Reflection rollout, disable the  Lock Fresnel IOR to Refraction IOR  option. Alternatively, you can leave it locked, but connect the IOR texture to the refraction IOR of the VRayMtl. In VRayMtl parameters > Reflection rollout, set the  BRDF Type  to  GGX  . Step 3: Adjust Colorspace of Imported Textures Change the colorspace to RAW for the Glossiness, IOR and Normal maps from the  File Attributes  rollout >  Color Space  >  RAW . Make sure that the colorspace of the Diffuse and Reflection maps is set to sRGB. This ensures that the textures are interpreted properly for a linear workflow. From Render Settings > V-Ray > Color mapping: Leave the  Color mapping type  to default  Reinhard .
