24 Smart materials for substance painter with project.
Attention! Please make sure to use latest version of Substance painter, because I make free smart materials updates with newest versions.
PS. Use the project or click on the add "+" on texturing settings to create scattering/emissive channels and then turn on sss/emissive on shader settings. If you need to change scale details, play with the "curvature/thickness" settings . UV, scale and baking is important too. For more info go to: friedcanvas.com or hit me with a question! Thanks!
