This is a list of the currently supported shader models and texture inputs. We plan to add support for more items on this list in the future.

Name Support Notes
Subdivision
  • Flat
 No
  • PN Triangles
 No
Displacement
  • Height
 No
  • Vector
 No
Surface
  • Normals
 Yes Object space maps are not fully supported.
  • Detail Normals
 Partial Detail normal maps are baked down to the primary normal map which may result in significantly reduced resolution. Only UV Set 0 is supported, Detail maps which use UV Set 1 will appear incorrect.
  • Parallax
 No
Microsurface
  • Gloss
 Yes Roughness maps (invert checked) will be converted to gloss maps.
Albedo
  • Albedo
 Yes Albedo maps authored for the metalness workflow will be converted to standard albedo maps (specular workflow).
  • Vertex Color
 Yes
  • Dota Color
 Yes
Diffusion
  • Unlit
 Yes
  • Lambertian
 Yes
  • Microfiber
 Yes
  • Skin
 Yes
  • Dota Diffuse
 Partial Dota content is converted to our standard shading model. Not all effects are supported at this time.
Reflectivity
  • Specular
 Yes
  • Metalness
 Yes Metalness maps will be converted to standard reflectivity maps (specular workflow).
  • Advanced Metalness
 Yes Metalness maps will be converted to standard reflectivity maps (specular workflow).
  • Refractive Index
 Yes
  • Dota Specular
 Partial Dota content is converted to our standard shading model. Not all effects are supported at this time.
Reflection
  • Mirror
 Yes
  • Blinn-Phong
 Yes
  • GGX
 Yes GGX support uses an approximated method (for performance reasons) which does not match as accurately as Blinn-Phong. This is especially noticeable with rougher surfaces.
  • Anisotropic
 Yes
Secondary Reflection
  • Mirror
 No
  • Blinn-Phong
 No
  • GGX
 No
  • Anisotropic
 No
  • Newton’s Rings
 No
Occlusion
  • Occlusion
 Yes
  • Cavity
 Yes
Emissive
  • Emissive
 Yes
  • Heat
 Yes
  • Fluorescent
 No
Transparency
  • Cutout
 Yes
  • Dither
 Yes Dithered transparency uses an alternate technique, which is a mix of alpha blend and alpha test.
  • Add
 Yes
Extra
  • Custom
 No
  • Substance
 Yes Substance inputs can not be changed dynamically because they are optimized and compressed on export.
