Compatibility with 0.9.7 is now breaking, so it's time to choose.
You can change to the new 0.9.8 branch to remain on the previous beta build.
Or you can stay on the beta branch with me and something about a rabbit hole...
0.9.8b
Tessellation is back and improved in the new rendering backend.
Subdivision/curvature can be used with or without displacement maps.
Displacement maps can be used with or without subdivision/curvature.
Per-mesh texture mapping scale can be calculated in the model editor. This is best for organic shapes.
Terrain tessellation is not yet supported.
Tessellation and displacement is complicated, but you can do some amazing things with them, and I think we have a system that will work with all models.
Also:
Lots of video quality settings added in the editor options.
Refraction in transparency works in the editor now.
Material properties are divided into more categories now.
If metalness = 0 and roughness = 1, no specular reflection or Fresnel effect will be shown in PBR shader.
