Thank you!
Sadly C2 effects will not work on the 3D output of Baby 3D.
There are some effects you may already use in form of the lens effects introduced back in 0.82 (edge blur, distortion and chromatic aberration).
Also do not neglect the glow layer.
In terms of formats for the B3D Model plugin: .gltf/glb files are recommended. .obj files are also confirmed working. Generally I would suggest sticking to those.
If everything goes according to plan support for normal maps should be part of the next update.
Most other more advanced stuff regarding materials is out of the scope of what this plugin is supposed to be and will most likely not be considering at all before reaching 1.0.
