[Bf-gamedev] PBR Workflow

[Juan Linietsky]

Mike, this is great news. We are going to add PBR in Godot soon too, so
having a proper workflow for exporting this (and not only to Unreal) would
be desired.
Regarding your points:

1) We have a node based and text based shader support, so something like
this would be pretty useful.
2) I think this is more tricky than that, because nowadays modern game
engines all render in linear colorspace and later do tonemapping and gama
correction. Textures would need to be converted to linear (if they aren't
already). Also, we should be able to set global viewport/camera reflection
probes?
3) This may be troublesome because neither Collada nor FBX support this as
far as I know. I can make my own exporter easily, but we have no standard.
Do you have anything in mind?

Cheers

Juan
