We are gearing up for a new stable release soon and because the changes needed for this are quite involved, support for models which use an emissive texture instead of a diffuse one will go out when the next beta cycle starts.
Hi.
In this texture format, quite a lot can be included. It would be great if you could somewhere document—possibly in the release notes or in the documentation—which specific texture features it supports at the moment, along with an example of how to verify it.
