I don’t know how to express it in another words, but it is simply broken.
Create a new illum material apply it to anything in the scene.
add white diffuse and change specular color … then nothing specular doesn’t change.
saving makes the change appear then nothing again.
the same with emissive intensity…nothing if you don’t save the material. no realtime feedback.
Add to this a huge freeze on saving a material this is making the engine completely useless for me.
