I have just noted that all my models have problems with image base lighting and roughness.
My settings seem to have changed.
-For some models, the roughness map has no effect anymore. The roughness/glossiness switch seems to be inverted.
-The Image Base Lighting has no effect anymore too, no matter the environment option is enabled or not.
PBR option is checked, as I left it last time I uploaded my models.
I may have missed an update since I haven't checked my models for a while...
