Thanks for reporting, the bug is already fixed and will be deployed to production soon. Meanwhile you can disable temporal antialiasing in the postprocessing filter tab in edition mode. It should do the trick.
Thanks for your quick feedback.
I disabled all postprocessing filters from the global switch, even the lights and the background shadows. The issue is still present.
I only have the following maps on the materials of the model: diffuse, specular, normal, ambient occlusion, emission and transparency. I'm using PBR maps, specular workflow.
Maybe I was not clear enough. Disable Antialiasing in postprocessing tab:
This should be good.
Thank you! Was my misunderstanding.
