Title: portal material affect backplate projection
Post by: Christa Noel on 2015-07-08, 04:29:20
I used a plane with portal material on the windows hole. nothing happened when i used usual scene environment without override but portal changes the backplate projection when i use direct visibility overrides. check the attachments.

edit:
i think it is corona bitmap related. i just changed the environment to vrayhdri and the result is ok, nothing happened like what i mentioned before.
and it happen too on thin glass refraction material with reflection set other than 0.

Sorry but I do not fully understand what is going on here. Is it only a portal that for some reason becomes textured, or is this some kind of backplate geometry + portal? Could you describe step by step how to recreate this?
Got it, looks like a bug.

Ok, diagnosed: use standard max bitmap with screen mode if it's possible. Corona Bitmap cannot be mapped onto geometry in environment mode. I knew something like this will happen sooner or later. :P

Perhaps camera map per pixel map could help here.

sorry, my explanation is pretty bad..
yes camera map per pixel maybe could help for a while, never thought about that. but I think it's better to choose to use vrayhdri or maxbitmap instead of coronabitmap until it fixed.
cheers! :)
