Max + Corona v4 HF1
I stumbled across this recently (again) and saw that I've already reported this for Corona v3 HF1 and it's still present in v4... please resolve this, the problem seems to persist although I remember it being solved at some point in v2.
Repro steps:
Open the attached file, make sure both HDR files are linked correctly in Max.
- open the classic mat ed, you'll see the two environment maps in the top slots
- use either of the environment maps in the Environment override slot
- switch the used map to dome mode, render >>> block artifacts
- switch the used map to spherical map, render >>> all good
Make sure to use both maps to see how bad it can get :-/
Scene (Max 2018), textures and the resulting renders are attached.
