Seems like a missed update for the image engine. @Jeroen-Bakker

@ericsego So there are two issues, the missed update and the unexpected baking result?

This is more than the missing update of the Image Editor, the bake is wrong.

There was similar #95471 (Baking normals gives wrong results (caused by normals MVert refactor)), but apparently the fix was not enough...
Will check.

Thanks for the investigation.

Hope you ll find a fix. The only workaround I'll find is baking the HD to LD object (which require 2 objects) but but it is less practical than multires.

Thanks for your help.

Best regards

PS: could you tell me when you ll find a fix. Thanks by advance.

#96401 (Bake normals for multi-resolution object is broken)

Philipp Oeser commented

Ah, the wrong bake is actually the same as #96401 (Bake normals for multi-resolution object is broken)

Philipp Oeser commented

2022-03-21 16:44:08 +01:00

OK, so since the wrong bake is already covered by #96401, lets concentrate on the missing update in the Image Editor after baking here.

Caused by 507a4deef1
But probably just needs a fix like the one for #96030
