Hi there,

I just noticed (in a painful way) that the Bake Geometry Textures COP defaults to DirectX normals instead of OpenGL.
Or in other terms: The green channel is set to "Green down", which is another way of saying "DirectX normals".

I wonder why this is the case as just about any offline renderer (Arnold, Cycles, V-Ray and especially Karma) uses OpenGL / green up normal maps.



Is that an oversight or is there a deeper reason for this?

EDIT: And I just noticed that the Preview Material COP expects DirectX normals. :P

Hi!

It is indeed very painful that Karma expects the opposite.

It was a hard decision, but ultimately it just didn't make sense for a COP to output Normals that are alien to the rest of what Copernicus expects.
Since this Baker was intended to also cater towards Games, we considered that Unreal Engine also expects 'Green Down' DirectX Normals.

OK, thanks for your reply. It's not the end of the world, just a bit "painful" indeed as you put it. But it's good to know it's not my fault but just the way it is.

Of course! If you have any thoughts to make it easier for you, we would love to hear about it in an RFE.
