Bake Geometry Textures defaults to DirectX normals? 2026年3月24日13:04
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.
Bake Geometry Textures defaults to DirectX normals? 2026年3月22日8:00
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

I wound up changing to a local license for my situation.
I actually been using a local license server myself ever before. But a few weeks ago after an update this license server started acting weirdly, maybe caused by the same bug that also caused this thread here to start.
After a lot of trial and error and after having to fiddle with my local server every single time I started Houdini I finally switched to online licensing in the hope of remedy.
With online licensing I only had to log in once a day or so... but now it looks like everything is back to normal again.
