Hey,
All is in the title, I can't find an AOV to get a tangent normal map in karma, I get only a World Space.
Any idea to get a tangent, by a shader trick or something?
Any help will be very appreciated i'm totally stuck on this !
Thanks and have a good day
(PS : I also posted in Technical Discussion, before realise there was a specific channel, if a modo can delete it, sorry!)

I'm not aware of a built in tangent normal output. If you have normal maps, you could add a karma aov node to export the texture value before it's passed to the tangent normal node.

Hey, thanks!
But if I only export the textures value, it's not the mesh normals + the textures I guess?
I had this results with a bake node :
Unfortunatly there are issues with the bake nodes (part of the mesh are missing, and it's not clean, and the alpha cause issues, etc) and I try to replicate exactly this normal in Karma.
Do you know a way?
EDIT
------------------
I tested to render a custom aov normal and it's flat :
Is there maybe a shader trick or something to get the same normal as the bake ?
