Hello,
thanks a lot for this clever setup !
I have a quick question regarding the normal setup. The seeds (setupseed3 and setupseed4) used to randomize the red and green channels of the normal map are currently identical (seed = 11).

Was this intentional, or would it be better to assign a different seed for each channel?

Thanks !

Thanks Mark !

I'm also sharing the reply I've got from the support as it may help others finding this post.

Using recipe to add karma-specific controls to Mtlx Image nodes will add "Texture Width" parameter, which is the preferred way.
There's also "Mtlx Image Width" property (in material properties node under the Shading tab) to apply to the whole object instead of per-image.
Although render geometry settings LOP or karma render properties LOP don't expose it in their UI but it's also possible to apply to multiple objects or globally via edit properties LOP ("karma:object:mtlx_imagewidth")

Hello,

I'm bumping this post because i'm also interested about the workflow for ->

can i force the mipmap levels in solaris/karma? the texture node does not seem having a mip level attribute

There is a karma_width attribute on mtlx image node.
It's look like it decrease the quality of the texture.
When using a debug mip mapped exr, i can see the difference in the tiles loaded when increasing the karma_width.

I wanted to check if it was the correct workflow ?

Karma width attribute can be accessed with an editproperties node.

Cheers!
