Karma XPU texture resolution limit?

Hey all,

Just testing out Karama XPU and I noticed the texture resolution of my renders seem much lower with XPU vs CPU render. I'm wondering if there is a texture resolution limit settings somewhere or if this is hard coded as part of the alpha?

See CPU and XPU render comparison attached.

Thanks,
John

There's a limit of 2K per default at the moment.

To go further, set the env variable KARMA_XPU_MAX_TEXTURE_RES, for example:

export KARMA_XPU_MAX_TEXTURE_RES="8192"

for 8K max.

Careful: The memory management right now is a bit experimental. Use very carefully.

Thank you! That did indeed work, I'll keep an eye on memory but I noticed it took a while to load with this env var set

I'm having the same issue. Only it doesn't seem like setting the env variable changes anything in karma. Am I typing this in correctly? or am I missing a step?

it should be for example KARMA_XPU_MAX_SHADER_TEXTURE_RES = "2048"
