Hey folks ! Problem here driving me a bit crazy, I am trying to get a proper leaves material for differents kinds of trees, and as soon as I get a "thin" opacity map for pines needles for examples, I got a very annoying issue...
Not only the opacity does not react exactly the same, my leaves vanished when zooming out. Only rendering in xpu, no problem in cpu.
Cpu renders :

My Nvidia studio drivers are up to date, Houdini 20.0.653
I would think about some kind of mipmapping issue, but not sure.
Thanks for your repply, I just tried and indeed I have a better result. Is there any way to handle the mipmapping for a specific map ? Disabling mipmapping for an entire environment scene might be a bit problematic.
Could you decrease the mipmap levels just for that texture, but you would need to preconvert with imaketx instead of letting karma xpu auto generate .rat.
Hey ! Just found out that changing the Map filtering to closest helps a little bit. Otherwise my leaves are disappearing in the distance. Is There a way to totaly disable the filtering of a specific Map or to get a better optimization of a clipping / cutout Map ?
