Hey guys,

I'm using a flat grid as the soil for my environment. I texture bomb my texture and displacement a lot so we don't see any repetition.

I'm dicing it in the render and apply the displacement. The problem is that now, the points that I scatter on my flat grid aren't on the same position as my points with displacement.

Is there any way to easily get the diced & displaced mesh by Karma in SOP ?
Since I'm doing a lot of texture bombing, I can't just apply the one displacement in SOP and get the same result.

Thanks guys!

Hi, I’m running into repeated crashes with Karma in Houdini 20.5.332.
My scene is very simple: just a car simulated in RBD and a smoke sim behind it with a bit under 100M voxels.
I’m on an i9-13900K, RTX 4080 (16GB VRAM), 64GB RAM, Windows 11.
The issue is that after less than ten frames Karma consistently crashes with a segmentation fault. The crash logs don’t always point to the same place: sometimes it’s during volume evaluation (BRAY_VolumeSpan), sometimes in shader evaluation (MaterialX/VEX), and sometimes during EXR image output (IMG_FileEXR, OpenEXROutputFile).
It doesn’t seem tied to a single asset since the crash happens in different parts of the render pipeline depending on the run. I can provide the crash reports if needed.
Does this sound like something suspicious on my setup, or is it just bad luck hitting known Karma instabilities?

EDIT: I added a 4th crash dump that happened after my post. é

Thanks for all of your answer guys, I guess I've got what I need!
