Arnold crashing many times

[pawel_karbarz]

I've got a simple scene, build from scratch (studio setting). I'm merge some 3d object from another scene (made in 3ds max) and textures (base color, orm, normal, sometimes opacity or emission) made in substance painter. I'm using default parameters in Arnold settings, just increase Camera AA to 5 and toggle on Global Light sampling. I'm using HDR map, 4 Arnold lights (point, 2x square, 1 disc) and Arnold camera. No other render pass or different features. How can I check what is the problem of the crashing (some logs, etc). I'm using newest version of 3ds max 2026.1 with updated yesterday MAXtoA 5.8.2.1

This is a minidump from last crash. I think the problem is denoiser in this case (I'm going to change from default to OptiX and check again).

[pawel_karbarz · Accepted solution]

I test this a little bit and Max stop crashing, it's probably problem with denoiser, OptiX crash just once for now in very long run. So, problem solved.
