Is it normal, that Blender crashes with Caustic Cache, when there aren't any specular material in the scene? For example, if I change the dice material in B.Y.O.B.'s scene to mirror, it works fine, but when I change it to glossy (with minimum roughness and high specularity too) it crashes on the sta...

Can you post a test scene causing the crash ?

Currently I'm AFK, maybe later.

I have instant crash when I try to render any scene... Does it happen with any scene ? For instance, including the one posted above by B.Y.O.B. ? It didn't crash with B.Y.O.B.'s scene! However it always crashed before, even with a default cube and sun. So, I assume, it's something with my settings.

I have instant crash when I try to render any scene with caustic cache (path CPU).
I have 8 GB RAM. Maybe it's low RAM related?

I personaly think adaptivity should be revisited in general.

First of all, great respect for everyone involved in this development! It was really inspiring to follow it in the forum. I wonder that now that LuxCore has these new albedo and normal passes, maybe BCD could use them too. I can imagine, that it would give better results in some cases than OIDN. (Pr...

Anyway, thanks for your answer.

I will try to ask differently.
Is there a procedural noise texture (like Perlin) in BlendLuxCore that can be used with UV Map?

How can I use a procedural texture in BlendLuxCore with 2D Mapping?
Currently I'd like to use something like a stretched Perlin Noise (for randomised stripes) and I'd like it to follow the edges of the object.
So it should use the UV map.

For example if you have an object which is hard to render, but doesn't cover much space in the image, surrounded by background (easy to render). In this case full image sampling would waste a lot of samples on the background, even with adaptive sampling, while tiled rendering would stop rendering t...
