Strange Volume Artifacts

Hello, I've got some strange artifacts showing up in my renders. The weird thing is, they aren't consistent each time I restart the render. You can see that the object is a sculpture and the artifacts are showing up in the mirror reflection of it. It has the simple white soap material from the LOL l...

Geometry nodes

Hello, I'm not quite sure I even have the vocabulary to ask this question, but I'll try. Is there are way to separate out normals based on geometry? This would allow applying a material based on the z slope of the normals, for example. Attached is a screenshot of what it looks like in Cycles. Pluggi...

Re: Dispersion, reflections and this kind of staff

Can you tell us what you did? For future reference if anyone stumbles across this.

Procedural Brick or Stone

I'm trying to model the inside of a cathedral. I wonder if anybody has any ideas or tips to make large, seamless brick/stone wall type materials in Luxcore? Image textures are just too small for the task and I get major tiling issues. There aren't many tutorials online for procedural materials in Lu...

Re: Z-pass depth map

Where can I change those settings? I don't see anything about it in the documentation.

Re: Z-pass depth map

I think so too, but when I try to do that, I get a very flat result (see attached).

Z-pass depth map

Hi all,

I have a fairly simple question. How can I render a z-pass depth map in Luxcorerender? I want to use it to apply mist in Photoshop instead of the compositing tab. I'm not getting great results with the mist feature under the camera settings, so I don't want to do that.

Many many thanks
J

Re: Sharp lines in volumetrics ("godrays")

Thank you. Obviously a stupid oversight on my part! I see now that the angle was an issue too and washing the godrays out. You can see them much better when I moved the camera. But I also figured out what was causing the most problems: I didn't have a fully enclosed scene around my camera. So whenev...

Re: Sharp lines in volumetrics ("godrays")

I've tried that with no luck, unfortunately. Attached is a screenshot of the project's current state. Not ideal as you can see. It's really strange -- I've successfully added a good volume with godrays to the "HallBench" example scene using the same settings but I cannot reproduce it. Some relevant ...
