Re: Realistic simulation of camera and laser

Hi CodeHD Opacity is not the same as transparancy in LuxCoreRender. Opacity makes objects vanish to set amount. This is the reason I did not have the idea to use opacity. I guess you mean "varnished", i.e. painted, not "vanished"? From what I saw in your example file, the behaviour of luxcore was n...

Re: Realistic simulation of camera and laser

This is an interesting topic for me as well. I tried this a while back with v1.6 with a 5-element lens system. I sent some lasers through it to check the focus and everything worked as intended. See the image attached. Even got nice ghosts and shadows of the focal plane spot cast by the lens. When u...

Re: Problems with specular reflection and homogeneous volume

Ok yes that again helps getting to the bottom of things. A quick check reveal that 1.6 (using the experimental luxcore as I did before) defaults to bidir. 2.0 defaults to path. I hadn't put much thought now into the different raytracing approaches (I know caustics are handled better in some than oth...

Re: Problems with specular reflection and homogeneous volume

I did try your suggestion, but again that makes no difference. - I set up a clear and homegeneous volume - set world volume clear - Create a light, mirror and camera - Create a cube. Place mirror inside cube, light and camera a) outisde and b) inside cube. - assign clear volume to cube external, hom...

Re: Problems with specular reflection and homogeneous volume

ok, I just made some progress actually! Attached is a test file I set up to have something simple and from scratch. Only a light, mirror and camera (and a file size that can be uploaded...) After all, I just got it to work by choosing BiDir instead of path tracing. I remember trying that with v2.0 y...

Re: Problems with specular reflection and homogeneous volume

Unfortunately, that didn't work. Still the same image with v2.1beta3.
If i maually specify the camera volume also. If i select anything other than the world_volume the scattering disappears completely, so it seems to be auto-detecting it. Must be something else.

Re: Problems with specular reflection and homogeneous volume

Seems like the attachments go missing if there are two dots in the file name...
Should work now.

Problems with specular reflection and homogeneous volume

Hi, I've just recently installed the new LuxCoreRender 2.0. I was previously using 1.6 a bit, and there is one thing I can't seem to get working in 2.0. I also didn't find any info on this matter that helped me, so maybe someone here knows whats wrong. I'm trying to render the following setup: - One...
