blendluxcore_v2.8alpha1

Great! Thanks to Sharlybg who shared the information LuxCore runs in Blender 4.0 now I installed BlendLuxCore_v2.8alpha1 on my M1 MacBook Air 16 GB. And YES LuxCoreRender runs in Blender 4.0.2 Intel on my Mac. But not for long. As soon I saved a file with default cube set to material "Glass&quo...

Re: Dispersion of Laser looks odd

The behavior keeps strange. The Lasers faints above an Object made from Glass. Cornell Box_8, fainting Laser.png Even with a simple Object as a ring made from Glass. There are also strange caustics. Cornell Box_9, fainting Laser.png It dons't matter what kind of Exterior Volume. Non scattering Homog...

Re: Dispersion of Laser looks odd

Have you tried rendering it with LuxCore's BidirVM integrator and Metropolis sampling? Vertex merging would be a good fit for this scene. How do I export a Blender Scene for LuxCore? EDIT: Render Properties>LuxCore Tools>check LuxCore Filesaver, Text plus Path of Directory Load .cfg file in With En...

Re: Dispersion of Laser looks odd

Cornell Box_5, bidir, metropolis.png Cornell Box_5, path, light tracing, sobol.png As one can see there are differences between BiDir and Path Rendering. With BiDir the orange juice looks like orange juice but with Path it doesn't. What both algorithms fail is to render scattered lights behind Glas...

Cornell Box with Glasses

I think a lot of question repeat about Glasses and Homo- or Heterogeneous Volumes. A most tricky one, rendering an orange juice even required user with lots of experience to solve the question. For the simplicity I attached here a Bender with a special Cornell Box containing a Glass of wine and one ...

Re: Dispersion of Laser looks odd

Cone Light with Laser, volumes wrong.png There is a further issue. Look at the right border of the picture. The picture doesn't fit correctly there is border because the picture shifts some pixels to the right after rendering. EDIT: After setup a new Blender file by appending Objects in a new Scene...

The different volumes have defined priorities,.e. g. volume air 0 and volume homogenous 10. But the priorities of the volumes seem not working properly. For ...
