3rd impression: Scattering volumes and Light beams

In contrast to BiDir, openCL path hybrid (path plus light tracking) laser beams are not visible consistently. Unexpected is that the bright lines on the rough glass is only visible with the two separated glass objects and is not visible for the other glass objects, the overlapping ones. Also in cont...

2nd impression: Scattering volumes and Light beams

After a dozen different set ups I found a solution close to what I wanted to illustrate. Aside of that it is the best looking image from a series of attempts. Scattered Laser, 2, Glass rough materials, BiDir, 5600 samples, OIDN 0.9, zooms.png There are three parts as described in the former post. Ar...

Re: Relaxing corner

Yes I know, but It's hard to find correct gain, lamps are 0,05, hdri is 1 in this scene; also I tried to change more darkness hdri color. My personal opinion, cycles is more immediatly to find light setup with different lamps. You should not look at the numbers, e.g. sun ~10^4 times brighter than a...

Re: BlendLuxCore Development

If anybody ever should ask again what advatages BlendLuxCore has versus Cycles the answer is load a Cycles scene switch to LuxCore and render the scene. Thanks to B.Y.O.B‘s efforts everyone can convince itself instantly.

Thank's BYOB for your suggestion.
... it's hard to balance hdri and other lights.

Why? Do you not use live view render (shift+z)? After a few seconds you should be able to guess influence of light setting.

Hi,

this is the result with half resultion and doubled samples:

The overall quality should is raised regarding noise - but the problem remain!

You said, render on CPU only. Is it BiDir? Do you use Metropolis? Have you tried Random? Avoid Sobol in your case.

1st impression: Scattering volumes and Light beams

Left: There is a intended gap between the two objects made from Glass-Null mix material of IOR 1.5 and 2.4.2. Middle: The red object overlaps the blue slightly. Right: The red objects overlaps the blue mostly. The Right shows a strange effect like objects are mixed instead of overlapped. (All surfac...

Re: AMD Ryzen 9 3900X

Isn't this due to poor opencl Driver ? Rx 5700xt = 9.75 TFLOPs Rx 580 = 5.3 TFLOPS Yes, looks like. I‘ve posted a quote too https://forums.luxcorerender.org/viewtopic.php?f=10&t=1219 9.75 TFLOPS is peak performance, high duty is rather 9.0 TFLOPS. According to data sheet, LuxMark 3.1 benchmark shou...

AMD Radeon 5700XT not ready yet?

Currently AMD Radeon 5700XT performs on level of 4 years old card R9 390x in Luxmark 3.1 Hotel hall benchmark. In theory the card should be about twice as fast but openCL driver is not ready yet what leads too low performance and other issues, see following or similar reviews. STH AMD Radeon RX 5700...

Scattering volumes and Light beams

Before I can post some visualizations I have their quality in the way my observations are clearly visible. Setup World and camera volume is clear with IOR of air. External volumes depend on objects‘ positions. The volumes are clear or homogeneous. Internal volumes depend on objects‘ purpose. The vol...
