Re: Pool test scene

The absorption looks stronger in that image. Are all the values being kept the same? Also, with the old Lux image, the refraction doesn't look as strong.

Re: Pool test scene

Try using the path engine with metropolis sampler. In my experience, this is the best method for rendering SDS caustics such as this.

Re: BIDIRVMCPU

There is very little info about the engine at all. Could you tell me what units the start radius scale are in (bidirvm.startradius.scale)? Would it be possible for it to be in screen space pixels?

BIDIRVMCPU

Is there anything planned for the BIDIRVMCPU renderer, such as use with Blendluxcore or improvements to the engine, or will it stay as is?

BiDir can not render SDS path at all, you need BiDir with Vertex Merging for SDS paths.
If Bidir cannot render SDS at all, then what is my image showing?

Re: Weak Caustics with BiDir, Path Caustics ok

I also have this problem when using HDRIs. But what is strange is that SDS caustics, which are meant to be hard for even the MLT sampler to render, clearly show in the image but no regular caustics. In layman's terms: caustics in reflections/refractions, but no caustics on directly in view diffuse s...

Is the Bidir engine planned to support GPU/OpenCL?

Re: LuxCoreRender v2.0beta3 released

Pressing Ctrl-Z seems to delete all of my material nodes for all materials. This isn't normal, is it? :? No. Can you open an issue about it , describe in more detail what you did, if it is reproducible, and post an example scene that shows the problem? The issue isn't scene or context specific. If ...
