Caustics not showing up(very faint) when baking

Post by a-n-d-r-e-w »

Does anyone have an idea of how to get the baked caustics to match to how they are in the render? The second image is a bake of the floor plane but I can’t seem to get the caustics to show up. Using: CPU Path / Light Tracing / Caustic Light Cache. Thank you.

LuxCore baking support (https://sketchfab.com/3d-models/luxcore ... bff3cffdec) is not available in BlendLuxCore. It can be used only by directly using LuxCore scene files, etc.

I have the feeling you are just baking with Cycles. Or are you using directly BAKECPU render engine :?:

I'm using LuxCoreUI, I exported a scene out from blender to use with LuxCoreUI and I am using BAKECPU. The second screenshot is a baked image, its just the caustics are not really showing up like in the render which is using the same settings except using the PATHCPU engine for the first screenshot. It looks like when it is baking it is using the look of RTPATHCPU.

Ok, good. Can you post your test scene (.cfg, .scn, etc.) so I can (probably) fix it ?

It was a regression in the latest sources and I should have fixed the problem:

The upcoming automatic build will include this fix: viewtopic.php?f=9&t=736

Ok Great! Thank you for taking the time to look at it, I’m somewhat new to Luxcore so thought I was just missing a setting.
