Reflections in ligth tracing

Post by JulianoLisboa » Thu Mar 04, 2021 5:52 pm

hello watching tutorial from the Index_3D channel. Initially made for octane I remade it in luxcore, at that moment I had some doubts.
As a joke I also made a frame in the cycles and noticed that some reflections of the glass appear just like the Bidir of Luxcore, but they do not appear in the Ligth Tracing of lux. I imagined that the cycles should not appear and in all modes of the luxcore the reflection should be apparent.

What LuxCore version are you using ? And have you changed the default path and light tracing max. depths ?

Version 2.5 RC. Yes, I changed it to 12 on the specular.

But for Path+Light tracing there are 2 parameters, did you changed both (or BlendLuxCore does) ?

Good morning friend, I reviewed the whole scene and found that when I switched from bidir to ligth tracing the values of light tracing max. depths have been reset to the default. So it is not a mistake by luxcore in rendering, but it did not keep the values set in the change.
