Re: highlight compression

The problem with reinhard is that it's auto-adapting to the image brightness, leading to confusing behaviour like described here: https://wiki.luxcorerender.org/BlendLuxCore_FAQ#When_I_change_the_brightness_of_my_lamp.2C_nothing_happens When I change the brightness of my lamp, nothing happens You ar...

Re: sharing renders and files

It's preferrable to upload images directly to the forum instead of using external hosters (otherwise images might expire at some time and old conversations can become hard to understand without the images).

Re: Light emitting instances

One thing I'm wondering about is:
Is the slow speed caused by every triangle being a separate light source?
Would it speed things up to group all triangles of a light-emitting mesh into being one light source? And is that practical?

Re: Light emitting instances

LuxCore seems to be doing some very time-consuming preprocessing on meshlights, which becomes noticeable even at low polygon counts.
It could be worth checking if this could be avoided or accelerated in the LuxCore code.

Re: LuxCore on Felix Render implementation

I'm not very familar about how light groups work in Luxcore Each light group creates an RGB output buffer where the contributions of all lights in the group are stored. Here are the SDL details: https://wiki.luxcorerender.org/LuxCore_SDL_Reference_Manual_v2.5#Radiance_Group By summing all light gro...

I managed to reproduce the problem, it happens when i hit z choose material preview then choose rendered viewport and finally choose solid viewport, the cpu usage remains at 100%.
Nice, I tested it 3 times and it has reproduced the issue each time. Thanks, that helps a lot.

Re: Viewport render issue

The problem mentioned in the OP and experienced by me does not involve any crashes.
So KintuX and TAO, you might be describing different issues.
