Hi Jan,

this one looks really very strange...

Shall I open an issue on github?
At the moment this thread seems to be lost among all thoser other topics.

Once more congratulations for your test scene - it really shows beauty of light.

With kind regards.

Hi lighting_freak,

Shall I open an issue on github?

Yes you may try. The Materials are: Working and Working001. Working001 is just a Copy of Working but they seem to behave differently to light.

However I'm not sure if it will be accepted as a bug. After some further thinking I think maybe LuxCore rules for Internal and External Volumes are violated. Maybe only One Shared External Volume is allowed. For Internal Volume maybe no such limits as long Light Rays are exiting back to this Shared External Volume? Hope to hear from the developer.

Once more congratulations for your test scene - it really shows beauty of light.

Thanks and this is one important feature that I wish will be incorporated. Many rays of light not just one single line of laser that can be enabled in Solid Preview. :idea: It can greatly assist in learning and problem solving.

Best Regards

To the developers - please take this thread serious, don't forget about the slogans on web page.
