Re: Realistic simulation of camera and laser

Opacity=1 is the default.
I should have said "you should leave it at 1" instead of "not use it".

What exactly do you mean by "like alpha" then?
Like transparency in an image manipulation program or a compositor.

Re: Realistic simulation of camera and laser

Opacity is a common property of all LuxCore materials, meaning it's not specific to glass.
It is a bit like alpha transparency.
If you want the glass to be physically correct, you should not use it.

I think FarbigeWelt meant "vanish" in the sense of "being transparent".

- no clamp of hard to render caustics (i.e. group of bright pixels), etc.
But aren't fireflies always hard to render caustics?
So the longer you render, the more caustic paths are found and eventually any single firefly develops into a clump.

Re: Problems with specular reflection and homogeneous volume

v2.0 contains a bug in the camera's volume auto detection, if I remember correctly.
You could use v2.1beta3 instead.
Or you have to specify the correct volume in the camera settings manually.

Path rendrer seems not work with well with heterogenous, scattering medium.
I did not encounter any problems yet, all my smoke renders were done with Path OpenCL.
Maybe your problems were caused by something else, e.g. the spotlights being not-intersectable light sources?

Re: Usability and Luxcore workflow streamlining ideas

I still cannot follow the request for an artistic sun. But if as Dade said sun gathers fireflies in the way of path render then sure there is a solution required like architectural glass. By the way, you can disable the sun's visibility to specular rays to get a similar effect (maybe disable glossy...
