Re: Re:Strange effect using volume, CPU BiDir

Yes, and as you can see, beam above spot of second spot light is not visible. It seems for me, light passing homogenous, scattering volume keeps scattering outside the volume. I guess I'm done with my research on that matter. Air in your scene is not so dusty, that's why beam from second spot is ba...

Re: Test scences GPU Path vs CPU BiDir

The beam that should not be Did you also change the camera volume? Nope. It was Air and I changed Air volume itself. Nevermind that. I experimented with beam disappearence and submerged everything in box of dust, changed external volume to that dust, then removed dust and forgot abot external volum...

Re: Test scences GPU Path vs CPU BiDir

Maybe I forgot dust somewhere though.

Re: Re:Strange effect using volume, CPU BiDir

Yes, and as you can see, beam above spot of second spot light is not visible. I think there is a beam. Your dust is just too thin. The reason why you have brighter beam above glass is that there's another beam going up, reflected from glass and wine. I tried it with laser, it gives more evident bea...

Re: Strange effect using volume, CPU BiDir

What is wrong with this scene and objects? - some of your materials have incorrect interior/exterior volume settings (e.g. the "MatteWhite" material has no exterior volume specified, it should be set to "Air"). I have a question about volumes: shouldn't it World Volume be used w...

Re: Bidirectional strange with glossy material

What is specifically wrong in my setup? I guess you have layers 1 and 2 enabled? Your mirror material does not have an exterior volume specified (should be set to dust_volume). Ha! That's how it works. Thank you! Looks to me like some magic, though. What I thought was that volumes just work because...

Re: Bidirectional strange with glossy material

Red beam emitter is inside the scattering volume and it behaves funny. Green beam emitter is outside the volume and behaves well. Weird behaviour of light beams and volumes is almost always caused by incorrect settings. We should probably make an in-depth tutorial and/or add warnings or tips to the...

Re: Bidirectional strange with glossy material

Try setting the camera volume to the same you used as the world volume. I'm a bit lost, as this fixed the problem (it should) ? That did not fixed the problem, but I've found what it is. Red beam emitter is inside the scattering volume and it behaves funny. Green beam emitter is outside the volume ...

Re: Bidirectional strange with glossy material

I have now decided to use pure glass for my analysis of the light path. For complex materials, I could get unforeseen effects. Pure glass is better for my purposes. In the example, there is a container with water in it (you can not see it, it's pure glass and water) and the laser comes from the lef...
