Can you tell me what is the current solution (State of art) to have a special effects (probably with transparency) and the fog.
How AAA games are dealing with this problem.
I’m not sure exactly what you’re asking. The state of the art here is the same as 20 years ago. Hasn’t really changed, apart from the complexity of the fog calculations.
So bugs with fog + transparency are still present, and not solved in any engine ?
Again, what exactly are you asking about? Most games there are no problems with fog on transparency.
There are problems with transparency sorting, which fog can make more obvious, but that’s different.
I have experimented a little more and it looks like not all transparency shaders looks buggy.
Particle->StandardUnlit looks bad but some other transparent shaders are ok.
I’m going to test it for a while.
Take a look at the image. In front is the plane with Transparent shader, in the back are some transparent windows on building.
Ah, yeah. That specific shader is broken. Unfortunately it always applies the fog color as if it’s a solid black, which is correct when it’s using the Additive Rendering Mode, and wrong for everything else. It’s unfortunate too since the shaders it replaced (and which are no longer included with the editor) worked perfectly. I don’t think I noticed this one was broken since there are several other issues with those shaders, so I never use them myself.
