Hi

It seems there is a bug with 3D particles and fog (we can see the 3D particles doesn't use the fog in the screenshot : )

Yep this is true with the 3D particles, they will glow through the fog regardless. Ugly but could use multiple emitters tied to your fog distance.

Hve you tried SetObjectFogMode() with the particles?

Hi


Thank for your answers

I have tried and it doesn't work, I think SetObjectFogMode() doesn't work with AppGameKit 3D particle.
(If I create my own system of particles, of course, it works, but I would like to use the AppGameKit particle system)

Do you mean changing the transparency with fog distance for example ?

For example you can have a second emitter with the color set to match your fog. Then check the distance from the camera to the emitter and when it reaches the distance set with SetFogRange(125, 200) then you can "turn off" your regular emitter with Set3DParticlesMax(emitterID, 1) and "turn on" the fog emitter with Set3DParticlesMax(emitterID, -1). This method would allow the regular particles to dissipate and get replaced with fog so the effect may not be that bad (wasn't worth level of effort in my case.)

Just sucks to have that extra watcher but I believe the particles are generated via graphics chip so the engine may not have the ability to super-impose the fog over the particles.

Very clever!
