I have two different particles, the first one is fire (near the camera) and the other one is black smoke (far away from the camera).

When I look at the fire which is near the camera, the fire begin to clip and I can see the smoke instead of the fire, even the fire is closer (I should see the fire since its depth is much closer).

Here is what I have in my Shader technique:

ALPHABLENDENABLE        = TRUE;
SRCBLEND                = SRCALPHA;
DESTBLEND               = INVSRCALPHA;
ZWRITEENABLE            = FALSE;
ZENABLE                 = TRUE;
VertexShader            = compile vs_3_0 VSProgram();
PixelShader             = compile ps_3_0 PSProgram();

How to fix that?

@MJP: I'm rendering all the particles belonging to the same texture with one draw call.

So If I have 4 emitters using one texture and 6 emitters using another texture, for performance, I render the 4 with one draw call and the 6 with another draw call.

How do I fix that problem while I still render the 10 emitters with only 2 draw calls?

Another problem:

Lets say I have the fire close to the camera and the smoke far away from the camera, the smoke generate and then it move towards the camera (becoming closer than the fire)

In that case I would have a problem, I won't see the smoke since I'm sorting according to the distance of emitters (The smoke emitter depth is far but the smoke particles depth became closer than the fire when they moved)

Thanks MJP

One last depth problem:

When I disable soft particles, the particles appears in front of the camera ALL THE TIME even if they are very far away and I have many buildings much closer, I can still see the particles (while I shouldn't).
