I'll improve this for next SDK

For best performance of many particles please use new class 'RawParticles' in the next SDK (btw. your video with water is awesome!)
also you can disable D.softParticles

Thanks! (The best part about our implementation is that its extremely scalable)

I'll try it out RawParticles.

I'm uploading the SDK, will be available in few minutes.

Ah wow this is really really amazing!!! Getting 50fps @ 1 million particles @ 1080p which is great for increasing our particle sim densities. Thank you so much!

looking forward to seeing final version of your water simulation program

@llynx Where can I find that video?

Its not public atm.

How do you draw particles over a refraction shaded mesh? RawParticles.draw() after getting the backbuffer/setting the shader makes it so that particles are not drawn wherever the mesh is, while drawing before causes the backbuffer to include the particles in the shader texture.

Ah ok

what order of drawing are you interested?
1. mesh
2. getbackbuffer
3. particles
?

Yes, just that.

I draw the mesh, get the back buffer, set the shader, then draw the particles but the particles are not drawn over the mesh. (But they are drawn properly on screenspace that is not the shaded mesh)

probably the mesh outputs the depth, so particles are clipped.
how are you drawing the mesh?
test_blend_light material techniques modify depth, others shouldn't

My setup is similar to the refraction shader tutorial. If you draw alpha particles in the refraction shader tutorial you get the same issue when the particles are in front of the refracted material.

I found how to make this work. (For future reference if anyone needs to draw alpha particles over refracted meshes)

How are these RawParticles supposed to be used exactly? Can someone throw a quick sample?
