creating a dust shader

[cspears2002]

Hi!

I'm working on a personal project that simulates something burrowing under a brick road. As the bricks are displaced, dust is generated. My problem is I can hardly see the dust! I am currently using a shader I found in an old 3d Buzz tutorial (the tornado series). Can someone give me some advice on creating a good dust shader? I attached the scene file.

Thanks!

this is a tut from miguel which makes a nice smoky look, could tweak it to dust.

Thanks for the info! I think this shader could be modified to make dust. However, I do have one question. Miguel's meteor creates a nice steady stream of debris. Unfortunately, mine doesn't do that. I see spaces in the debris next to the meteor. Any idea how I can fix this? I tried reducing the drag but that didn't help. Thanks.

hey, I took a look at your scene. I changed the sphere from primitive to polygon mesh, and on your source node in the popnet I changed the emission type to: surfaces random. This seems to fix the problem somewhat. If it's not good enough for you you might want to try oversampling.
