Rendering Pyro

Recommended Posts

Hello there!

I am currently at a stage of rendering my pyro simulations and I am getting lots of flickering! I used a 1024 depth map shadow and its already taking so long. I am on Ubuntu with 4 gbs of ram.. and my renders always crash the first time at an unknown varied frame so I have to sit beside my computer to keep watch.

Can someone give me any tips on rendering smoke using the pyro shader???

I know I'm not answering the question here but: have you tried using the "basic Smoke" shader ?

Are you sure the flickering is from the shadow map and not from the noise in the shader? If the issue is from the shadow maps try a lower resolution map with a little blur (like .01).

I haven't tried the basic smoke shader yet... I was following the tutorial on cmiVFX on creating smoke and dust effect.

Could you explain further on how lowering the resolution of the depth map will produce less flicking? I don't really understand..

use billow smoke shader , easier to debug . If your not familiar with the pyro shader , it can be a bit overwhelming ;) . If your going to use shader noise, make sure your rest field in the sim is set to a long enough reset rate that your render wont pop, as the billow smoke isn't set up for dual rest fields.

Ive never seen significant shadow map flickering , even with 512 maps. Veiw through light to make sure your not wasting any shadowmap space..

Would it be possible for you to post your hip file, or a stripped down version of it so we can see the problem?

Cheers
