I'm doing a tutorial right now, maybe someone here has done it too, where I am making a tornado. I have two differend cached fluid effects to make the tornado, one is the main funnel cloud section, the other is the dust cloud where the tornado meets the ground. There aren't any problems ith animating them, and they're cached fine. My problem is that when I render I get a wierd pixelated pattern where the two fluids overlap. If I render the two fluids separately they render fine, but rendered together doesn't look right. Furthermore, when I use IPR on a section of the rendered image everything comes out fine, but use it on the whole image and it has the pixelated look again. I'd rather not render the two fluids separately because i can see through the dust cloud fluid, if only slightly, and it needs to stay that way.
I feel like there's just one button I'm missing, what's going on?
