noise flickering in clouds - aldred2 - 01-16-2007 Hi I'm doing a cloud flythrough but getting some pretty nasty flickering. Here's a sample .... http://www.digikoku.com/download/070116 ... er_001.mov Nothing is animated, but the noise is moving. I don't think it's an antialiasing problem. The camera is moving through stationary particles. What could it be? Thanks Mark - sitnisati - 01-16-2007 The problem is in too big step size, so sampling sometimes hit noise and sometimes does not. Try to decrease step size and problem should go away. Kresimir - aldred2 - 01-16-2007 Thanks. That seems to have fixed the flickering. There's another problem. When the camera moves through a particle I'm getting vertical lines in the image as below. What could this be? Thanks Mark - sitnisati - 01-16-2007 It is hard to tell what this vertical line is, but I hope that we're going to find out. Can you tell me what renderer do you use ? Is this line still there is you use Scanline renerer ? Thanks Kresimir - aldred2 - 01-16-2007 Hi Kresimir It's the FinalRender fisheye camera. But I'm getting the same line in scanline too. I'll send the file if you like. Thanks Mark - sitnisati - 01-17-2007 Hi Mark, Please send me a scene so that we can take a look at it (mailtoupport@afterworks.com). Thank you. Kresimir - aldred2 - 01-17-2007 Thanks. I just sent a sample. I forgot to mention, I'm using Afterburn 3.2a in max8 sp3. Thanks Mark
