Hello. I've been trying to understand cops more lately and seem ran into a bit of a problem. I want to render out an object and change it's color in cops(in this case a white sphere to a blue sphere). This seems to work when the diffuse limit is 0, but when I raise it, the color looks a slightly different. Can anyone help me understand why this is happening and how to fix it? Thank you.

Here is an image of the object rendered out with a blue material

Hello, I've been studying this webinar on flip fluids and seem to have run into a bit of a problem.

Whenever I try using the dual rest solver vop to create uvs, nothing seems to happen. No matter what parameters I adjust, the uvs just end up at 0. I even downloaded the example files and the method still doesn't seem to do anything. Has the workflow for this type of thing changed since this webinar was created or am I just missing something obvious? Thank you.

Hello,

I've been watching a lot of fire videos lately and I came across a particularly interesting one a few days ago.

I was really interested in the pool fires that are shown at roughly 4:52 - 5:40, but I'm kind of at a loss for how to even begin making something similar. I assume that I would want to animate the fuel source and gas release to create the puffing look, but I'm not really sure of the best way to make the fire get sucked in toward the center. Does anyone have any ideas for a way to approach something like this? Thank you.
