Maya 2020 fundamentals - modelling the real world
Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

Hopefully simple question regarding Fluids (Hard surface)

Hello all.

I have an issue that has been kicking me around for about 2 weeks. If you have seen the demo from Duncan regarding the mixing of differently colored fluids, you know what I'm trying to do.

I am trying to demonstrate one fluid being diluted by another fluid. The problem I am having is that my fluids are turning grey. Nice bright vivid colors at emission, but they get muddy and desaturated as time goes on, turning almost completely grey.

I think the issue has something to do with density. His fluid (before hard surface) was pretty tight and opaque. Mine is not.

Any help you can provide is really appreciated.

I attached my scene if it helps.

My dynamics knowledge is quite limited but I fiddled with this and increasing the "color diffusion" attribute seems to help. Its under the shape tab, in the color subsection of content details section.

Hi Genny, thanks for your reply.
Are you using Maya 2011? I don't see the attributes you are talking about. I am using 2012.

Aaah. I must have been drinking. For some reason your reference to the shape tab threw me off.

I like how it gets rid of the grey, but can I bring back some brightness, or just do that in post?

Thank you.
