Hi, i'm trying to create an animated texture with fluidTexture2D.
The goal is to have an effect like moving oil islands over a water surface.
Until now i used a fluidTexture2D, with
Density and Velocity on Dynamic Grid
Temperature and Fuel on Off(zero)
Color Method on Use Shading Color
Gravity 0
Viscosity 1
Friction 5
Damp 0.3
Density Scale 0.5
Density Buoyancy 5
Density Dissipation 0
Density Diffusion 0
Turbulence Strenght 4
Turbulence Frequency 200
Turbulence speed 0.2
Then i painted with Paint Fluids Tool inside the container in a spotty manner the Density to create the islands, instead the water is the space where there isn't any density.
Now if i playback the scene i see the islands moving around but the problem is that they loss consistence immediately while they're moving, until they vanish. And no matter which values i set for Density Buoyancy, Dissipation, Diffusion, or for Viscosity, Friction and Damp, they loss always consistence and i cannot find a way to make them conserve their shapes.
How can i do this? If it's possible, is it better if i use two differente kind of fluids inside the same container? Which are the attributes to change to solve my problem?
Thank you very much.
