I’ve been playing with Fluid Simulator to spruce up this video:
There’s water pouring out of a trough at the beginning, and starting around 1:40 there’s a simulated creek.
For the pouring section: can anyone recommend a way to keep the stream more cohesive? I’d like it to look consistently like a “wall” of water. It looks correct part of the time (see around 0:09) but at other points the stream breaks up and has discontinuities. I want it to keep flowing quickly, but be less prone to separations in the pouring section. Is there any parameter that would do this?
For the creek section: this simulation had the following parameters:
- Preview Resolution: 100
- Final Resolution: 200
- Real World Size: 10.000
- Domain Size: ~1 Blender unit
Even though the resolution is maxed out, it still seems that I can see the shape of the mesh in the final render. The first scene used the same material, and rendered very smooth. Any thoughts on why this scene looks more polygonal? Is it true that the Subsurf modifier doesn’t have much effect on fluid meshes? (That’s what I thought I observed when I applied it to the mesh.) Is that because they’re triagonal? Or does it have an effect and I just couldn’t see it?
Also - I’d be interested if anyone has suggestions on other effects that could be added to tie the creek into the scene. I wondered about ways to do any of these:
- Caustics where the water runs onto the baseplate
- Light reflections onto the walls of the creek bed
- Transparency through the water showing the Legos underneath
Are any of these possible? What would the difficulty be? Do you think they’d add much to the look? Any other suggestions?
