Help Obi Fluid Not Working with Transparent Glass

[josemendez]

Yes, let me be clear ("does not show the fluid behavior"):

1. You provided a video — on this thread — showing 'scaling down the faucet'. But the video does not show rendered liquid, or filling the glass, and when I do this, it is *not* the same effect — water gets 'clumpy', jumps around in the glass / won't settle, OR kills the frame rate

2. Have tried all suggestions about scaling the Solver, boosting the Resolution, lowering Surface Tension, and none worked to fix these problems. There are *so many* settings, maybe we are doing it wrong, but we have tried *for hours* without success

3. You write "it's the exact same behavior at any resolution" but then leave it to your customers to figure out — unfortunately, we are not seeing these "exact same" results

4. A page that should show a solution is blank: http://obi.virtualmethodstudio.com/tutor...space.html

So this is the request —

Please provide a demo Scene (or scenes) of water pouring into a cup (not a "bowl" as in the faucet demo) at normal scale

Everyone on this thread is asking for the same thing.

Will you be able to provide more actual demonstrations, for benefit of your customers?

Hi,

1.- Rendering the fluid surface is not part of the simulation, it generates a surface from scratch at the end of each frame using ellipsoid splatting. So enabling/disabling the fluid renderer does not (in fact, cannot) have any effect whatsoever on the physical behavior of the fluid.

2.- I haven't been able to reproduce *any* of the issues you describe above when using any of the solutions in this thread. Tomorrow I will record videos and provide samples using smaller resolutions as you ask.

3.- There's nothing to figure out. Simply change the fluid resolution parameter, behavior is guaranteed to be the same (finer, or coarser looking, but overall the same).

4.- That page does not exist. If using Obi 4.X, try:

If using 5.X, all simulations are performed in local space by design (as described here: http://obi.virtualmethodstudio.com/tutor...olver.html) so scaling the solver down will just work.
