I'm trying to model a physically based version of the Utah teapot. The teapot has fluid inside it, which is modeled as a closed manifold:
I'm trying to add a meniscus to the liquid. I have also modeled these as closed manifolds:
I apply two boolean union operators to join the three together and make a single manifold surface. However, the result still has geometry inside:
Here is my file. The fluid (layer 2, active) is unioned with the meniscuses (layer 10+2). Note: there is an intersection operator also, which is irrelevant (I can flatten it and the checks below are still true).
I have tried:
- Cleaning any dead geometry and searching for any non-manifold geometry in all three objects (none, so manifold).
- Recalculating the normals of the meniscus and fluid.
- Inspecting the normals of the meniscus and fluid and confirming they make sense. As many other questions of this ilk had this as a problem, I checked it thoroughly.
- Setting smooth or flat shading.
- Only doing one meniscus.
- Triangulating everything first.
- Moving the meniscus up/down to see if it's a precision problem.
