Every Maya object has a "RealFlow | Maya" section in the "Attribute Editor", and here you control how RealFlow | Maya "sees" an object.
Add Collider
When you click on this button RealFlow | Maya will add a → "Collider" element to the object, where it is possible to define the object's physical properties like friction, stickiness, or bounciness.
...
- The offset can be visualized with Collider > Display > Show Collision Geometry
- Both positive Positive and negative values are accepted.
- To control this parameter manually, disable "Auto Surface Offset".
...
Here are the three possible modes – you can read more about this topic under → "Adding Objects" and → "Filling Objects".:
- "Solid inside" makes the fluid collide with object's outer surface.
- "Solid outside" creates a hollow object and the fluid interacts with the inner surface.
- "Shell" is normally used with open objects like glasses, vases, but also planes. When active, an invisible layer is added around the object's surface. The thickness of this layer is
Cell size * 3. As a consequence, there will always be a gap between the fluid and the object.
By default, "Volume Mode" is determined automatically by analyzing the object's geometry, but this test is not always reliable. For manual control uncheck "Auto Volume Mode". If you can see leaking particles in conjunction with thin or single-walled objects please consider activating → "Continuous Collision Detection" in the "Collider" element.
