With PLA-enabled objects, RealFlow | Cinema 4D has to recalculate the internal collision geometry with every single simulation step. Especially with small → "Cell Size" values PLA might be a simulation's bottleneck.
I can see particles going through my collision object. What

's happening here?
With fast moving particles and/or a very small number of simulation steps per frame it might happen that a particle in a starting position goes to a final position in the next simulation step that is at the other side of the collision geometry:
- To avoid this, activate the "Collider" tag's → "Continuous Collision Detection".
- By default the auto mode is enabled, and RealFlow | Cinema 4D will decide automatically, if the collision object requires "Continuous Collision Detection".
- Collision detection is computationally more intensive, and simulation simulations take longer.
- In some cases the automatic detection fails, and you have to disable enable "Continuous Collision Detection" manually.

When the body's polygons are very small it might happen that you will not get any particle emission. To fix this, increase the "Fluid" container's → s "Resolution" parameter to create more particles. You may need high settings (100, 200 or even more).
Are RealFlow | Cinema 4D particles able to influence Cinema 4D dynamic bodies (rigid and soft bodies, cloth)?
No, RealFlow | Cinema 4D do does not change the motion or shape of Cinema 4D dynamic bodies, but they are able to interact with them in terms of collisioncollide.
