There is no significant boost in simulation speed with enabled GPU support. Why?

The mesh is not created where the particles are. Why is there is an offset between mesh and particles?
There are some cases where you will see an offset between mesh and particles:
- The "Scene" tree object has been shifted with the the parented "Mesher" node after the particle simulation. To fix this, detach the "Mesher" or reset the "Scene" object to its original position.
- With some MoGraph objects ("Cloner", "Array", and "Matrix"), RealFlow | Cinema 4D evaluates transformations and applies them to the "Scene" and "Mesher" nodes. This may result in an offset.
Particles are not influenced through daemons or other fluid containers. What's happening?
In many cases, the links are established automatically by RealFlow | Cinema 4D, but there are also occasions where you have to connect interacting nodes.
Take a look the "Scene" and "Links" fields of the nodes involved:
- If "Scene" and/or "Links" are empty the node will not be affected by other scene elements.
- Specify the interacting nodes and "Scene" through drag and drop.
I have applied an object to the "Object" emitter, but there is no emission. What's wrong?
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 "Resolution" to create more particles. You may need very high settings (> 100 or more).

You can define a base path in Cinema 4D's preferences under "RealFlow". For the actual cache data we recommend specifying a separate folder for every scene, because otherwise existing data might be overwritten.

simulations in 2.0 as well?
Yes, this is possible, although a few fluid parameters have changed (e.g. PBD "Viscosity" is now "Damping", PBD "Ext Pressure" is now "Ext Pressure Scale"). We therefore recommend going through all fluid settings to see if they have been converted correctly.

1.0 scenes can be used with RealFlow | Cinema 4D 3, but there are a few things you have to consider:
- The RPC format for particles is no longer supported and cannot be loaded or processed. RealFlow | Cinema 4D now uses the Alembic format.
- Mesh Alembics are still valid and can be used with version 2.
- Initial states are no longer valid, because they are also stored in the old RPC format.
- Simulation settings from version 1 are set to "Auto".
- Simulations with the "Liquid - PBD" particle type will be slightly different due to new fluid parameters.
Why are the cache files so big?
