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).

Several hundreds of thousands of particles are absolutely normal and can be simulated very fast with Dyverso's → GPU options. Even several millions of particles are not problematic and often required for mid-scale scenes.
I see exploding particles when they interact with objects, for example when I try to fill a glass. What's going on?
RealFlow | Maya works with adaptive substeps by default and this means that RealFlow determines the actual number of substeps. When particles settle, the number of substeps decreases, and this means less precision. As a consequence physical effects inside the fluid start to accumulate until a "pop" occurs. After the explosion the particles settle again, and RealFlow increases the number of substeps - the beginning of a new cycle. To avoid this effect increase the number of → "Min Substeps" and/or → "Min Iterations".
