Particles will be created in all areas of the bitmap/shader; only purely black areas remain empty. Greyscales are treated like purely white pixels (= full emission). RealFlow | Cinema 4D only evaluates the red channel of a texture. |
Object Emitter
The "Object" emitter also provides a "Bitmap" field, and the workflow to attach the image is the same as above. Anyway, there are a few things to know:
- This emitter creates particles from the surface of an object.
- In order to control surface emission through a map, the object has to be made editable and requires an "UVW" tag.
- RealFlow | Cinema 4D can only take the UVWs it gets from the tag.
- If there are just a few or no particles at all we recommend increasing the fluid container's → "Resolution" parameter, because it defines a particle's radius. If a polygon is smaller than a particle emission is not possible.
