Issues with particles editing using OBI Editor

[josemendez]

There's a big misunderstanding here. You can't "add" new particles. Particles are automatically generated when you click the "Generate" button, distributed using the parameters you set in the blueprint. Then you can only optimize out certain particles, in case you only want particles in specific areas of the mesh.

The 3 mode buttons (paint, add, smooth) in the property painting brush let you paint properties on your existing particles. In the screenshot, you're adding mass at a rate of 2 kg/second to your existing particles, not creating new particles. See the manual for details:

In property painting mode, you can use brush tools to paint particle properties directly on the surface of the softbody. Enabling the mesh render mode is recommended to work when painting.

Most properties offer 3 brush modes:

Paint:
Displaces the current property values towards the one set in the proprerty field. The brush opacity determines the speed at which the values shift towards the target one.

Add:
Adds the value set in the property field to the property values in the mesh. Again, the brush opacity determines the speed at which the values are changed. You can hold shift in the keyboard to subtract instead of add.

Smooth:
Smooths out the property values.
