Data Links
A new feature has been implemented to organize links of particle settings to data outside the settings data block, e.g.
- Objects (emitters, colliders, ...)
- Materials
- Textures
Problem with such links is that they
- prevent reuse of particle settings for different particle systems
- introduce unwanted dependencies of the particle settings to other data.
The solution is the introduction of Particle Link Slots. These slots are only placeholders for the actual data, which is assigned in the concrete particle systems. Image 4 shows the typical example of an object link being used for an emitter module.
