This is a little idea I had rolling in my head, with regard to particles
- With Advanced particle settings enabled, a new option could be added
to the Emission shelf (is that the right term?), under the Number
entry. The new option would be Adaptive Emission.
- When Adaptive Emission is enabled, it dynamically determines how many
particles to emit, based on the Particles per Face setting. As opposed
to the current behavior, where it will try to fit in any leftover particles.
- Additionally, a Particles-to-Distance setting can be added. It would
override Particles/Face and instead make the system emit a particles
spaced out by X blender units.
- The emission Number setting would still be used, and instead would
serve as a maximum limit on the number of particles.
- Going into Particle Edit mode and making changes will, of course,
prevent the adaptive emission from adding or removing any further particles
- Makes it so that the particles/face setting guarantees a specific
number of particles (in case that is important to the artist)
- Makes particle systems more reusable by allowing them to adapt their
particle counts to the emitter mesh, instead of creating multiple
variants of a particle system for each mesh it gets used on. Useful for
when particles are used for "splatting" meshes onto a scene, such as
trees, shrubs, rocks, or the buildings in a city (the latter of which
