Short description of error
particles from a particle system emitted from particles via particle instance modifier get emitted in locations
quantized by frames.
A longer version - There is a particle system that emits objects containing particle systems through particle instance modifier (to my knowledge the only way to make particles constantly emit something in Blender - "shooting star" effect), resulting secondary emission is performed once per frame, clumping particles together. Subframes setting has no effect on this behavior. This is a problem when particle emission needs to form any sort of detailed patterns where particles are smaller than their emitter.
Exact steps for others to reproduce the error
- Play animation.
- On the left, particles generated by particles moving on the right get emitted in frame-by-frame clumps.
