This seems pretty basic, but I can’t seem to track down how it’s done- or even if it’s possible.
I’m adding fireworks to a scene that has a fairly detailed hair-particle-feathered bird in it already, and Blender is really chugging with basic test animations. Since the same setup in a fresh scene animates in realtime (compared to 1.5ish fps in the bird scene) I assume Blender is spending a huge amount of processing power evaluating feather particles instead of focusing on the fireworks.
So the question:
Is there a way to tell Blender to ignore those feathers until render time? Or better yet, since the bird is completely static, to somehow bake them or turn off physics for them?
