hi. is faster, let's say, generate particles or use footage of particles if possible, rendering-wise? on same matter hidden layers still rendered? and third, if direct me link recommendations optimizing export/rendering, grateful. is faster, let's say, generate particles or use footage of particles if possible, rendering-wise? depends on number of particles talking , how generated. of course particle systems can slow, can using pre-existing footage, scaling, keying, retiming , recoloring it. comes down concrete settings , effects used. beyond it's merely matter of actualyl trying simulate , how effort takes. on same matter hidden layers still rendered? ae self-optimizing , skip on hidden layers, layer 0% opacity , layers outside comp. how works of course still depends on teh actual structure of comp. peopel have wondered strangest things because thought 0.001% opacity same zero, not. being thorough, diligent , careful helps. and third, if direct me link recommendations op...
