Firstly, apologies for what maybe a stupid question......

Whilst trying to get particles to rotate at a constant but per particle based speed which seems to be a tricky one i came across a compound to randomise the emission orientation. The manuals are as usual devoid of any sensible explanations so i’m wondering if it makes perfect sence to anyone here.

Firsty i’m not entirely sure where the cone comes into it, although fiddling with the “cone_axis” parameter seems to set the initial y axis (i think). And the twist min and max seems to rotate the particle arouind its y axis (i think), but then theres the start and end angle which i’m assuming relates in some way to the cone that i’m not grasping.

Any clues?

Also on a broader scale which is how i’m stuck - i want to emit a particle with a random orientation that spins on its’ x axis for example with a rotation speed that decreases over particle age OR emit a particle without tweaking the emission orientation and have it spin on a random axis (not changing over time) with a rotation speed that decreases over particle age - how would you go about it. My maths is rubbish and my approach is trial and error which only works when i can interpret the results (which sadly in the case of “start and end angle “) i can’t.

Cheers,

First the particles are spun around the axis and then tilted by an angle.
Min angle is the minimum angle the particles get tilted. Every particle has to rotate at least that much. Max angle is of course the max amount of tilt they are getting.

for the spinning effect you could use the spin particle compound and control the rate over time.
