Sun burst rotation

Hey folks,
I am currently trying to get a rotating sun burst going, something like this:

which rotates around the z axis.

What I did so far, was converting a circle to particles and instancing a grid at these particles. To rotate, I know I have to somehow use the x and y coordinates but somehow I just can’t wrap my head around it … If I only use one coordinate, it’s perfectly fine for half of the circle, and then spins back. I tried a Limiter on the other coordinate and than somehow multiply it but … well …

Any suggestions or hints to the right link/tutorial are welcome



Pull this apart and see if it gives you some ideas:

Thanks, that solved the issue! :slight_smile:

Is this the same result: Circle SOP set to Sliced Arcs, to two Delete SOPs set to pattern (of which one is set to Delete Non-Selected), then each Delete SOP to a Point SOP to color it, then both to a Merge SOP.
