[Solved] Particle Emitters 2 spawning in a square-shaped pattern.

[Yours Truly]

Hey there.

I'm having some slight issues with the way particles are spawning. They appear in a square radius.

How do I make it so that it spawns in a spherical or circle radius?

There's a way, but with only rotations.

As JAKEZINC already said, you can rotate the emitter. Here are some examples of a global sequence that uses simple linear clockwise rotation:

Around the X axis
0: { 0, 0, 0, 1 }
200: { 0.707107, 0, 0, -0.707107 }
400: { -1, 0, 0, 0 }
600: { 0.707107, 0, 0, 0.707107 }
800: { 0, 0, 0, -1 }

Around the Y axis
0: { 0, 0, 0, 1 }
200: { 0, 0.707107, 0, -0.707107 }
400: { 0, -1, 0, 0 }
600: { 0, 0.707107, 0, 0.707107 }
800: { 0, 0, 0, -1 }

Around the Z axis (this is probably the one you need since the "surface" of the particle emitter is always initially parallel to the XY grid)
0: { 0, 0, 0, 1 }
200: { 0, 0, 0.707107, -0.707107 }
400: { 0, 0, -1, 0 }
600: { 0, 0, 0.707107, 0.707107 }
800: { 0, 0, 0, -1 }

Rotation in the examples above looks like this:
0 - 0 degrees
200 - 90 degrees
400 - 180 degrees
600 - 270 degrees
800 - 360/0 degrees

As you can see, rotations need to have a key every 90 degrees or less. These examples use a global sequence with a duration of 800 frames, but you should change it depending on how fast you want the emitter to rotate.

Thank you both for the solution. Thread solved.
