Rotation Angles in Niagara scratchpad

Development Asset Creation FX
1

Hi,

I’m new to Unreal and Niagara system. Trying to understand logic behind undocumented(?) nodes.

I wanted to do a simple rotation inside scratchpad on the Particle Spawn (just after the initialise Particle, no other modules present), using “Rotate Angle on Axis” (which i guess it means “Rotate Vector along Angle/Axis”).

It looks like this node is expecting angle not within the industry standard, radians (0-6.283) nor degrees (0-360) but range of “0-2”. I’m guessing its a “magnitude of PI”.. ?

Also Is there any official documentation (on the scratch pad nodes) that could help decipher this kind of quirks ?

Thanks for your help.

Just wanted to bump this question as I am struggling to get any help regarding those topics. Thanks!

Any insights would be greatly appreciated.

With lack of proper documentation and lack of support its tough to go through on your own.
