The documentation on the Sine node ( Math Material Expressions in Unreal Engine | Unreal Engine 5.2 Documentation ) sais that the input is in radians, but it seems the input is pre-multiplied by PI, so that a input of 1 is actually PI radians. Please fix documentation, or fix the Sine node to act as t…

Thanks for pointing that out, BramV. It appears that the entire run of the Sine or Cosine function is mapped to the range [0, 1], so 1.0 would indicate 2 PI radians, or 360 degrees. The reasoning behind this is that “zero to one” mappings are very convenient since they can be used easily with things…

Documentation is wrong on Sine node
