Hello everyone!
I'm have some particles that wrap around an object (currently a sphere) they continuously adjust their rotation to align to the object's normal, I'm trying to make a test to isolate the particles when they move so that the angel between their rotation (or normal vector) and the camera (or an object/surface in the same location as the camera) is greater than a set value, basically check when this particle moved so that it's looking away form the camera, or a fresnel effect basically.
I tried using a surface test with a falloff texture, but for some reason tyflow doesn't register falloff, even when rendering.
Any suggestions or ideas are welcome!
Thanks!
