Hi, I like to set the particle opacity by camera distance in blueprint. I set up this blueprint so far, but it won’t work. There must be an error in the vector math of the cam distance formula, since when i make a literal float, i can see, the parameter connection works. 0 brings 0 opacity and 1 …

Use a subtraction instead of a division. Let’s say you have the camera and the actor at [1,1,1] and [3,3,3]. If you now subtract your camera from your actor you’re left with [-2,-2,-2] which is a defined length and will provide you with the result you want. However vector division is mathematical…
