Hello,
I’m creating a few nodes for creating random scalars/vec3s. I’ve already got two done (scalar → random scalar, scalar → semi-random vec3), but I’m having trouble on the third(vec3 → random vec3).
I thought it must be something to do with the input_vars at the end?
But I’ve tried:
[input_vars[0].x,input_vars[0].y,input_vars[0].z]
and
[input_vars[0].r,input_vars[0].g,input_vars[0].b]
and even
[input_vars[0][0],input_vars[0][1],input_vars[0][2]]
But none of them work. Instead of flashing random colors like the ones I have working, this one just output a solid white.
Below is my full code. Do you see anything wrong with it?
