How To Make An Object Fade As Another Intersects With It? I have a basic cloud texture on a plane, this is my node set-up: https://i.imgur.com/dqLENEa.png.
My question is; How do I conserve this node set up while also adding a geometry intersect fade node set up? I want the cloud to fade to total transparency the closer an object gets to it's proximity. I would also like the object to fade away the closer the camera gets to the plane. And also, this may be a very simple one, but how would I achieve a transparent circular mask over the cloud so that the edges are transparent in a circular shape? Thanks guys!
Finding a falloff that drives the transparency depending on the camera proximity.

The node setup:


Take the coordinates of the camera as &quot;object&quot; in &quot;texture coordinates&quot; node.
Get its length to the mesh &quot;vector math&quot; using &quot;length&quot;
Add a little value so that we won't reach 0 in next node
Negative power so that the value is bigger as the length decreases
Tweak the curve using &quot;vector curve&quot; on X: small values are 1 and bigger values have a falloff to 0 rapidly
Get the X component tweaked above
Multiply the result with the value that already drives the cloud transparency, so that transparency is due to both the texture and the result of the proximity

You may have to tune values and curve depending on your cloud/plane configuration and size.
