X ray shader

Question

I am looking to replicate an x ray shader like this. When the player clips with an object the xray effect will only display near the clipping plane, but the rest of the object remains standard PBR. I am assuming this is some sort of advanced cut out shader. Since I am new to shader programing could someone help point me in the right direction, or to an example shader of something similar?

you don't even need a custom shader for this, just change material properties. like give it some tint and increase its transparency from script whenever you need. note that you also need your shader marked as "fade" not "opaque"

Thanks for the input :)

If you look closely at the video example though there is more going on than just changing material opacity... that would be easy enough. There appears to be:

(a) A Volumetric area to define the Partial material change on Part of a mesh (Not the entire mesh via its material settings, only the part of the mesh in the "volume" is affected. ) (b) A Gradual fade off at the edges defining a visible shape/volume to the intersection "sphere". (c) An Edge thickness defined at all points of intersection between object and "clipping volume" along surface of mesh relaying their relationship between each other.

So, to me it seems much more than just triggering an opacity change on a material.

Found something that in theory looks like it may hold seeds to an approach but seems to break down regarding its tie to camera view triggering effect even when no intersection occurs (basing things on overlap between camera, trigger and surface, not just intersections). It does work with a volume though, which I like.

It's not "the" solution but first I found that alters Partial surface, while keeping original material intact.

Thanks again.
