Ignore Line Trace for Masked parts of objects?

[Nonlin]

@MostHost_LA

if you break your hit result you should be able to get access to the material to perform whatever check.

however, if you trace on the visibility channel, is the masked object that is invisible actually considered visible?
that sort of defeats the purpose of the visibility channel, doesn’t it?

well how to get invisible pixels out of the material with no texture to ref? Before I’d look at the texture and get the color at pixel coordinate (x,y), don’t have a texture ref this time.

And yeah that is just a channel name doesn’t seem to be pixel perfect visible/invisible.

But that doesn’t seem to work. Despite some parts having alpha of 0, still shows up as full.
