Hi!
I’m trying to create an effect where when a saw goes through a log a gap or hole is left where the saw has already gone through, almost like the saw “negates” the rendering of the log where they intersect. The idea is to able to see the insides of the log as if it were solid on the gap part.
I’ve tried using stencil shaders but to my understanding they are screen space, so the “mask” object (the saw) would always stay in front and no depth would be considered.
Another idea is to make an “intersection object” that is rendered only where the saw and log itersect with culling set to front (would act as the inside part of the log), but I couldn’t make it work…
Any ideas on how I could achieve this effect?
(make the red part of the image “invisible” taking depth into account)
