there are a few threads about decals and I’m going through some other code ive found.
But i was wondering if anyone here had any code for grabbing the mesh geometry within a cube with an eye to making decals.
I’m aiming to copy the geometry and crop it to the bounds of the cube. Any links or code much appreciated , im frying my brain at the moment 
Thanks
I ended up tearing some code out of the Bootcamp demo as they use a Decal system in there. Used it as a guidline and made a simpler version.
The decals go down fine, and sometimes the texture UV’s work , but alot of the time I just get a streak across the texture, I noticed in Bootcamp when the bullet holes wrap round a corner they streak as well.
Anyone know how to get a nicer result from decal UV`s?
Well I dropped my implementation into my game without the UV fix and it runs like a dog. Totally useless for what im doing (im basically trying to create a system for shadows that’s faster than the Unity projector.
The current system takes the whole mesh (a big landscape) and crops it down to a small decal, very inefficient.
I was wondering if there is a fast way of grabbing only a selection of geometry close to a point.
