Basically, I’m using a set of premade puzzle pieces as Opacity Masks to overlay onto the “puzzle-to-be” image, then capturing them as Render Targets each time, thus giving me the image as separate puzzle pieces. I’m now looking for a way to crop out the empty parts of the texture so that the resulting render target is only as large as the opaque part of the puzzle piece.

So basically, this:

Anyone know how I could go about doing this please?

Hey there @Zarrar2802! I’m not well versed in material operations, but cropping would have to happen on the material level like this thread.

How to both crop and pan a texture in material

I have padded / atlas textures I would like to use in a billboard material I am making. I am trying to figure out a way to both isolate the correct part of the texture, and be able to do operations like panning and tiling on it without getting the rest of the texture in the image. Right now, I can get the cropping looking correct, but then when I offset it or pan it, I see the rest of the cropped part of the image. I tried passing my UVs through to a custom UV channel but that didn’t seem to he…

Thank you! I’ll have a look through that post.

Absolutely! I know it’s a bit different than your use case but I believe the cropping (and not much of the panning) should help. If it does help out, let me know! I can use the post (or this one) as a reference for others in the future!
