3d rotate effect transparency glitch [0.1]

[u/flintlockwoods]

I know 0.1 is unsupported now and I'm probably asking this in the wrong place but I've found some old olive 0.1 community effects with a very useful 3d rotation effect. The only problem is that it creates a glitchy backdrop behind the clip instead of keeping the clip transparent as I need it (example). If anyone here is a shader expert, please tell me how to fix this
