Just a minor visual glitch, not a priority by any means.

Closing this, since Waila is rather unreliable when it comes to model rendering to begin with. I believe many of the blocks in BoP have similar issues

I mean, I can't really know why it's happening without more info. The rain collector has a separate item texture, and I mean, the model and everything works normally.

It would help if I knew what model it was looking for instead.

I'm not sure what Waila chooses to render specifically
