The prism changes the way it splits the red green and blue lasers based on direction. http://i.imgur.com/X1NV6C9.png

That's how physics works.

Um, what, yes that is not how physics works so that is why it needs to be fixed? All the prisms are facing the same way with the laser hitting the flat back of the prism. But the laser splits differently depending on which compass direction the laser is going. So eatch laser is in the same scenario but acts differently.

oh I get what you mean.
Definitely a bug

I can confirm this bug. I captured this in a test world: https://i.gyazo.com/28bf034b28978a34ac385bee516eb64d.jpg

@TheDeviantCrafter Yes, the issue is from escapee's math somewhere. We'll see what we can do but math is hard.

Unfortunately, math is too hard, so we wont be dealing with this any time soon. Sorry :/

Issue will stay open.

Closing this issue for clean up.
things have changed with the port to 1.12.2 and i wont support lower versions.
If the problem still occures do not hasitate to create a new issue!
