Fix Railgun Projectile Rendering
If the projectiles look like they are flying in the wrong direction (with or without this mod) (this is a general minecraft issue, not immersive engineering), use this mod to fix the issue:

IE Tool Tweaks Wiki
======================================================
I am open for suggestions on how to improve the default content for this mod :)
Changes to the data structure for mod pack authors (e.g. adding customizable saw blades) are not planned at the moment but might be tackled once this mod has been out for a while and I have collected some feedback. I will do my best to not change the existing datapack structure when I add new attributes / modifiable items.
