Mod ruins 'block breaking' texture - but I don't do anything with textures?!

[Jay Avery]

I'm making a small mod which enables the user to tweak various settings about sounds, particles, and subtitles. But the mod inexplicably results in the 'block breaking' texture disappearing, somehow? When breaking a block, it's overlayed with the purple/black squares texture instead of the usual block breaking texture. It's such a strange problem, I have no idea where to even begin. Could it somehow be affected by one of the sound- or particle-related events I'm using?

 

Here is the mod on github: https://github.com/JayAvery/accesstweaks/tree/develop

Well, you do replace the RenderGlobal with a new class.  $10 says that the default render global does something special with block breaking particles.

Uhh yeah, you're right. Thanks
