Hi,

I noticed a weird problem with opaque blocks rendering inverted (or at least oddly) and tracked it down to having draconic evolution particle generators in my inventory. See these screenshots:

This is in FTB Infinity Evolved w/ Draconic Evolution 1.0.2-snapshot_9-MC1.7.10, so apologies if this has already been resolved.

The renderer for that darn particle generator is nothing but trouble lol. As i am not able to reproduce it in my dev world its probably also interacting with some other renderer in your pack. As its a fairly minor non game breaking bug i think i will just leave it since i dont feel like tracking down the exact conditions that are causing it. I can at least guarantee that it will be fixed in 1.9
