I have been playing with this mod and I see that the old camo blocks are meant to be in it but they don't seem to be in the creative menu or in JEI. Is it actually in the 1.12.2 version?

They were not ported when we did the 1.12 update due to complexities with MC rendering. The plan is to eventually update them as a SBM mod. However, due to how low priority the feature was it has fallen behind due to working on the core features.

ok thanks just could u maybe remove it from the feature list on the curse forge page?

I will when its officially removed, as we still have it in older versions.
