When i install blockbuster and metamorph, chiseled armor from "Extra Bit Manipulation" mod becomes invisible. It influences both the player, and the actor.

P.S. Tell me if you need more info.

Which version of Blockbuster and Metamorph do you use? And also, is that your actual default skin? Or are you morphed into custom model morph?

As far as I can tell, the way this mod works is requires a special render layer to be present. However, those work only with players, and I can't really do anything about it.

blockbuster-1.5.1-1.12.2, metamorph-1.1.6-1.12.2
Yes, it default skin.

Hm, in that case, I'll take a look at it.

Apparently, it was a bug with Metamorph, rather than with Blockbuster. This fix will be out once 1.1.7 update will be out.

It would be still impossible to use this feature with Blockbuster custom models or any morphs, but... You could still use player morphs or no morphed Fake Player actors.
