As requested an open issue,

Cave Crystal Blocks were requested, but if you have any other translucent blocks I'm sure they would be appreciated.

Reference, ChiselsAndBits/Chisels-and-Bits#400

FMLInterModComms.sendMessage( "chiselsandbits", "ignoreblocklogic", [myBlockName] );

The name should be the registry name, the same one returned by Block.getRegistryName()
