Updates: I've discovered that it happens only when you have a torch equiped. (I use DynamicLights).
There's any chance to the mod to be fixed?

It also happens without a torch, but less translucent.

Shaders, the shaders causes the problem... Only to the items of these mod

Report this to the author of the shaders also. Maybe there anyone knows a fix.
