So, my suggestion is kinda simple, but yet very interesting and it would be a great addition to the mod.
The main idea is to imitate what the old Camouflage mod did, allowing you to make "hollow" blocks, that can be traspased, so when you use mods that have a lot of cabling, or you want to "hide" your carpenter safe, for example, you can build a carpenter block, and apply while sneaking, some [Insert related item here] to make them "hollow" and then apply the desired texture.
Here's an spotlight of the old camouflage mod.

Greets! and happy holidays/christmas/hanuka/whatever.

Hollow blocks are easy enough... which item were you thinking would enable this feature?

I don't know!
Maybe something new for the mod? As a "camo compund" of diferent dyes, like red green and blue (so can "imitate") with some Nether quartz to give some "post nether" kind of difficulty to create it.
What do you think?
If we look for something more "simple"... well, maybe blaze powder?

I'll add it to my list, but can't guarantee when it will be completed.

So do you think is feasible?

Ok!
Just a last quick suggestion, so I don't have to open another thread, can you invert the order of removal for the glowstone / block cover? Right now, if you use the hammer, it'll remove the glowstone first, and then the cover, and that's just annoying TBH, is that possible?

I looked into adding/removing attributes in the reverse order before but hit some snags.. I can fix it though, just need time.

Great! Thanks for the info, your mod it's great!
