In short:

• Aether, Twilight Forest, Call from the Depth mods

These are the main mods I have, and I was wondering if it would be possible to use these blocks with the rechiseled mod someday.
*or maybe adding option in .config to adding id block that can be used for rechiseled mod

That would require tons of time creating alternative textures for the blocks from those mods. It is not as simple as 'allowing them to be chiseled'.

*or maybe adding option in .config to adding id block that can be used for rechiseled mod

But how would this work? I would somehow need block properties, what kind of block it is and how it gets placed (like cobblestone, pillar, directional), textures from somewhere, etc. in order to create variants for any arbitrary block that is added to the config.

I thought it was just a simple matter of adding the id block "what I want" and that's it... nothing special.
But okay, since it's so complicated to add.
I preferred to ask if there's anything It possible to can about it.
But okay.
Thanks for the reply ^^
