Thank you for the tip; I'll edit my code so as to not mislead other folks.

If anyone was curious; I ended up actually finding source code for ExtraUtilities and found that the original developer was manually setting the opacity of the block to 255. That was done in 1.12.2, so the translation is a little different for 1.16.2. Anyways, I'd be mad if I came across this post as solved without an answer, so here's a detailed answer/explanation: To make a block see-through, but not let light through, you must override the getOpacity method and make it return 255. This makes the block "opaque," while still allowing the player to see through. To solve

That guide is fantastic; thanks for the link! I actually found your project a little earlier this morning; great stuff!

I'm a developer by trade but just recently picked up Java/Minecraft Modding, so I'm still relatively new to this. I'm trying to replicate the Dark Glass block from the Extra Utilities mod. I have the block rendering in the game, however, when placed, all adjacent blocks are missing their textures and show a gap in the world. This can be fixed by adding .notSolid() to the properties of the block, but at that point, the block lets light through. My desired effect is to have a translucent block (think stained glass but darker) that you can see through, but that doesn't let ligh
