Void Block
Simply adds a block that renders the void portal effect. Works for Fabric 1.21.1 and works with or without shaders! I will almost certainly never, ever be updating or changing this mod, because I'm genuinely surprised it works at all as it is, and I'm terrified that if I change ANYTHING inside it it'll break.
Required on both server and client. No dependencies.
Features
Void Block - renders the End Gateway effect
Shader compatibility - NOTE: I recommend Solas Shader as it's one of the few I've come across that renders the End Portal effect screen-space aligned. Others don't, and so you can see the 'seams' where perpendicular surfaces built of void blocks meet. MASSIVE thanks to fayer3 for adding the shader support :)
Redstone controllable Redstone control can be toggled on or off in the configs by setting
"enableRedstoneControl": <true|false>

Shader support was very kindly added by fayer3 - MASSIVE thanks to them
