rendering of chisel blocks like the connected ones glass chisel block and metal chisel blocks rendering seems slow and rather unoptimized implemented block can be probably just youse base minecraft rendering for non connected blocks and maby connected blocks can try to use a more nicer method of connecting and rendering as in not rendering unseen faces and fixing some of the scafold factory block it makes the terrain under it see through

can be probably just youse base minecraft rendering for non connected blocks

For the most part, we do. However what we add on top of the vanilla system allows for resource packs to change how our blocks render easily.

and maby connected blocks can try to use a more nicer method of connecting and rendering as in not rendering unseen faces

This already happens.
