Please help w/ Immersive Portals compatibility (please comment a solution if you have one)

ive been at this for so long please help me

so im tryna make a non-euclidian map, that looks good, and with a ton of mods, so im using immersive portals (and forge bcuz forge is objectively better for content) however imm on forge is really terrible for the early versions which i am using.

my first thing was using 1.16.5, but i couldnt figure out how to get shaders w/ imm portals, so i eventually gave up. if someone can find a way to do this, bcuz rubidium and embeddium just result in an unrendered world, i will be happy

second, i tried to switch to 1.18.2, but that doesnt work bcuz even tho i get shaders and imm portals, chisels and bits doesnt work which is very important for the thing im doing, as when i chisel the blocks they stop rendering. I heard on fabric this was fixed with indium, but i used an indium port called reforgium and it didnt work. alternatively can someone solve this one, either one will work but ive been at this for so long, so please look for a solution

tell me an alternative if its truly impossible for any of these outcomes
