So I've managed to backport Voxy to 1.21.1 and have built the FixSodiumShader jar to be able to play on Neoforge 1.21.1, but I'm facing an issue where as I'm moving or rotating the camera, empty blocks are appearing/disappearing. I'm not good with modding but I've been trying to figure this out for a while and have had no luck. Would really appreciate any support. Below are the links I used for the build
