Steps to Reproduce

Just create a portal and enabled BSL shaders (the recommendaded in the wiki) using oculus. I tried to reproduce it using only immersive portals and oculus whithout the modpack, but the doesn't even open, also don't open with optfine. I already activated the compatilibility mode, and tried all the other settings, only setting the max layer to 0 (deactivating the portal render) sees to work.

What You Expected

I expected the portal to render only when it is my sight, also whithout the shaders the mod works just fine

What Happened Instead

I can still see the portal even when there is a full stone wall in front of me

Additional Details

The solution for similar errors i could found in this forum was to deactivate stencil buffers from Immersive Engineering, already did this too, but stiil cliping

I suspect this is identical to the following issue report: Low-Drag-MC/LDLib-MultiLoader#66

@tayrikk can you confirm whether Gregtech Community Edition: Modern was in your modpack? If so, it's specifically the LDLib dependency inside which is the source of the problem.

LDLib is in fact the cause of the problem, removing it make the portal render normal again
