Crash Report (if applicable)

No response

Steps to Reproduce

1, load oculus shaders and immersive portals.
2, make two portals within the same render distance, effects better if pointsing towards eachother
3, turn on any shader pack
4, view

What You Expected

I assume the shaders to ignore the portals or interact normally with the portals as if they are surface.

What Happened Instead

The shaders i assune kept looping into eachother creating odd visual errors

https://gist.github.com/TofuHell/fc9ddc97de958f26756bb55b144230c8

this was with Forge 40.1.0 and Immersive Portals 1.4.12-mc1.18.2

Did you test it with a different shader?

yes all big shaders (complimentary, seus, sildurs, BSL, etc) experience this problem unfortunately

I can't reproduce this. But SEUS / Sildurs are quite known for causing issues with mods in general. Complementary / BSL should work, I test on both of these shaders. But as I said, I'm unable to reproduce this. Can you please tell me your

• Java Version and Vendor
• OS and Arch

And try again with the latest versions of all mods involved.

im sorry for being so late. The issue was something with my graphics card drivers, i had recently upgraded. I'm sorry for wasting your time.

No problem, glad you resolved it.
