The portals are rendered as if the shaders are not there

It only looks correct when you get close

Hi, I assume support for this is still unlikely to be added? I am working on a project involving custom vertex shaders to distort the world and immersive portals, but none of the available optifine gbuffers vertex shaders have any effect on the portal edges.

I don't think it'd be that hard to implement as the portals could warp just on each grid point as these blocks do:


You wouldn't have to add any points, just move them. (If we're dealing with a large portal, you could add a few points to prevent it from being a straight line instead of curved as the shaders intended)

Supporting psychedelic shaders is very hard and not worth the effort.

Immersive Portals' renderers were not designed to be used with shaders that actually distort space. I believe it simply uses the portals' shape rather than going through vertex shaders and what have you. I believe this is WAI

Also, is shadersmods.com like CurseForge or does it need some https://stopmodreposts.org/ ?

I don't really know, I just used it as an example, but here's an image

I actually checked it out and it seems like they're just storing direct links to shader mods.
