As far as I know, these two mods are incompatible together, it's nothing as serious as a crash but any blocks 'chiseled' with the mod turns the block invisible immediately. After asking around in their discord server it's likely due to the way ImmPtl changes rendering. It could be a total game changer if compatibility was integrated and I'm sure the dev would be willing to work with you for it! Hell, I'd pay for compatibility purely so I can live in a tiny home. Please delete this if it's already been discussed elsewhere, I checked all active issues.

compatability would be nice, but you can also use the pehkui mod on its own, or another mod that uses pehkui

Have you tried bits and chisels?

No, that's a fabric mod. I should have specified this is for the forge 1.18.2 versions.

It has nothing to do with pehkui but the portals rendering changes themselves. I want to retain the function of being able to size change by entering the portal.

Someone said that bits and chisels is compatible but chisels and bits is incompatible so it may not be similar

The fabric version may be compatible but the forge versions are not, which is what I'm trying to use.

Bits and Chisels (Fabric only)
Chisels and Bits (Forge only as far as I know)
Immersive portals (Forge up to 1.18 and Fabric up to 1.19)
