I was doing this in the style of your todos, but it's quite impolite. I would understand if this feature wasn't interesting to you.

I am going to make a system to convert vanilla and all other mod's portals automatically

The automatic conversion feature is already implemented. https://github.com/qouteall/ImmersivePortalsMod/wiki/Datapack-Based-Custom-Portal-Generation#convert_vanilla_nether_portaljson-convent-vanilla-nether-portals-into-see-through-portals-if-the-shapes-are-compatible

However, that does not support converting end portals. Automatic end portal conversion is not being planned.

Hi qouteall, sorry to necro this old issue but I was curious as to the reasoning behind not supporting end portal conversion? It would certainly be helpful for mods like End Remastered that add their own end portal.

@Brittank88 You can use imm_ptl:one_way, see https://qouteall.fun/immptl/wiki/Datapack-Based-Custom-Portal-Generation#other-examples

@qouteall I appreciate this but I'm not sure I can.

• The new portal is made out of multiple different blocks.
• Each block needs to be filled with a different item.

I'm not sure if the parameters present allow for me to check for that.

@Brittank88 Unfortunately the custom portal system does not allow that.

I'm just surprised there's no way to tell IP to check if there are actual portal blocks at the location where somebody was, right before they changed dimensions, and then just replace them.

Apologies, that came off a bit rude. I appreciate features take time - it was a genuine expression of surprise, not an expectation that it exists. This mod is lovely regardless.
