Hello ! I'm on Forge 31.2.30 with Optifine pre30 (minecraft 1.15.2).

When I place a vertical slab (for exemple vanilla dark wood slab) in a world with DimensionStack of the last ImmersivePortals version, the slab texture disapear for the black&pink buggy one. It's random. For exemple, if I open a door near the vertical slabs the texture have one of two chance of disapearing.

Can you see what's wrong please ? Maybe it's an Immersive Portal bug but only your mod have this issue. Unfortunately, the issue don't provide any log in the "lastestlogs" file.

Thank and have a nice day !

Hi! Thanks for the report. I believe the issue is due to how Immersive Portals overwrites the rendering and how my slabs use something known as Model Data. I believe that this is a known issue as there is a fix in the client config for immersive portals. Simply enable the model data fix (model_data_fix = true) and this issue should be resolved! Hope that works for you!

Thank very much for the info !
Unfortunately, I use these mods for a modpack on my personnal server. I can't ask all new players to change that config on their client manually...

If it is your personal modpack, could you override the config and then put out a new version. I know it seems a pain, sorry

Sorry for the late reply. Change that config in "immersive_portals-client.toml" doesn't work for me.

EDIT : The issue occurs also with the lastest version of Immersive Portals. With "model_data_fix = true" the render bug doesn't appear in the same way. I need to place a vertical slab block at the side of another block while a vertical slab is on its side already to reproduce the issue.

EDIT 2 : Also, the render is randomly fix after fiew seconds but appear again if you place another vertical slab at the side of the support/start block.

EDIT 3 : The issue disapear when you break the vertical slab side block. Very weird...

Hypothesis : The fix of immersive portals isn't instantaneous and need time to refresh the render every time you place a vertical slab block.

I'm going to leave this issue open as it technically isn't fully resolved but unfortunately I can't see a way of fixing this from my end as Immersive Portals completely changes the rendering and loading of blocks. I know from when I tested this in a client created world using a few mods it seemed fine so it could be related to latency from the server. Hopefully if there is a way to fix this I'll be able to do it but I'm not certain

Thank for your quick reply ! I tested on a singleplayer world. I'll open another issue for ImmersivePortals. Maybe they will find a solution. I don't want to bother you any longer with this unimportant question. Thank very much and have a nice day.

I have the same issue, with the same two mods. MC 1.16.1 with forge 32.0.77. ("forge-1.16.1-32.0.77-installer.jar") Latest immersive portals ("immersive-portals-0.2-mc1.16.1-forge.jar") and latest double slabs. ("DoubleSlabs-1.16-3.2.0.jar") I will see if altering the config as suggested resolves the issue. The issue only began for me after I built my first portal, crossed over, and crossed back.

Did altering the config work?

That sounds like a completely different issue than with Immersive Portals. Would you mind creating an issue going into more detail about the issue including a log file if an error occurs?
