Mod seems to edit vanilla rendering in such a way as to crash on startup, or something else in my modpack edits vanilla rendering in a way that this mod doesn't like.

Can you zip your modpack and upload to somewhere? so I could check what mods conflict with.

Request sent.

Approved, sorry, thought it would allow you automatically

After installing all your mods I can't reproduce the issues, did you install FOT correctly? It required a ClothConfig mod.
(And I just realized I forgot to put ClothConfig as a required dependency on curseforge. Oopsie)

That's probably the cause; let me try with it

I getting a similar issue with my modpack I believe

crash-2022-07-19_22.07.18-client.txt

Remove OptiFine, that should solve an issue.
Also no response from @WalterTheMighty I think this has been fixed.
