MC 1.19.2
ModernFix 3.5.1
DirTNT 1.2-1.19

By default the 2 mods together will result in missing DirTNT textures and models:

Setting mixin.perf.faster_texture_loading=false fixes that:

Let me know if this needs to be reported to DirTNT, instead.

Thanks, I've applied that workaround on my end as well as compatibility with Stitch (the library DirTNT uses for textures) does not appear to be easy. The fix will be included in the next release or you can use the dev build.

I was having the same issue with almost all the mods i had installed everything was just missing textures. Doing the mixin thing seemed to have fixed the issue.

In my case DirTNT is the only mod, that has missing textures with ModernFix.
