ladders have a 3d model but not vines.
also, maybe consider adding improved models for doors and trapdoors, that don't have invisible gaps on the edges of windows.

Ladders are much less complicated to model compared to vines because they require only a few polygons compared to a ton of smaller cubes for a 3d vine. I've intentionally stayed away from doing any plants/foliage for this reason. Lilypads have been the exception because they have a hitbox and are relatively simple to model.

As far as the gaps for doors/trapdoors: this resource pack uses the exact block models in vanilla. Because they have the gaps, my models do as well. If I added them, they would break compatibility if someone wanted to use a different set of textures on their doors/trapdoors. I might consider doing these in my Inconsistency pack in the future but I'll be prioritizing finishing other blocks first.
