[1.12] [SOLVED] Render Internal Faces


Recommended Posts

So i'm trying to make a block that has one transparent side that allows players to walk inside of it. Thanks to some help on here i've got the colliders working and i'm not working on the textures.


The issue is the inside of the blocks are culled, so looking through the transparent side lets you see through the block. Also entering the block fills the screen with the default purple/black checkboard. i can't seem to understand how to make them render correctly. I was advised this was something i can do in my json model, but after reading the wiki 3-4 times i still have no idea how i would do that.


Could someone give me some pointers?

*sees no code or JSON*

*can’t help*

The best I can do without information is tell you that you can specify cullfaces in the JSON, and you should try using BlockBench (blockbench.net) to make your models so you can mess around with the cull faces and see the results instantly

I would have posted the model json, but since it dosn't do anything about the internal faces (because i don't know how) i didn't see much point. I have no code for it since i don't know how to do it in code either.


I'll take a look at blockbench see if i can work something out with that, Cheers.

Face culling is based on the vertex draw order.... You'd have to have the opposite facing quad in the same area as the quad itself, so you'd have the northern quad, with a ' reflected' southern quad with the internal texture in the same space. Even when you're inside the block the direction is preserved, so there's no reason you can't have a southern face on the northern end of the block. even if it's 'inside' of the block, if that makes sense.

I think its my java of the variables.

Basically what Rankshank is saying is:


Quads (block faces) are inherently one-sided. If you want two-sided quads...use two quads.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
