[main jetty]

Minecraft hides (culls) the faces between solid blocks to improve performance. To avoid this, remodel a non-solid block. For example: Glass, Pressure Plates, Flowers.
Alternatively, display the model by putting it into the head slot of an invisible Armor Stand or inside an invisible Item Frame.

(and for the other thing do Ctrl+A, then Tools > Remove Untextured Faces (or something like that))

Ok thanks you

[terse orbit]

I do it but...

[terse orbit]

Is remove blanks face?

[strange abyss]

yes, that one

[strange abyss]

do what?

[terse orbit]

remodel a non solid block(rail)

[strange abyss]

well, the rail isn't causing culling

the crafting bench is

which is not a non-solid block

[terse orbit]

I did it whit a flowers but i didn't work(i know is not beautiful but is a teast)

[strange abyss]

the problem is that the crafting table is a solid block and hence culls the block below it, not that there is a flower or similar next to your crafting table

[terse orbit]

how do i make the crafting table a non-solid block?

[strange abyss]
