How block model is rendered

[DavidM]

The game does not render faces (covered by other solid blocks) that the player cannot see.

If a side of a block is covered with another solid block, then that side will be culled, as the player cannot see that side.

 

I am wondering how the game determine whether a side should be rendered when the model is not a simple cube.

If the model of a block is not cube_all, but rather a complex model created by the modder, does the game still culls the sides?

It only culls them if it is told to and this is controlled by a series of factors. Stuff like if it is opaque. Generally things that aren't full cubes are not culled because of the simple way minecraft checks if culling should happen.

Is there a block on this side. Cool don't render this side then.

Thanks.

Does the model itself affect whether sides should be culled though?
If I have a model that does not take up the entire block, but make Block#isOpaque return true, does the game still tries to cull the sides?

Not really, no.

If the block isn't fully opaque, the game assumes it is transparent, and begins rendering the sides of neighboring blocks.
