# OptiPainting<\/p>\n
_Optimized painting rendering_<\/p>\n
## What’s this mod do?<\/p>\n
– This mod optimizes the rendering of paintings, by not rendering the sides of the painting that are never visible.
\n– In 24w18a, Mojang added data-driven paintings, which allows for custom paintings to be added to the game, up to 16×16 in size.
\n This mod removes that limit and allows you to have paintings of any size.<\/p>\n
## How’s it optimized?<\/p>\n
If you have a look at a painting, you’ll notice that on the sides there is a 2px indented frame,
\nso it sticks out from the wall. In vanilla, these faces are rendered for every single block that the painting is made of.
\nThis is a waste of resources, as the faces are never visible. This mod fixes that by not rendering these faces.<\/p>\n
This may seem like a small optimization, but these tiny faces are equivalent to the full block face, so:<\/p>\n
– Front – 4 vertices
\n– Back – 4 vertices
\n– ~~Top – 4 vertices~~
\n– ~~Bottom – 4 vertices~~
\n– ~~Left – 4 vertices~~
\n– ~~Right – 4 vertices~~<\/p>\n
Makes a total of 24 vertices per block on vanilla. And 8 vertices per block on OptiPainting.<\/p>\n
**That’s a 66% reduction in vertices!**<\/p>\n
– If you have a 16×16 painting, that’s 256 blocks, which is 6144 vertices in vanilla, and 2048 vertices in OptiPainting.
\n– If you have a super-large 64×64 painting, that’s 4096 blocks, which is 98304 vertices in vanilla, and 32768 vertices in OptiPainting.<\/p>\n

_This example is rendered without the back face to demonstrate what the mod does.
\nYou can see the back of the painting in vanilla and with the mod. (For now!!)_<\/p>\n
Obviously, if you only have the occasional painting in your world, you won’t notice much of a difference, but it
\nis free optimization none-the-less!<\/p>\n","protected":false},"excerpt":{"rendered":"
