[1.7.10] Custom rendered blocks

[Kander16]

Hi,

 

I'm trying to create custom rendered blocks. But I don't get this. Everyone says that you need to make a model class, but why doesn't the cauldron have got this. I only see "renderBlockCauldron" in the "RenderBlocks" class, but no "ModelBlockCauldron" or something like this.

Can someone explain this?

 

By the way, I'm also trying to create a milk barrel which should have the same rendering as a cauldron.

 

Thanks,

There are 3 ways of rendering a block: the built-in block renderer, an

ISimpleBlockRenderingHandler

or using a

TileEntitySpecialRenderer 

.

 

Most blocks use the built-in block rendering. This compiles into a display list and only changes with block updates. It renders a chunk at a time.

 

An ISimpleBlockRenderingHandler (ISBRH for short) is a way of providing custom vertices for the block, instead of the default cube vertices of the built-in renderer This allows . This also compiles into a display list and only changes with block updates. Just like the built-in renderer, it renders a chunk at a time.

 

A TileEntitySpecialRenderer (TESR for short) is a bit different. It is a way of rendering custom models, made by Techne, Tabula or other modeling software. This also allows you to render different model formats (Wavefront (.obj) for example). A TESR is rendered every frame, but this makes it more resource intensive than a ISBRH. A TESR also allows animations in your model, which is not possible with a ISBRH.

 

There are plenty of tutorials for both the ISBRH and TESR, and it's up to you to decide which you want to use. For simple models with only a few cubes, like a cauldron, an ISBRH is better. If you have more complex models, a TESR is better.

If you followed the

renderBlockCauldron

method you'd see that it handles rendering the cauldron painstakingly one face at a time, similar to, but more annoying than, an ISBRH.
