Hello again, back with some more questions about rendering. I have a TileEntity that can contain multiple materials at once, but does not need to update every tick, an example of which is here: 

I am currently using a standard TESR to render this, with that code being here: https://github.com/16ColorGames/SuperTechTweaks/blob/master/src/main/java/com/sixteencolorgames/supertechtweaks/render/TESRBlockOre.java

I have heard that FastTESRs can speed up performance, as well as IBakedModels, but there do not seem to be any tutorials for either online.

Can someone help explain to me how to set up either of those?

Why do you need a TESR (fast or otherwise) to render a block?

Use the JSON model system.

because I have ~100 ores and each block can contain up to 7 ores. I'm not going to make a json for the 100^7 states that would take up

I'd recommend using IBakedModels only, as you are using this for (seemingly common) worldgen.
(The official GregTech 4 port back in 1.7.10 I believe used TESR's for rendering ores, to bypass xray, and dear god, the FPS drops)

 

1. You will need to create a custom model-cache
2. You will need to register your own ICustomModelLoader
3. You have to save your TE data to an IExtendedBlockState to provide the data for the models
   1. getExtendedState
   2. createBlockState
4. You will have to create an IModel, that points to an IBakedModel
   1. Either get cached List<BakedQuad> from your cache, or create them on the fly, and cache them in your IBakedModel

 

 

Block implementing TE->IExtendedBlockState example: Compressed Block

Model Cache example: EchoModelCache

ICustomModelLoader example: EchoModelLoader

IBakedModel example: MengerBakedModel

 

You can of course not simply copy-and-paste these; they were tailored for one of my projects, but they should give you a hint on how to do things.

Where do you set the textures to use on those? I have 1 texture that I recolor using the setcolor method in GL, how would I color and layer those?

My example doesn't use own textures, instead it creates a tessellation of vanilla and/or modded blocks, using their textures.

 

I have not handled colouring IBakedModels, so I cannot provide any information on that subject, however, for having several layers:
In the IBakedModels getQuads method, you get the state; From this state, get the IExtendedBlockState, and from that, it's properties, one which should be a collection of ores that this block "contains". Be it Enums, or mere strings, as long as you know "this block contains x & y".
Now, some pseudo-code

        List<IBakedQuad> quads = new ArrayList<IBakedQuad>();
        List<String> ores = extState.getProperty(SuperTechOre.LIST);
        
        //add stone/background texture to the quads list
        
        if(ores.contains("gold")){
        	//add gold texture to the quads list
        }
        if(ores.contains("silver")){
        	//add silver texture to the quads list
        }

The easiest approach to simply "adding" the texture, would probably be having JSON models with "faulty" ores, eg one model for each type of ore, without background, and just the actual metal/chunk parts, and get the IBakedModel from that, to add it's quads this model.
This shows how to get an IBakedModel from a resourcelocation.

You only need tint(color), right? Then it is feasible only with Json model and Block#getColor(Or something similar). Look at the model code of vanilla spawn egg to figure out the tint, and wool code for specifying the color. (As far as I know you can reference world and position there)
