Dynamic block textures after model baking

[Big_Bad_E]

So, lets say I have the block dynamic_block, what I want is whenever I place the block, it sets the texture to whatever your looking at, but with an overlayed texture over the north face.

 

I am looking at the secret rooms mod but I can't figure out how it does it. (https://github.com/AbrarSyed/SecretRoomsMod-forge/blob/master/src/main/java/com/wynprice/secretroomsmod/)

 

Any help with what I would have to do, any examples or methods or whatever is appreciated.

 

I can't find anyone who asked a similar question and got the correct response. Secret rooms mod is all.

I found this method:

public static IBakedModel getModel(ResourceLocation resourceLocation)
			throws RuntimeException {
		IBakedModel bakedModel;
		IModel model;
		try {
			model = ModelLoaderRegistry.getModel(resourceLocation);
		} catch (Exception e) {
			throw new RuntimeException(e);
		}
		bakedModel = model.bake(TRSRTransformation.identity(),
				DefaultVertexFormats.BLOCK,
				location -> Minecraft.getMinecraft().getTextureMapBlocks()
						.getAtlasSprite(location.toString()));
		return bakedModel;
	}

It seems to turn a resourceLocation to a IBakedModel, but it doesn't add an overlay like I am trying to do.

 

I am currently trying to use TextureAltasSprite.load() to load the overlay onto the texture, but how would I overlay it onto a single side?

You need to take the model from the target block and combine it with a model that has the overlay, then bake and return that.

Ok, how would I do so? I found MultiLayerModel but didn't really understand how to create an instance of it, and how to combine two ResourceLocations with it.

I have been searching around, and have not found much, but I have two ideas on how to get this to work, I just don't know how to do them.

 

My first idea is to take a model (the block) and overlay it with a lock model, but I don't know how to overlay two models (like replace pixels underneath with the ones above, not add another layer.)

 

My second is to make the lock model have the lock set as an outer layer, somehow change the regular model beneath to match the block, and set the MultiLayeredModel so it will load correctly. I've found threads on how to do multi layered models and am figuring out how to change models at runtime. I'm looking at ISmartModel and IPerspectiveAwareModel.

 

Thread i've found that might be useful:

@Draco18s Hate to tag you but you know a lot. Do you have any idea how I could change a block's model on runtime, along with the texture, but put an overlayed texture over it.

[Draco18s]

Off the top of my head, no. It has been a while since I poked at it and don't remember a whole lot.

Oh, can you help me with merging textures? What method would I can to merge two model's textures? Like a chest model and a model with a texture thats a black square in the center and when combined it overlays the black box over the chest.

[Draco18s]

You can only do that during the TextureStitchEvent which is not a dynamic solution.
