[1.12] Making a TESR less laggy

Well working on my TESR I noticed that having even just one of the block lowers my FPS exponentially. Any tips on how I can make it less laggy or other methods of rendering items in-world that'll be less straining?

1. Because of this:

for(int i = 0; i < 5; i++){
	for(int j = 0; j < 5; j++){
		GlStateManager.translate(-0.9, 0, 0);
		itemRenderer.renderItem(itemStack, ItemCameraTransforms.TransformType.FIXED);

		for(int k = 0; k < 5; k++){
			GlStateManager.translate(0, 0, +0.5);
			itemRenderer.renderItem(itemStack, ItemCameraTransforms.TransformType.FIXED);
		}
		GlStateManager.translate(0, 0, -2.5);
	}
	GlStateManager.translate(4.5, -2, 0);
}

 

2. Check out FastTESR.

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

I know thats the problem. Im asking if you know of a more efficient way to implement it. And I will look into the FastTESR thank you.

 

Basically I want to render the inventory of the block in-world in the model. The apples are just temporary till I get the render working.

A FastTESR would probably boost your performance significantly, but there will still be some lag as rendering 125 ItemStacks per frame is very demanding on resources.

Unfortunately when using the FastTESR I put the same code in the render method from above in the fastTESR's 'renderTileEntityFast' and it crashes.

FastTESR works differently than TESR. You cannot just copy the code from a normal TESR to a FastTESR.

Checkout: https://mcforge.readthedocs.io/en/latest/tileentities/tesr/#fasttesr

In short: You cannot reference GlStateManager and GLXX in FastTESR.

A baked model is a collection of baked quads which is a collection of vertices. They effectively are vertex data.

 

IBakedModel model = Minecraft.getMinecraft().getRenderItem().getItemModelWithOverrides(stack, (nullable) world, (nullable) facing);
	model = ForgeHooksClient.handleCameraTransforms(model, ItemCameraTransforms.TransformType, false);

Versions below 1.14.4 are no longer supported on this forum. Use the latest version to receive support.

When asking support remember to include all relevant log files (logs are found in .minecraft/logs/), code if applicable and screenshots if possible.

Only download mods from trusted sites like CurseForge (minecraft.curseforge.com). A list of bad sites can be found here, with more information available at stopmodreposts.org
