[1.12.2] Updating rendering to 1.12

[abused_master]

Hey guys, so i'm working on updating a mod to 1.12 from 1.7, but am having some trouble with rendering. A lot of their models depend on ISBRH which is no longer a thing, which i can switch over to an BakedModel, however some of them only use the renderInventoryBlock method from ISBRH, so i was wondering what is a viable option i have for editing the block rendering in the inventory?
This is what im trying to port over
 

public class BlockCatalystRenderer implements ISimpleBlockRenderingHandler {
	
	@Override
	public void renderInventoryBlock(Block block, int metadata, int modelID, RenderBlocks renderer) {
		GL11.glPushMatrix();
		GL11.glScalef(-1F, -1F, 1F);
		GL11.glTranslated(0, -1F, 0);
		Minecraft.getMinecraft().renderEngine.bindTexture(TileCatalystRenderer.modelTexture);
		TileCatalystRenderer.model.render(metadata);
		GL11.glPopMatrix();
	}

	@Override
	public boolean renderWorldBlock(IBlockAccess world, int x, int y, int z, Block block, int modelId, RenderBlocks renderer) {
		return false;
	}

	@Override
	public boolean shouldRender3DInInventory(int modelId) {
		return true;
	}

	@Override
	public int getRenderId() {
		return RenderIds.idCatalyst;
	}
}

If you were using ISBRH before, the JSON model system will work just fine for you.

What about ISBRH models that needed some GL11 functions?

You have two options:

1) If your model does not change over time (animate) then you can use the Baked Model System (the JSON system works into this)

2) Otherwise you need to use a TESR
