BufferBuilder rendering black and purple texture

GenericMinecraftModder · July 3

I'm working on a forge mod for 1.16.5 and I made a custom Dimension and I made a custom sky for my dimension but when I test the mod the sun is just a black and purple texture, I'm pretty new at modding so I don't know what to do.

Here is the code for the custom sky:

public class ClientEventBus {
	private static final ResourceLocation DIM_RENDER_INFO = new ResourceLocation("star_craft", "moon");
	private static final ResourceLocation SUN_TEXTURES = new ResourceLocation("textures/sky/earth.png");
	private static final ResourceLocation MOON_PHASES_TEXTURES = new ResourceLocation("textures/moonsky/moon_phases.png");
	private static final ResourceLocation SKY_TEXTURE = new ResourceLocation("star_craft", "textures/sky/moonsky.png");
	@SubscribeEvent(priority = EventPriority.HIGHEST)
	public static void clientSetup(FMLClientSetupEvent event) {
		// public net.minecraft.client.world.DimensionRenderInfo field_239208_a_ #
		// field_239208_a_
		// public net.minecraft.client.renderer.Minecraft.getInstance().worldRenderer
		// field_175012_t # skyVBO
		// public net.minecraft.client.renderer.Minecraft.getInstance().worldRenderer
		// field_175014_r # skyVertexFormat
		// public net.minecraft.client.renderer.Minecraft.getInstance().worldRenderer
		// field_175013_s # starVBO
		// public net.minecraft.client.renderer.Minecraft.getInstance().worldRenderer
		// field_175011_u # sky2VBO
		DimensionRenderInfo.field_239208_a_.put(DIM_RENDER_INFO,
				// cloudHeight, alternate sky color, fog type, render sky, diffuse lighting
				new DimensionRenderInfo(128, true, FogType.NORMAL, true, false) {
					@Override
					// adjustSkyColor
					public Vector3d func_230494_a_(Vector3d fogColor, float partialTicks) {
						return fogColor;

Here is how it looks like:

private static final ResourceLocation SUN_TEXTURES = new ResourceLocation("textures/sky/earth.png");

Is your sun texture really called earth.png?

A black and purple square is minecraft's way of saying "missing texture".

Try doing the following in that method:

System.out.println(Minecraft.getInstance().getResourceManager().getResource(SUN_TEXTURES));

Actually I think your problem is that you should be doing

Quote

new ResourceLocation(MOD_ID, "textures/sky/earth.png")

You are looking for minecraft/textures/sky/earth.png if you don't specify your MOD_ID.
