[1.12.2] Rendered Item Displays Very Dark

Posted December 22, 20186 yr

Hello, I have a TE Special Renderer that displays the item in its inventory, however, the item seems to be rendered with a heavy shadow:

I would like the render to look like an Item that is dropped on the ground. Here is the code I'm using to display the item:

            GlStateManager.pushMatrix();
            GlStateManager.disableLighting();
            GlStateManager.pushAttrib();

            RenderHelper.disableStandardItemLighting();
            Minecraft.getMinecraft().getRenderItem().renderItem(stack, ItemCameraTransforms.TransformType.FIXED);
            RenderHelper.enableStandardItemLighting();

            GlStateManager.popAttrib();
            GlStateManager.enableLighting();
            GlStateManager.popMatrix();

Thanks.

You can set the light map coordinates with the GLStateManager. Take a look at

lightmap coordinates are between 0-240, for both skylight and blocklight. You can convert a light value (from a block) that is between 0-15 to this scale with a left bit shift by 4 (<< 4). You can get the light nap coords of a block from it’s packed lightmap coords with bitshifting right by 16 (>>16) and anding (&) with 0xFFFF to get the upper 4 bytes for skylight and just anding (&) with 0xFFFF to get the lower 4 bytes for blocklight.
