As stated, I’m trying to order GameObjects to render in the correct order but no matter how many times I change the Render Queue to any other number it defaults to 3000.
It’s set to rendering mode Fade but this is happening in other render modes also.
Short answer: You can’t override render queue for standard shaders as “Render Mode” depends on it.
Long answer: Lets say you would be allowed to change it - when for example if you have standard shader in “Render Mode = Transparent” and decide to change its render queue to “Geometry”, as result you would had incorrect blending order with unpleasant look.
