Robert Swain 84991d34f3 Array texture example (#5077) ... # Objective - Make the reusable PBR shading functionality a little more reusable - Add constructor functions for `StandardMaterial` and `PbrInput` structs to populate them with default values - Document unclear `PbrInput` members - Demonstrate how to reuse the bevy PBR shading functionality - The final important piece from #3969 as the initial shot at making the PBR shader code reusable in custom materials ## Solution - Add back and rework the 'old' `array_texture` example from pre-0.6. - Create a custom shader material - Use a single array texture binding and sampler for the material bind group - Use a shader that calls `pbr()` from the `bevy_pbr::pbr_functions` import - Spawn a row of cubes using the custom material - In the shader, select the array texture layer to sample by using the world position x coordinate modulo the number of array texture layers <img width="1392" alt="Screenshot 2022-06-23 at 12 28 05" src="https://user-images.githubusercontent.com/302146/175278593-2296f519-f577-4ece-81c0-d842283784a1.png"> Co-authored-by: Carter Anderson <mcanders1@gmail.com>		2022-06-28 00:58:50 +00:00
