Thank you for catching my oversight!

I'm currently investigating texture channel packing and am noticing some differences in visual results based off of weather a texture is packed in an R, G, or B channel vs. the Alpha channel. Is this an expected outcome?

I'm building a large open world game that uses a large amount of texture assets (both adhoc/unique and tiling). I've been looking at utilizing Texture Arrays as part of an optimization pass and am considering moving every texture asset into an array.

Is this a naive approach? Is there any ...
