Thank you for your response.
Indeed this looks possible, my only concern and the part which I’m skeptical is that, the Textures are being loaded from a location outside of the project content folder.
I’ve never used a similar approach before, which is why I’m trying to first make sure this is possible, at a reasonable cost of course.
Modifying the rotation and lerp between less materials, instead of using 1 per frame sounds promising, I will have a look on that and thank you for suggesting it!

Packing sounds good indeed as it could make it less expensive. It is not for a game, therefore we can make use of a bit more expensive approaches, within a reasonable limit of course.
