Shared texture samplers as parameters (material instances)

shared texture samplers are a great thing. If I understand it correctly the textures are cooked into one large texture? Does this also work with material instances and texture sample parameters?

So can I create a material with 5 texture sampler parameters, then create an instance of this material and fill in my 5 “true” textures and they are combined into one large texture?

Or am I completely wrong about shared: wrap?

You are indeed wrong.

samplers are just a set of rules, that define how texture data is retrieved.
