Is it possible (or do i have to) to change Texture properties dynamically (outside of Texture editor)?

Or i should always setup Texture properties once (like statically)?

Check out how Material Instance Dynamics work, I think that will answer your question.

This is a good place to start:

Texture or material?

Strictly, Texture. Because i know that Material can be changed dinamically and can be instanced also.

I am trying to achieve perfect understanding of capabilities and mechanics of UE4. I was almost sure that textures are not supposed to be changed dynamically outside of materials, i just wanted to be clear with that. Thx for answer.

Anything you could change in your texture properties you should be able to change via a Material Instance Dynamic. The only ‘Dynamic’ texture I know of is a render target. Can you tell us what you’re trying to achieve by changing texture properties dynamically?
