Material optimization

Hi all, since i’m new to unity & blender i’m only making low poly models without texturing (only applying materials) like this (1) where i have a material for the leaves and one for the log.

Recently i read that using multiple materials in one scene is not good for optimization therefore it’s better to have a unique texture for the entire model.

Now, since i don’t have a clue about texturing, there’s some kind of method that can join multiple materials in a unique texture?
I have no experience in this, so if you know other ways to come around this, tell me :slight_smile:
Thank you in advance.

You probably want to look into texture atlases, not really an expert myself either but but my understanding is it reduces draw calls.
