You can perform UV texturing on a mesh within Blender without assigning a material, and you will even see it in your 3D View in textured viewport mode.
Is Blender good for texturing?
I personally prefer to use Photoshop to paint the texture on the model. Then, I edit the texture file to remove any artifacts or errors. You could make use of Blender, though, yeah. It works fairly well.4 Jul 2013
How do you texture in Blender?
How to add a texture in Blender? Go to the shading tab, drag and drop an image texture into the lower portion of the interface. Click and drag the yellow dot on the new image texture node and drop it on the yellow dot named "Base color" in the "Principled BSDF" node. We can now see the texture on the default cube.
