Blender

I'm about to learn blender and was wondering, what's the most efficient way to learn?

It seems over complicated, but I'm trying to learn blender too because I seen some cool things made by it

It just takes time. Trial and error however youtube is a good place to start.

I think it depends, what're you hoping to learn from blender? IE: General 3D modeling? Low poly? Realistic renders? Because I have a few tutorials I can link you to that could help (mainly towards low poly but still)

i started by learning how to make a 3d text, then progressing into learning how to animate the 3d text, then further into how to add textures.

then i moved onto learning how to render my own drawing or a simple object.

i would take baby steps because as you learn more, you'll naturally come up with questions and use youtube to guide you along the way.
