Help Needed For Baking, Textures, Meshes for Export to Unity Game Project

Blender V2.75

Hello guys, I’m new to blender been doing a lot of tutorial work from youtube videos I found.
My friend is making a hobby game in Unity game engine and asked me to help with 3d models/animations.
I have zero experience except for this week of work and have made cups and clocks and hats etc (easy stuff).
I understand the modeling parts pretty ok, texturing somewhat ok, but baking not so ok.

Most tutorial vids and or help links are for rendering which include lights and shadows.

Issues:

  1. My friend wants NO SHADOWS OR LIGHTING (or just a single light) in my end products, but I don’t know how to bake without the lights and get a clear texture bake.
    I found some sites, but the options in properties and in materials they had I don’t have in my blender v2.75 and so I’m lost.

  2. He griped or I should say unity engine griped at my end products because they are in too many parts. Even after I use CTRL+J to add them together. Unity says: too many mesh parts, it wants them all into 1. So I’m very lost on this.

  3. When working with planes to make a knife, I have issues finding the wire frame on planes, do I need to select triangle vertices?

Asking for help!

If one of you could make an updated tutorial for the problems I’m having and or are willing to tutor me for a bit, I’d be more than willing to maybe gift you a steam game or donate some money. I don’t have a lot of money but I know most things aren’t free in life.

Please help you smart guys!
