It does not take long to learn essential Blender techniques.
Because all the tutorials are available on Youtube.
Massive amount of tutorials.
Here is the list of objectives to follow :
1. FIND 10 TUTORIALS ABOUT HOW TO USE BASIC TOOLS IN BLENDER AND SAVE TUTORIALS IN A PLAYLIST IN YOUR YOUTUBE . . .
2. FOLLOW THESE 10 TUTORIALS AND LEARN TO CREATE BASIC SHAPES SUCH AS A DONUT WITH SPRINKLES AND SOME WHEEL AND STYLIZED CUBE AND COFFEE MUG ETC . . .
3. FIND TUTORIALS ABOUT HOW TO BUILD A BASIC HOUSE IN BLENDER . . .
4. LEARN TO APPLY MATERIAL TO EACH OBJECT OR TO EACH INDIVIDUAL FACE ON THE CHOSEN OBJECT . . .
5. DO NOT WORRY ABOUT ADDING TEXTURES BECAUSE YOU CREATE NEW MATERIAL IN UNITY TO APPLY IT INSTEAD OF BLENDER MATERIALS AND IN UNITY ADDING TEXTURES TO THE MATERIAL IS EASIER . . .
6. HOWEVER ON EACH OBJECT LEARN TO UNWRAP THE TEXTURE MAP PROPERLY FOR THAT OBJECT . . .
7. LEARN HOW TO PREVENT TEXTURE STRETCHING BY SELECTING "CORRECT FACE ATTRIBUTES" . . .
8. LEARN HOW TO SMOOTH FACES . . .
9. BUT LEARN HOW TO SELECT AN EDGE YOU WANT TO KEEP SHARP AND APPLY SHARP FUNCTION TO THAT EDGE SO IT WOULD STAY VISIBLE AND HARD . . .
10. TRY EXPORTING AN OBJECT AS FBX AND SEE HOW THEY IMPORT IN UNITY . . .
11. MOST LIKELY IN BLENDER YOU WILL NEED TO TEST IF ALL NORMALS ARE FACING THE RIGHT DIRECTION MEANING THAT EACH FACE ON THE OBJECT IS FACING ON OUTSIDE SHOWING THE MATERIAL AND TEXTURE ON IT AND IF IT FACING IN THEN IT MAY BE INVISIBLE IN UNITY IF LOOKING FROM OUTSIDE . . .
12. UNITY MAY SAY THAT SOME FACES INTERSECT SO USE FUNCTIONS TO PREVENT THAT BY SELECTING "AUTO MERGE" . . .
13. KEEP IN MIND THAT ONLY FEW ADDONS FOR BLENDER MAY HELP RIGHT AWAY AND MANY CAN BE USELESS BUT IN TUTORIALS GURUMOOROO PEOPLE SAY WHAT ADDONS FOR BLENDER THEY USE OR ACTIVATE OR PURCHASE . . .
14. EXPORT FBX AGAIN THAT SEE HOW IT WORKS IN UNITY AND IF YOU WANT YOUR BLENDER MODEL BE THE RIGHT SIZE RIGHT AWAY THEN LEARN HOW TO READ DIMENTIONS OF THE OBJECT AND ADJUST GRID AND MEASURE AN OBJECT IF NECESSARY . . .
15. KEEP IN MIND THAT IF ANYTHING WEIRDS IS HAPPENING TRY FUNCTION "APPLY ALL TRANSFORMS" . . . AND THE MAYBE SET ORIGIN OF THE OBJECT WHERE IT SHOULD BE . . .
16. BLENDER HAS SOME LANDSCAPE GENERATOR ADDON AND IT IS BEST TO CREATE AN ISLAND FASTER . . . AND THERE IS TREE GENERATOR ADDON TO GET SOME SIMPLE TREES TO SET LEAF COUNT TO VERY FEW AND BRANCH COUNT TO LESS . . .
17. START BY CREATE A HOUSE THAT YOU LIKE AND SIMPLIFY IT AND GET IT DONE . . . AND CREATE BASIC CAR NEAR . . . AND IF YOU ABLE TO GET THIS DONE YOU CAN MANAGE TO LEARN THE REST OF BLENDER . . .
