Learning some hand paint, its harder than seem)

Ok, finally im fugured some about normal maps)
Planes: pretty easy
lp,hp versions - Angles affect the mapping of normals

all false geometry within one polygon

We have 3 cubes (left to right)
1 - with fasks and smooth shade, UV - single shell
2 - hard edges, UV - split islands
3 - hard edges, UV - single shell

high poly inside low, low poly as cages

2,3 bad result - because incorrect shading with soft edges, light errors
1 cube - pretty nice

at least - all sharp edges
now 1 looks not so good
2,3 looks fine
->
conclusion:

1. if angle more than 90 - make seam
2. use cage (same as low geo and put high geo inside cage than bake)
   
   

Im used XNormals for baking

export as obj - selected only: HP,LP,CAGE
In XNormals: select HP mesh, LP mesh - for LP select cage
(ngons will cause errors - infinite load)

Ps
sharp transition cause seams on object, thats why smooth transinions better
The larger the map, the more padding/margin? o_O you need)
Thats why we slpit our UV shells.

Looks pretty correct in game engine

Normals: Cylinders
final result - not best but its good for learning

finally using matcap normals as it should be, not just for fun

1st - not enougth gemetry

here right cylinder - with 90 degree angles on low poly

differency between results comes from sharp/soft edges and soft face groups

unity tests:

conclusion:

• use cages
• make seams
• use shoothing groups
• experimetns and tests

remained interesting shapes, flyers and separation when baked

Shelf.

but how it looks)

HP actually - 200k

looks ugly - but low poly)

Your work is amazing. Just kept getting better and better as i was going through it all.

Checker and measure blender system for texture density

[jakarta]

Concept modelling:
Find out how many unique needs
Gives the idea - how long it will take

Common kitbash workflow: main benefit - assets reusability
Make texture Atlas

Make simple model, UV - apply to model and make some changes

Useful for environments props.

Combine maps NM, AO, fix seams UV etc…

[jakarta]

Normal Maps baking
Hint:
Model -> mark seams properly and where angle => 90 degree mark seam, UV -> Unwrap
Next -> make modell smooth shading -> swich to edit mode with UV window
In UV editor -> UVs -> Seams from Islands

that we get => minimize normal errors (very close to the nice result, where we combine smooth and sharp shading)

First tile texture

Then the feeling is when your textures are better prepared)
In game screen: Albedo, AO, NM
