-==== Step 2 – Join Into One Object ====
-Select all objects.
-**Select one last as active** (it becomes the base object)
-→ ''Ctrl + J''
-Now you have one mesh containing all objects.
-Important:
-Check for duplicate vertices if objects were touching:
-Go to **Edit Mode** → ''A'' → ''M'' → **By Distance**
-This cleans overlapping vertices.
-==== Step 3 – UV Unwrap Properly ====
-Now that it's one object:
-Go to Edit Mode
-''A'' to select all faces
-''U'' → **Smart UV Project**
-Adapt projection method if needed for geometry.
-Adjust angle limit if needed.
-Open UV Editor and confirm:
-  * No overlapping islands
-  * Good space usage
-If you want optimal packing:
-**UV → Pack Islands**
-==== Step 4 – Create Bake Target Texture ====
-Switch to **Cycles** (baking only works in Cycles).
-In Shader Editor:
-Add **Image Texture node**
-Click ''New''
-Choose resolution (512 - 2048 or 4096)
-Name it “Object_Baked_BaseColor”
-<WRAP round important 30%>
-**IMPORTANT:**
-Leave this Image Texture node selected (highlighted).
-This tells Blender where to bake.
-</WRAP>
-==== Step 5 – Bake Maps ====
-Bake Base Color (Albedo)
-Render → Cycles
-**Bake Type:** Diffuse
-Disable:
-  * Direct
-  * Indirect
-  * Leave only Color checked
-Press ''Bake''.
-Save the image afterward in Image Editor.
-Repeat the process for Normal Map:
-  * Create new Image Texture → “Object_Baked_Normal”
-  * Select that node
-  * Bake Type → Normal
-  * Space → Tangent
-  * ''Bake''
-Repeat the process for Roughness (if needed)
-  * Bake Type → Roughness
-==== Step 6 – Create a New Game-Ready Material ====
-Now create a clean Principled BSDF:
-  * Plug BaseColor texture into Base Color
-  * Plug Normal texture → Normal Map node → Principled Normal
-  * Plug Roughness texture into Roughness
-Remove all procedural nodes.
-You now have a lightweight material that works in any engine.
-==== Step 7 – (Optional but Recommended) Apply Transforms ====
-**Object Mode**:
-''Ctrl + A'' → **Apply Rotation/Scale**. In most cases don't apply location if your object is not an independent asset placed at world origin.
-GLTF likes clean scale = 1, rotation = 0.
-Game engines prefer clean transforms.
-Also ''Shift + N'' → Recalculate Normals.
-Game engines like clean normals.
-==== Correct Modifier / Boolean Order ====
-//For example when a window is applying a difference boolean on a wall for easy placement//
-Recommended Order:
-  * Finish modeling
-  * Apply Boolean on wall (for window cutout)
-  * Clean topology
-  * Apply bevel
-  * Join bricks (if needed)
-  * UV unwrap
-  * Bake
-  * Apply transforms
-  * Export
