 ===== Baking Textures =====
-==== Step 1 – Apply All Modifiers ====
+For baking textures visit : **[[export-runtime|Exporting for Real-Time Engines]]**.
-Select all objects. **F3 → “Convert to Mesh”**
-OR
-Object Mode → Object → Convert → Mesh
-This applies all modifiers (including bevel) destructively.
-If you prefer manual control:
-Select one → Modifier tab → Apply
-Repeat for all (less efficient).
-==== 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 stones 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
-For stone walls, Smart UV works well.
-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 (2048 or 4096 for walls)
-Name it “Stone_Baked_BaseColor”
-IMPORTANT:
-Leave this Image Texture node selected (highlighted).
-This tells Blender where to bake.
-==== 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.
-Bake Normal Map
-Create new Image Texture → “Stone_Baked_Normal”
-Select that node
-Bake Type → Normal
-Space → Tangent
-Bake
-Save image.
-Bake Roughness (if needed)
-Bake Type → Roughness
-Repeat process with new image.
-==== 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 All Transforms
-Game engines prefer clean transforms.
