-
-## Installation
-
-Place the "Editor" folder anywhere in your project Assets folder. 
-
-## Usage
-
-### MeshPostProcessor
-
-Used to perform various operations to models on import to unity
-
-#### Add Colliders
-
-To convert objects to colliders on import, add the following strings to the object's name:
-
-* `_COLLIDER`: Converts to a mesh collider
-
-* `_SPHERECOLLIDER`: Converts to a sphere collider
-
-* `_CAPSULECOLLIDER`: Converts to a capsule collider, with the axis along the object's longest axis
-
-* `_BOXCOLLIDER`: Converts to a box collider. The box will be aligned to the object's local coordinates
-
-#### Merge Meshes
-
-Add `_MERGE` to an object's name, and all its child objects meshes will be automatically merged into one. Does not work for skinned meshes
-
-#### Delete Objects
-
-Add `_DEL` to an object's name to delete it on import
-
-#### Trim animations
-
-Automatically removes any animations with only 2 keyframes to make them easier to edit manually
-
-
-### TexturePostProcessor
-
-Used to perform various operations on textures on import to Unity. Configured with constants in the top of the file.
-
-Only works on files with the extension `EXTENSION` (default ".png").
-
-#### Specular maps
-
-If `SPEC_ENABLE` is enabled (default true), textures with the suffix `SPEC_TAG` (default "-spec") will be copied into the alpha channel of the texture without that suffix. For example, the file `foo-spec.png` will be copied into the alpha channel of the imported texture `foo.png`.
-
-#### Normal maps
-
-If `NORMAL_ENABLE` is enabled (default true), textures with the suffix `NORMAL_TAG` (default "-spec") will be marked as normal maps on import and when KSP PartTools exports the texture. if `NORMAL_GENERATE` is enabled (default true), then the texture will automatically be converted from a hightmap using Unity's normal map generation tool.

+####Additional Notes (when used in conjunction with Taniwha’s Blender Mu Plugin)
+
+For those who use Taniwha’s Blender importer, to import existing .mu’s, the following steps & notes
+	need to be addressed before importing your model into Unity with the MeshPostProcessor installed:
+
+	1) You need to make sure you only suffix the name of the *object*, and *not* of the mesh, with the above operators.
+	2) In Blender, you need to convert any imported collider instances to “real”.
+	     a) To do this, in Object Mode, select the collider instance object, then select:
+			Object→Apply→Make Instances Real  (Shift-Ctrl-A)
+	     b) Then move the new object back into it’s original place in your hierarchy.
+	        Holding Shift+Alt while dragging/dropping will keep its transforms/properties.
+	     c) Rename the *object* name, adding the appropriate operator suffix.
+			(I suggest removing the “collider:” prefix from the *mesh* name, but thats just personal preference)
+	3) Now you have to go into Edit Mode, and fill in all the faces in the mesh. Check that all of
+	   the created face normals are facing outside.
+       (When you make real the collider instances, only vertices & edges seem to get created, and not faces.)
+	   This will be apparent, if upon Unity import, you get this error, or similar in the Console window:
+		‘Can't calculate tangents, because mesh '<your_object_name>_BOXCOLLIDER|mesh:<your_mesh_name>|Dupli|' doesn't contain normals.’
