Blender Low Poly Window Texturing & Unwrap

OK, in our previous tutorial, we made a low poly mesh of window. in this tutorial, we will texture & export it for usage in UDK.

So, fire up your blender and load the saved file.

1.    First select the Window Top Inset Panel ( I call it glass).
2.    In Material panel, select a new material by pressing New button & name it Glass.
3.    Give it any color by choosing it from diffuse panel.
4.    Press Ctrl+I to inverse your selection (Make sure, your mouse cursor is in 3dWindow.
5.    Now, Create one more material and name it wall. and choose a color to your liking.
6.    Press Assign button to assign the selected material to the walls of the window.
7.    now, your mesh has 2 different materials, which will come handy in UDK later on.

All Materials Added

8.    Lets unwrap our mesh, so that we can put some textures on it.
9.    Arrange your window changing your time line window to UV Image Editor.

Windows Arranged for UV Wrapping

10.    Press A to select all the vertices/faces and press U to show Unwrap menu.
11.    Immediately, your whole mesh is unwrapped below in UV image editor window.
12.    Its very ugly, lets change it a bit. Deselect All, and Just select the Glass Face & Unwrap it. Better.
13.    Press S to scale it a little bit , so that we have a room for other parts of the window too.
14.    Now Press Ctrl+I to inverse the selection and Unwrap. Your remaining parts unwrap. Scale them down, and move around a bit & select all the faces.
15.    You can easily align the vertices of your walls by select them press W > Align X or Align Y.It helps in texturing.

Full Unwrap

15.    Lets Start Texturing our Window.
16.    In UV Image Editor, Select menu UV's > Export UV layout.
17.    Choose 1024 x 1024 as size and export as png. Name the file what every you want it to be.
18.    Start your favorite image editing program and load the UV layout file in it. I'll be using Gimp.
19.    Open 2 textures , 1 for bricks, other one for a window as Layers in Gimp.

23. Load up your UV layout file. Select mapping and for coordinates choose UV.

25. Your window is ready to export.

Color Palettes in Blender

Hi There,

Recently, i saw a post on a forum , where a user was very puzzled with color usage during Texture Painting of his mesh. It seemed that people are not aware of another hidden (infact it is right there in front of our eyes) feature of blender , The Color Palette.

So, today, we'll try to get some knowledge about Color Palette and how to use them.

In this tutorial, i am using blender 2.69 (official version).

It is not necessary, but you can unwrap your box , assign a texture, before moving forward.

You are required to create a folder , where you want to save the color palette, which we will make in this tutorial.

Ok, lets get started.

Select Texture Paint Mode in 3d View. My Current setup is like this.

Select the Corner Anchor of the Color Palette Properties, and move it below the Brush Properties.

Expand Color Palette Properties.
In the last line, there is a Folder Button, which allows you to Choose the Folder to save your Palettes in.
As of writing , if you try to select t…

Modfiy Premade Blender Skeletal Mesh & Export to UDK.

Today, I'll modify a ready made skeletal mesh , rigged with Riggify for export to udk.

Basic Model & Rig were made by Lee Salvemini (Sintel & Elephants Dream) in a very detailed rigging tutorial hosted here. I'll be using Blender 2.60 with Darknet's Psk/Psa exporter version 2.3.

I strongly recommend you all to step by step work with Lee's tutorial, to grasp the rigging concepts of Blender. It helped me a lot. For impatient, please download the file.

Mesh & Armature used in tutorial are not my property and are not usable in commercial application or usage. I am using them just for educational purpose. If you like to use them in your project, please contact the original owners.

Ok, Lets get started.
Start Blender & Load "comlete_rig_finish.blend".

Go to Object Data Tab -> Display Options and uncheck Shape and check X-ray options.

Our skeleton is not fully visible. lets rectify it bef…

UV-Projection Modifier - Blenders Way to Model for Game Engines

You can use this with Projection Mapping Modifier. I have added 6 cameras for projection mapping (Layer 2). You can easily extrude and manipulate your texture size as well. No need to unwrap the model. Just apply the Modifier and you are good to go

Step 1: Add A Cube and in edit mode, just unwrap (default, without seams) and keep it selected.
Step 2: Move to front View, by Pressing 1 on NumPad.
Step 3: In modifier Panel add "UVProject" to Cube.
Step 4: In "UVProject" load Image of your liking (This will be projected on the mesh. Tileable Image is good choice. Also select cube uvmap.
Step 5: Deselct Cube and Select Default Camera.
Step 6: Press Ctrt+Alt+0 on NumPad to move your camera view in front. From here you can adjust the size of Image Projection (How big or small you want your texture to show up) .
(NOTE : Ensure your camera lens is Orthographic, otherwise, your texture is going to scale, as soon as you go near the camera).
Step 7: After you are satisf…
