Posted by CarlK3D on Jul 3rd, 2013

Importing Assets & Textures is necessary for anyone who uses a 3D Modeling Program that wants to make there own games/levels
It’s quite easy but there can be troubles if you try to import the wrong thing.
1. Asset File format needs to be something UDK can read, the most common are .FBX or .OBJ
2. Textures can be most file types such as .PNG (Doesn’t retain transparency, High Quality), .TGA (High Quality, High File size)
Textures also need to be in a correct size otherwise UDK will reject it. Acceptable sizes go by the Power of 2, such as 32×32, 64×64, 128×128, 256,256, 512×512, 1024×1024 (1k), 2048×2048 (2k), 4096×4096 (4k) I would advise not going over 4k for a texture map unless it uses many assets and not just the one.

*Note : UDK doesn’t support CMYK or Greyscale Color Modes so if you create a Specular Map from your Diffuse and Flatten it to Greyscale make sure you Ctrl A (Select) Ctrl C (Copy) open a new File and Make the color Mode RGB then Ctrl V (Paste) Save out the Spec map, it will work now.
3. Get your Asset & Textures somewhere you can find them. Go to UDK/ Content Browser/ Import (Button, Bottom Left Corner)
4. Name your Package & The Name for each Import, default should be fine of you named them correctly when creating them.
5. Save your Package by Right clicking on it in the Packages Box and Save. you can add all your assets, Textures, Materials and whatever else here for your Scene/Level

*Note : Keep your scene tidy! Other people might need to access it so each asset you Import type the Group you want it in i.e Diffuse, Normal & Spec Maps would be grouped in 2D Textures.
