Choose 2-bit for smaller memory use, but lower quality,Ī tab is created for each texture. This is a slow operation, so by default "Convert PVRs" is deselected. When the PVR file format is selected, first the texture atlas will be created as a PNG, then the PVRTexTool will be called to convert it to PVR. This is the file location where you installed the command line PVRTexTool. The alpha threshold indicates what is considered to be transparent.

Transparent pixels are trimmed off all source images. Non power-of-two means there is no restriction at all. Power of two restricts the size to power of two dimensions (ie. This is the maximum texture size (both width and height) for the device you are targetting. Advanced optionsĬlick on the "Options." button to open advanced options. The texture atlases will be saved to the same directory. Select the name and location of the output file. This is to prevent pixels appearing from adjacent images (the PVR algorithm draws pixels outside of the image borders). Note: a padding of 2 pixels is created around each image. This format works better with "organic" images with no transparent borders. gradients) will look bad.Ĭompressed PVR format. Textures with subtle colour changes (i.e. The file is 32-bit, or 24 bit if there is no alpha channel.Ĭhoosing this option uses only 16-bits per pixel, but reduces the number of colours. This means the file will look odd if you open it on your PC, but it will look fine on the device. Note: targa files have RGB bytes in OpenGL order, so they load faster. The required file format for each directory Of the input folder and the directory structure will be shown.

Organised in directories according to file format. The source images for your project must be in PNG format and must be

You may also need to install the PVRTexTool from Imagination Technologies if you want to create PVR compressed textures. You will need Java installed on your machine to use it.

How to useĭownload the file AtlasMaker_jar_2.2.1.zip and unzip. The code is c++ and designed to be portable. The tool is written in Java and runs on Windows, Mac and Linux.Ī sample iPhone project is included, that demonstrates loading the texture atlas. Who is this for?Īlthough the tool was developed for the iPhone, it is useful for most platforms including Android and PC. Images in one texture allows draw-call batching: in other words several On some platforms OpenGL textures have to be sizedĪs power of 2, loading the images separately would require a lot of Java source code provided, so you can modify the tool for your own needs. Creates multiple atlases with multiple formats, all with one click. Loads textures nearly 5 times faster than loading from PNG I've decided to open source our in-house texture atlas creation tool,īecause I think this will be useful for other independent game
