TGA is generally used to make sequence diagrams, that is, animations. It has a transparent channel and can also make game icons.

Three-dimensional software (MAYA 3D, etc. ) and PS can do it. For example, make a short animation and then render it into TGA format, use AE import for decoration, or make an animation directly.

Half of the images in TGA format can be post-synthesized, which is also the most important output file format of 3 D special effects files.

You can use PS as the TGA format of the game.

The method is also very simple. Create a new layer on the Channel Mixer panel, and then paint the icon that you want to display as white. What is not shown is black. The brightness of the display is represented by gray scale. In other words, the clearer you want to show it, the whiter it will be. There is a trick, you copy any channel on it directly and then copy it to the new channel. However, the effect caused by this method is not the best, and it is best to download it manually.
