Tutorial: Insert Alpha Channel

This documentation is for update 2.0+, applied to 5.4+.

Insert an alpha mask into an existing texture.

• Full functioning texture packer with RGBA input slots

• Choose which RGBA channel to input per texture

Open the Texture Tools via the SHADERSOURCE menu.

Add an Insert Alpha Channel Job to the queue.

Select the base texture and the texture to be used as the alpha channel (click the texture input or use the button up the top to use the selected asset from the Content Browser).

The status should change to Ready.

Select the channel from the Input Texture that you want to add to the Output Texture.

In this example, Mask Channel is set to "B". This means that the Blue Channel of the ALPHA MASK Texture will be inserted as the Alpha Channel in the OUTPUT TEXTURE.

Modify other parameters as needed.

Click Run.

The tool will now run the job and output the new texture to the Output Location. It will also export to disk if the Export option is selected.

When jobs are complete, clicking the button at the end of the Status bar will browse to the output texture in the Content Browser.
