Automatically generate an image whose 4 RGBA channels (Red, Green, Blue and Alpha) come from other image's RGBA channels.

Specially useful to author the RGB and Alpha channels using 2 separate images.

Easy
Images with a name ending with ".SRC.DST" are used as an input to generate a texture with the same name.
SRC channels are copied to the DST channels on the generated texture.

For example, create 2 images called Character.rgb.rgb and Character.r.a to generate a texture called Character containing the RGB channels from the first texture as its RGB channels and the R channel from the second texture as its Alpha channel.

Fast
Uses the GPU to generate the textures.

Generated images always have 8 bits per channel.
