Hello, I am using the mosaic tool to layer several 4-band images. Band 4 comes in to Photoshop, as expected, as an alpha channel. When I run the tool, the R, G, and B channels are correct for each layer, but the alpha channel shows only the top image pixels for each layer. During the mosaicking process, I can see the correct pixels being added in the channel palette, but when the process finishes, only the top image pixels remain in the alpha channel for each layer. This happens with or without "mosaic alpha layers" check box checked or unchecked. How do I get the correct data in my alpha channel, per layer, after mosaicking?
