New PS Tutorial - Layer Panel and Keyboard Shortcuts 2

This week we finish exploring the keyboard shortcuts to use with layers with the shortcut for making a Clipping Mask, deleting a layer, and a couple of caveats about using the shortcuts.

Hope you enjoy it!

If you have anything you really want to ask about for next week, please do! I haven't decided what the tutorial is going to be about yet.

Hi Robin! Thanks for your helpfull tutorials. I've been using your templates since I started designing skins! I've recently started making clothes, and while looking for tutorials about how to make lace textures, I found your your webiste. Your tutorial about how to make lace out of prints is fantastic! Thanks for that!

I have a question, I would like use a lace texture as part of a shirt and just can't figure out how to do it because I would need two alpha channels, which is not possible. Do you know how to do that?
I'll be very grateful for any help you can give.
Warm regards,

Hi Pearl! Thanks for your kind words. I'm glad that you've found the tuts helpful. :D

You do it by combining the alpha channels.

The easiest way to do that is to open the Channel panel, select one of the channels, tap Command A to Select All (ctrl A on a PC), and Copy.

Move to the Layers Panel, make a new layer, and Paste. That will put the grayscale image from the channel onto the new layer.

Repeat for the other channel.

Then, in the Layers panel, set the one on top to Multiply. You'll be able to see your combined image. Hold down the Command key (ctrl on a PC) and tap E to merge the layers.

Then Select All again, go back to the Channel panel, and paste the new image into one of the channels.

Delete the other one. (Very important, since if you try to save an image with 2 alpha channels in tga format, you'll get a solid white alpha channel in SL. Which means that it won't look like you have any transparency at all, but you will have alpha sorting issues.)

Hide the combined alpha image in the Layers panel, and you're ready to upload.

Or, if this is the only shirt you're making this way, just save in .png format!

Hope this helps!
