Join Donovan Keith for an in-depth discussion in this video Creating a stenciled graphic with the Alpha channel, part of Creating Materials in CINEMA 4D.
Layering semi-transparent images can allow you to create a complex final result that…is greater than the sum of its parts. The same is true of materials.…In this video, you'll use the alpha channel to create a stenciled graphic that…you can layer on top of another material. To start, I'm going to show you the image…we're going to be working with. I've got it open in Photoshop here.…It's a logo for a fictitious company called KinetECO, and we've got the primary…colors of the logo on the background layer.…And if we go to the Channels tab, we'll see that we have a Red, Green, and Blue…channel as well as something called an Alpha channel.…
The Alpha channel is white wherever our texture is going to be opaque.…And it's black wherever it's going to be transparent.…If you want to save out an alpha channel for an image and you don't have one yet.…Just make a selection in Photoshop, then go to your Channels tab and click on this…icon here, which will add an Alpha channel you can work with.…I'm going to go ahead and save my image now and head back into Cinema 4D.…
