    Tips, news, and insight on KeyShot and 3D Rendering

    A common part of creating drop dead gorgeous 3d images, is rendering them in KeyShot, then taking them into Photoshop for some post process work - adding some flames, mixing in some filters or simply adjusting the exposure. One feature you have with KeyShot makes this even easier. You can save out a rendering with a completely transparent background. It's extremely simple to do and allows you to drop the 3D rendering onto anything you like, and as you'll see in the following tutorials, apply all sorts of special effects to your image.

    KeyShot Alpha Channels

    As mentioned earlier, it's extremely simple to save out a rendering with a transparent background with KeyShot. This is called Alpha channel transparency. An alpha channel is an additional channel, which contains information about transparency, that is added to the image. This is common for .gif, .png and .tiff file formats. In KeyShot we have a single-click option to apply alpha. In the Render options when the render output is TIFF or EXR you'll have the option to Include Alpha by selecting the checkbox to the right. That's it! After you hit Render, your saved image will have a transparent background, ready to be brought into Photoshop or image editor of your choice.

     

    These two tutorials show you the steps to take after you bring your rendering into Photoshop. From there, you have all the options Photoshop provides to create the mix of effects you need. How do you use KeyShot and Photoshop together?
