Add favorite folders in Ubuntu

A standard Ubuntu installation with Gnome as the desktop has a starred locations option in the sidebar. That sounds like an obvious way of adding often used folders to favorites so that you can access them quickly and easily.

Unfortunately it turns out that the “starred” feature doesn’t always work as easily as you would hope. You might think you could simply right click on a folder and choose to star it from the context menu. But there is no such menu option. Some people have gotten adding stars to work by going to the list view, and right clicking on the column header to then add “Star” as a column. But even when I could add that column and see the star, I still couldn’t turn the star on for the folder that I wanted. It seems like this feature might work mainly for indexed locations.

Luckily there is another way of adding favorites or bookmarks to Gnome. Simply start dragging a folder towards the sidebar on the left. Now pay attention to a little button that appears which says “new bookmark”. If you drag the folder on top of that, it will now appear in the sidebar as a handy bookmark.

Create new files by right-clicking on Ubuntu

I just learned a really helpful tip regarding Linux Ubuntu. I have been missing the possibility to quickly create new files by right-clicking on a folder. With this simple technique you can create all kinds of files quickly and easily. The steps are really simple:

  1. Open the program that can create the files that you need. For plain text files for example you can open Gedit (or “Text editor”).
  2. Save a file with the desired format and desired default name into the Home/Templates folder.
  3. Now you can simply right click anywhere on a folder and you have the ability to create those files.

Finally a sprite sheet recoloring process that works

I have been searching for a good workflow for testing out different color palettes for existing video game designs.

I have finally found a relatively pain free method of testing different color palettes and applying them to entire games. I will be making a video tutorial about this in the future, but before I get to that, I thought I would already explain the basics of the workflow.

Basics of Using Cryptomatte in Blender 2.93

In the buttons area (on the right side of the interface), select the “View layer properties” tab.

Under “cryptomatte” turn on “object”, “material” or “asset”. I like “asset” since it let’s me select entire rigs that consist of several parts.

Go to the “compositing” workspace.

Turn on “use nodes”.

Add a viewer node with shift+a –> output –> viewer.

Add the cryptomatte node from Matte –> Cryptomatte.

Connect the image output from the render layers node to the image input of the Cryptomatte node. Connect the “pick” output from the Cryptomatte node to the image input of the viewer node. Render the scene (keyboard shortcut F12).

You should now see different matte colors that identify different assets in your render layer. Use the + button to access the eyedropper tool and select as many assets as you need for the matte you are building.

To see the actual matte, you can plug the “matte” output from the Cryptomatte node to the viewer.

Now you have a matte that you can use in various way when you are compositing. As a simple example, you could color correct the matted area by combining two copies of the input image with the “AlphaOver” node while using the matte as the factor. Then simply drop a color correction node like RGB curves between the bottom image connection.
