Deleting colors from a forced color palette in Photoshop

This is a very specific topic, but it was hard to find information about it online, so I’ll post my findings here.

If you want to force a certain color palette on your image in Photoshop you can choose

Image –> Mode –> Indexed Color.

A window will pop up where you can choose a palette. If you want to create your own palette in which you select all the colors, you can do this:

Set the palette to “custom”. A color table window will open. You can delete existing colors by ctrl-clicking on them. You can add more colors by clicking an empty color slot and picking a color for it.

Here’s a quick gif-like video of creating custom color tables (ACT-files) in Photoshop and saving them for later use:

Multiple scene views in Unity 3D

Sometimes it’s useful to see the 3d world you are creating from multiple different angles simultaneously. Many 3D programs like 3Ds Max even offer quad views that have four different angles available. In Unity you can view your scene from multiple angles in the editor by right-clicking on the scene window tab at the top and choosing “add tab” and then “scene”. You can now drag and drop this new scene window tab to a place in the interface that you prefer and change it’s view angle to your liking. One way of working could for example be to have always one top view available and next to that one free view.

Activate camera fly mode in Unity

Here’s how to easily fly around your scene by using the standard wasd-keys and your mouse (like in a game):

1. Hold down the right mouse button
2. Press one of the wasd keys to move and move your mouse to turn

Additional tip: If you think that the scroll wheel zoom is jumping in too large increments, try holding down atl+right mouse button in order to dolly the camera smoothly by moving your mouse slowly.

Importing alpha-mapped planes from Blender to Unity

This tutorial shows you how you can bring alpha mapped planes into Unity while keeping the transparency intact:

1. Import the 3d-model as an asset
2. Import the texture as an asset and toggle the “Alpha is transparency” checkbox on. Apply.
3. Drag the 3d-model to your scene
4. Drag and drop the texture on top of the 3d-model
5. Select the object and open it’s shader in the inspector. Change the rendering mode from “opaque” to “fade” or “transparent”
