Objective: Adjust the pre-built assets to give our scene a different look
First, I will need to find the texture element I want to change and locate it in file explorer.
Now that I have the texture file located I can import it into a photo editing tool. I useGimp, you can download it here
To get the effect I am looking for, I will be adjusting the Hue and Saturation.
With Gimp you can’t save the file as a .PGN format, you will need to export the image. With the export feature, you can select the PGN format. I will export the file with a new file name to the original location.
By saving the new file back to the original location, it will show up when you go back to your unity project. All that is left to do is attach the new texture map to the Material.
After changing all the Texture Maps in the scene, you can see the results below.
