I recently got into texture pack making, and created one that turns the entire UI (that is, inventory, buttons, menus and such) red! This is free for anyone to use, download it below. I'll include a guide for implementing it as well :3
Main Menu Options:
Realm Banner and Inventory
Besides those screenshots, there's lots more!
First: Accessing the Textures
How to use your new texture pack! (Windows instructions, I don't use Apple so I don't know how that works. You'll have to figure it out yourself if you're using a Mac, sorry!)
1. Open Libraries
2. Navigate to This PC > Local Disk > Program Files (x86) > Steam > steamapps > common > Cubic Castles > Dyna Content > images
You should now be in the "images" folder, which means you have your textures open. Download my textures if you haven't already.
IMPORTANT: Before you do any of these next steps, select ALL of your textures, copy them, and paste them in a new folder. This folder can be put anywhere, on your desktop or in images, just keep it safe. These are your backup textures. If you ever want to change your game back, you absolutely have to have these.
Next: Installing the Textures
3. Open a new File Explorer
4. Navigate to your Downloads folder, and select all of my textures by holding ctrl and clicking on each one
5. Drag these 3 images to your other File Explorer, the one that's open in the "images" folder
6. It will prompt you, saying "This destination has 3 files with the same name." Click replace, and my textures will replace the old ones
Now you're all set! Don't forget your backups, store them somewhere safe. If you ever want to change the textures back to normal, repeat these steps by dragging the old textures into the folder and replacing mine. Enjoy! :D
If you forgot to save your backups and want to change it back to the normal textures, contact me through profile messaging! I'll link you the old textures :3
When you download these, click on the image link below. It will take you to a new tab with the image. Right-click on it, and select the "save as..." option. When you save it, MAKE SURE you name it the exact same thing I named it! E.g., when you save the Control Panel textures, you HAVE to name it ControlPanel. Otherwise, it won't work. If you have any questions, again, profile message me! :D
Happy texturing! - Jack
