Hi! It is a common issue to want the dark theme in Unity Engine but cant afford / not wanting to pay the PRO version.

For this tutorial I will explain how to setup the dark theme in Unity Engine personal edition without much effort for those who don't know how to do it.

NOTE: THIS TUTORIAL IS ONLY USEFUL FOR VERSIONS BELOW 2019.4.8f1 AND 2020.1.3f AS UNITY NOW OFFERS DARK THEME FOR FREE.


What do you need?

- Unity Engine 2019
- A hex editor, in this case HxD.

Step 1: Setup the needed stuff.

- First of all, download and install Unity and open it. If you setup the personal license, it will show the light theme. Close it.
- Download and Install HxD: https://mh-nexus.de/en/hxd/

Step 2: Modifying Unity.exe

- Copy unity.exe from the path-to-unity-folder/unity.exe to a folder with permissions like the desktop or documents.
- Open the unity.exe with your hex editor.
- Press ctrl + F and look for the hex values:

- (in 2019.1): 74 04 33 C0 EB 02 8B 07 and change the 74 for a 75 resulting in: 75 04 33 C0 EB 02 8B 07
- (in 2019.2, 2019.3 and 2019.4 (LTS)): 75 15 33 C0 EB 13 90 and change the 75 for a 74 resulting in: 74 15 33 C0 EB 13 90

- Save it.
- Copy the modified unity.exe to the original folder.


Step 3: Resetting the reg keys

- Windows + R > regedit
- Delete the folder HKEY_CURRENT_USER\Software\Unity Technologies
- close regedit window

Step 4: Dark theme

- Open Unity by Unity Hub or .exe
- Enjoy!



Can I use this in other versions?

- Yes, you can, but you need to find the needed hex values:


(2018.1, 2018.2 and 2018.3): 84 C0 75 08 33 C0 48 83 C4 30 > 84 C0 74 08 33 C0 48 83 C4 30
(2018.4): 74 04 33 C0 EB 02 8B 03 48 8B 4C > 75 04 33 C0 EB 02 8B 03 48 8B 4C

Is this Windows Only?

No, here you have some codes for MacOS:


2019.1.0: 74 03 41 8B 06 48 to 75 03 41 8B 06 48

2019.2.3+: 00 75 15 33 C0 EB 13 90 to 00 74 15 33 C0 EB 13 90

2019.2.11 (by Jagi): 74 04 8B 03 -> 75 04 8B 03

2019.3.13f1 (By Player_One) and confirmed working on 2019.4.4f1: 06 00 0F 84 D5 00 00 00 -> 06 00 0F 85 D5 00 00 00

And now we have Linux hex values:

2019.2.12 (by Rodders): 74 02 8b 03 48 83 -> 75 02 8b 03 48 83

Yeah, the light theme is horrible xD

Wow, I'm sure there is some techniques that allow find things like that, anyone knows where to get started? Is this reverse engineering?

with cheat engine editing RAM you can find the needed values

There are also cracks. Though pro version doesn't have as many bonuses as it used to.

There are also cracks.

Why cracking the whole unity pro (which creates bad metadata) instead of spending 2-3 minutes doing this if you just want the dark theme xD

I could have sworn when I used the free Unity version a while back it had a dark theme. Did they change that?

The free version never had the dark theme. It is plus and pro version exclusive
