This mod allows you to customize the pages of the Bestiary with 5 different theme. Those are Poop, Fly, Cave, Spider and Ghost.

There's only one little problem with it. The only way to enable,disable or combine the different themes is editing the anm2 file of the mod. I know that is a bad way to do it, but it was the only available option. Also please keep in mind that while this mod is works with Repentance the placement of a couple of folders is different. You can find the Repentance instructions here.


For those who are still interested here is a little guide on how to do that:


First we have to copy the mod folder.

1. Go to the [Afterbirth+ Mod] - folder. Just follow this path:
> C:\UsersName\Documents\My Games\Binding of Isaac Afterbirth+ Mods
2. Copy the [improvedbestiary] - folder
3. Rename the new copy like you want. Just make sure you know what mod that is.
4. From there we only work with the new copy of the mod.

Now we have to open the anm2 - file and edit it.

1. Go to the Animationeditor - tool by following this path:
> C:\Program Files (x86)\Steam\steamapps\common\The Binding of Isaac Rebirth\tools\IsaacAnimationEditor
2. Open the Animation editor by doubleclicking in it. The editor looks like this[imgur.com].
3. Now click on the file tap[imgur.com].
4. Click on [Open]
5. Go again to the [Afterbirth+ Mod] - folder by following this path:
> C:\UsersName\Documents\My Games\Binding of Isaac Afterbirth+ Mods
6. Open the renamed mod.
7. Open the [resources] - folder.
8. Open the [gfx] - folder.
9. Open the [ui] - folder.
10. Open the [main menu] - folder.
11. Now open the bestiarymenu.anm2 with a doublclick. The editor looks like this now[imgur.com]
12. Now click on 'Idle' in the Animation menu[imgur.com].
13. Now you can see in the 'Timelinie menu' the names of the different themes.
14. Now click on the eye symbol to make on theme visible or transparent[imgur.com].
15. After you have choosen the theme click again on the file tap (see step 3.) and click on [Save].
16. Confirm that you would like to override the xml (this animation-) file.
17. Now close the Animation editor and reload the game.


Done!


If one step is unclear feel free to ask. I will answer asap. Should you screw up the anm2 file, then just replace the anm2 file of your copied version with the version of the original mod.
