Mod Descriptions

Select a JCE spell from the spell menu and use it as your shout key (Z by default). If the action is available, end the current action immediately and cast it.
For casting, you must have 80% or more of Magicka, and all Magicka will be consumed when activated.
Damage dealt is the sum of all attributes. The amount of damage inflicted depends on the game difficulty setting.

Known Issues

• IMOD Monochrome effect not being applied. / Requires ENB that supports Image Space effect.
• The NFAC sticky version will ignore magic effects under certain conditions, which causes JCE not to hit.
• True Directional Movement - Head Tracking / If you use Nemesis' head tracking, There is a bug where the upper body leans to look back while JCE motion is playing. 
• Bug causing characters to become invisible on certain interior walls / I know how the problem happened, but I don't know how to fix it.
  

• Console commands don't work / The cause of the problem is unknown.
  

Q&A

Some of the effects do not play.
 - If the FX slot (61) is being used, some effects may not play.

There is a bug where the weather switches instantly when casting in the process of changing the weather.
 - Due to papyrus script support limitations, the outgoing weather will change immediately.

I used a shout, but the JCE animation is not playing.
 - Make sure your DAR is working properly.

I used a shout, but a completely different animation is playing.
 - Modify the priority of the DAR folder.
If you don't know the folder priority of your DAR, use the following simple method.
Judgement Cut End - ap05's Remake\Meshes\actors\character\animations\dynamicanimationreplacer\_CustomConditions.
Modify the folder name 2150004905.
This value should not exceed 2.17 billion.

JCE animation plays but no VFX.
 - Check that the payload interpreter is working properly.

Will you support anything other than MCO? (Vanilla, SKYSA, ABR, etc)
- [Forced animation speed of MCO] If the attack speed is not the default, the sync will be broken, so I have no intention of officially supporting it.
However, if you rename the hkx file to match the animation you are using, you can use it even if you are not an MCO.
Now all you need is Nemesis system and it should work.
