Thanks for this. I just modified the Key_Block line in the AliceInput.ini, saved it, and it worked. Block was automatically tied to A so I just held the A button while focused and the Umbrella works.

with controller if you hold A whilst focusing it works

I solved the problem with (translated from german to english)
1. Open with editor: This PC > Documents > (My Games) > Alice Madness Returns > AliceGame > Config > AliceInput.ini
Alternative: C: > Users > (your username) > Documents > (My Games) >
Alice Madness Returns > AliceGame > Config > AliceInput.ini

Change row: Key_Block = TriggerBlock
to: Key_Block = TriggerBlock true | OnRelease TriggerBlock false
and save the file.

2. Open with editor: (Installation-Path) > Alice Madness Returns > AliceGame > Config > DefaultInput.ini

Change row: Key_Block = TriggerBlock
to: Key_Block = TriggerBlock true | OnRelease TriggerBlock false
and save the file.

3. start the game and go to the keyboard configurations > Camera
Use "hold" for target aiming, not toggle that works not as good as hold.

4. in the game you have to hold the aiming key and then hold the block key and the umbrella rotates

I have configured my aiming key to right mouse button and the block key to F.
Works for me.

jesus they couldn't make it a button rpess could they? no, that's too simple

whenever i go into focus mode and aim at the enemy and press the button nothing happens
and sometimes my pepper grinder stays equipped and i cant use my knife or hobby horse
is there a way i can fix this?

How can use the controller?

Es funktioniert nicht. Leider. Ich denke ich habe einen bug der leider nicht so leicht zu umgehen ist. trotzdem danke^^

Its ok. Thanks.

So using the controller you can't?
