Update blueprint on parameter change

Hi guys,

I want to create my own little light manager for my scene.
For this I created a parameter collection and whenever I change the values, the intensity in the blueprint is not updated.
Well, they are, but the blueprint itself does no update, because unreal does not see the why it should do so.

So my question is … is there a possibility, that the blueprint looks on these parameter collection and recognize changes? If not, how can I build up a global ‘force refresh’ button?

Thanks for your help :slight_smile:

When you update the parameters, you need to call an event in the light BP to get it to re-read the parameters.

I don’t know exactly how you have this setup, but if you had a BP changing the params, it could call the update function in the light BP.
