Set light function parameters from blueprint?

Hi all.

Just wondering if it’s possible to set parameters of a light function material from within a blueprint - and if so, how? I was hoping I might be able to tweak parameters during run time in the same way as with other dynamic material instances, but I’m having very little luck so far.

Any help / advice would be massively appreciated!

Thanks for your time,

Currently you would need to use a Material Parameter Collection for that as I don’t believe there is any interface for creating MIDs for lights.

Thanks - I didn’t realise Material Collection Parameters were a thing, but they seem like the ideal solution as I was hoping to synchronise the parameters across multiple materials in this case anyway.

Also just wanted to say how impressed I am to have received such a prompt and helpful reply from an actual developer of the engine.

Cheers!
