Spotlight barn door options

Hi,

I need to emulate a barn door on a spotlight but I can’t find if anyone has done this yet in unreal. I was planning to emulate this in a simple blueprint to emulate the way this works in Arnold (https://docs.arnoldrenderer.com/page…pageId=1081910) by controlling some simple geometry in front of the spotlight … but before I start, does anyone have any advice? Is this the best approach? Can I use existing spotlight settings to achieve the same result without using blueprints? Would IES profiles help me in this regard?

Thanks.

Personally my first thought is to use light functions, Light Functions | Unreal Engine Documentation
