Hey JLBXB3, I’ve been looking at this for a few days and as I understand it, an entirely different methodology would be needed for 3D widgets due to how this [beautiful] 2D blur was designed.
I created a post on the forums a few days ago fishing for ideas how to create it and while nobody has responded, I’ve still been thinking through how to do this, in my spare time. I’m thinking it could work using either the SceneColor node or through a RenderTarget with some custom shader work to create the Gaussian Blur. All this to say, I think it’s entirely doable but I’m not 100% on the details of how… yet. If you want to work together to get it done, I’m all for it. Maybe reply to my forum post and we can get some more eyes on the problem.
