Material Domain User Interface has less options?

Am making a material using a render target that I’m putting into a UMG. I have to make the material domains into User Interface for it to accept the material. But doing this changes the material setup nodes. Now I can’t controller if my texture is fed into the colour vs emissive nodes etc. and it’s causing me issues.

Anything I can do do mitigate this?

well it s because the UI material domain is unlit and 2d, so lots of options are not accessible.what do you need access to ?
