Does slate ui can use any Opengl/Direct stuffs

I found Slate have not any solution to do 3d transform.

But I believe that it connect with Direct/opengl.

does any know Does slate ui can use any Opengl/Direct api to do some 3d transform

Slate itself is a low-level user interface framework. 2D and 3D transformation are currently being implemented as part of Unreal Motion Graphics (UMG), which is built on top of Slate and provides, besides other things, animation and transformation capabilities.

I need to clarify: 2D transformations will also be made available in Slate APIs. We are currently working on this. In-game 3D UI rendering and transformations are also being worked on as part of UMG.

thank you very much
