How to write text to Texture

[CMaker]

Hi all,
 i m working on render to texture in order to build a LCD system in car (dashboard)  and I was wondering how to write text to rtt texture.

Right now it looks like the UI renderer is hardcoded in the c++ code

UI.cpp ln:577  The initializer stuff.

Yes, the UI only knows how to render its fixed element hierarchy to the backbuffer. Generally we're missing utility methods to immediately render stuff in the interest of being efficient (ie. all rendering happens at the end of the frame)

At least what you can do right now is to have a second scene, use Text3D object(s) and render them to the RTT. This doesn't need to update every frame, you can trigger the updates manually when needed.

can multiple ui subsystems be spawned?

At the moment, no. What would perhaps make sense would be to refactor the things from it that aren't truly global, into a class like UIContainer or something, which would contain a hierarchy and handle rendering/input for it, and those could be multiply instantiated.
