Unreal 4.25 - Draw text to canvas does not get refreshed

Question

I setup a texture to have text rendered on it with Draw Text

it works once, but never gets refreshed

so I try to force it with Event tick, but it does not work

in the example below, I add a random char to the text buffer, it also works only once

the next iterations does not update the texture

what am I missing ?

thanks for your help

Answer 1

Unreal needs a way to know when you are done drawing on the canvas so it can perform the update. That is what BeginDrawCanvastoRenderTarget and EndDrawCanvastoRenderTarget are for.

All you need to do is wrap the draw command(s) you would like to use in those nodes, and that will work perfectly fine.
