is it possible to paint a texture at runtime ?

Hi,

Is there a way to paint a texture at runtime more or less the way it’s done in the editor ?

Plus it would have to be replicated.

The idea would be to make (c++) a very simple white board (just a pen and an eraser) for every client to draw on it.

I was thinking importing a white texture then paint on it.

Would that be a possible stategy, or should i look for a more DrawDebugStuffs oriented way, or anything else ?

I just need some general pointers here, just to know if it’s worth spending time on (i’m a very casual programmer so everything takes a lot of time).

Thanks
