Drawing in a Texture in Realtime

Hi all,

I am looking for a way to paint into a texture at runtime and use this texture in a material.
I have been searching for quite some time now on how to do that with blueprint but apparently it’s not possible.

I found this page on the wiki https://wiki.unrealengine.com/Procedural_Materials ,that require some programming, but i cannot get it to work.
The sample is incomplete and require some knowledge of c++ and the complete exemple is referencing code that is unavailable.

Anyone could point me out to a good tutorial, or get some very basic project working with the sample ?

thank you very much

Hey, i put together a simple example
hope this helps.

just to make it interesting, this example runs Conway’s Game of Life and renders it on a 256x256 texture
