hi, as the title states I’m trying to write to textures per pixel and update them in game.  
I found this article on it but I can’t get it working.  
I can follow the article just fine until I get at the “Dynamic Texture & Dynamic Material” title.  
Here they suddenly use names without declaring them anywhere so I don’t know what to do with them.  
Variables like mDynamicMaterials, mDynamicTexture, StaticMeshComponent etc.  
I figured out a few of them but some just feel vague.

Any help would be highly appreciated.
