Hello everyone,
I am doing a tool to pack textures into unreal engine (5.1).
To make this tool I am using blueprints following those steps :
- Create render target (create in blueprint not referenced in variables)
- Transfer data to material
- Transfer material to render target
- Transform render target to texture (I don’t store generated texture into variable)
I am doing those steps by pressing a button in editor (no runtime, no tick) via editor utility widget.
I noticed that the node ‘Draw material to render target’ is killing my VRAM on a 4K render target.
The blueprint make it works but this causes the editor to freeze every 5 seconds (No impact on framerate).
Is it normal behavior for this node to consume VRAM even when the operation is over ?
My only solution is to restart the engine.
Here are screenshots, before pressing button 2.3Go VRAM, after pressing button 7.2Go VRAM until I close the editor.
Thanks you for answers.
