Awesome, glad to help!
Yeah, it’s easy, though my example was overly-complicated. Basically just:
- Set view and projection as you would normally
- Enable render target
2.5. Normally—render.clear(), In this case skip it to make trail effect. - Draw stuff
- Disable render target
- Set view and projection so quad model for render target fills the screen
- Enable render target texture
- Draw render target quad model
- Disable render target texture
