@pawel.jarosz21 ever do the PR mentioned here? Render.enable_render_target() seems to not work (and is not in the API)

No, I didn’t made a PR here, however, @britzl said:

I believe that tutorial is outdated. I saw on Slack that someone was going to create a PR to fix it.

Did you find out who was making it?
