I have a project setup with a Sequence that I am able to render interactively with the Movie Render Queue (“Render (local)” etc). I have enabled the HttpListener and remote API on port 30010 and am able to do things like move objects around (in the editor or in the game modes). I want to be able to issue the instruction and send it through the /remote API as a call of some sort in order to cause that render to happen whether the Editor is in Editor or Game mode.
Note that I have been able to “trick” this to happen in Game mode by creating a Level Blueprint that does the render I want in response to an event – I then created a collision setup and trigger that event when an collision happens which I can cause by moving the two objects into colliding positions. This feels a bit hack-y an I would like to be able to more explicitly call for the render to happen.I would have expected this to be a common pattern in virtual production workflows.
Note also that I am also able to run the render on the command line but that brings with it all of the overhead of start the UE4 session with that project for each render and I do not wish to pay that.(This is essentially running the equivalent of the “Render (remote)” command.)
In essence, I want to be able to use the remote API to cause a render to happen at will and with minimal overhead (whether in game or editor mode).
