Draw the picture with another program

The picture in Render is drawn by our own engines: Fast and the Path tracer, in the browser and in CadCraft Studio. Another program can draw it only when a render-engine add-on brings it: see Add a render engine with an add-on. To take the scene to another program and keep working there, use Open the scene in another program or Send the scene to a game engine.

Draw a picture with an add-on's engine

1. Turn the add-on on in Settings › Add-ons. Its engine appears in the Engine list of Render.
2. Choose it. Its own settings show under the Engine list.
3. Click Render. In Studio, the first time an add-on runs a program, Studio asks you in its own dialog. Progress shows while it draws; Stop ends it. The picture appears marked with the engine that drew it.

An engine written in JavaScript runs in the browser too. An engine that runs a program on this computer runs only in Studio; in the browser it shows as a file to save.

What is carried over

The engine gets a package: the model as a USD file (and a glTF file when it asks for one), and a settings file with the exact material values, the sun and the sky, every lamp that is on with its power and light profile, the camera and the exposure. Each program lights, tones and samples in its own way, so pictures are alike in camera, sun, lamps and exposure, not pixel for pixel.

Programs CadCraft never runs

CadCraft never starts a program under the GNU GPL licence, and never lists one as an engine or an Open in target. Blender is one of them, so it is not in the Engine list. A USD or glTF file saved from Render still opens in it like in any program that reads those files.
