Yes, I would describe Maxwell like this.
Here a screenshot how it looks like in Archicad 17:
On the right side the real-time preview called "Fire".
The scene is uploaded, similar to Octane, into the Maxwell plugin and everything happens so far only in Archicad.
If you want to render "properly", the scene is exported then to the Maxwell Render (so there's a difference to Octane):
On the other hand the workflow for animating is again more similar. First you set the render Engine to Maxwell and that's how the settings then look like:
After that, the usual way; Documentation -> Animate -> Photorealistic / don't know the exact english phrases, well here the screenshot
The frames are exported then to the external renderer frame by frame - via the engine defined in the PhotoRendering Settings. So it's the idendical way
like in Octane. And I checked out how it behaves with the fov: it works, fov is definitevely changing! (And it needs an eternity to render of course
)
You think we could ask a question @ Next Limit how they do it?
Today I wrote a long letter to Graphisoft support, so we will see next week what they answer...
Have a nice weekend,
Artur
