Short answer: currently there's nothing in the alphas about a new renderer.
I think to make that happen someone will need to be recruited who completely understands how A:M does what it does in every way and also completely understands how your target renderer does what it does in every way and can program fluently in both of them. And that person would have to have a lot of time available.
Currently, the path to using another renderer is to export an OBJ series or an MDD (point cloud?), right?
We had something like bucket rendering in v14 (it was horizontal strips rather than a grid) but it gave inconsistent results in complicated scenes.
Possibilities to try...
-Copy the whole model into a new model window
-Save PRJ, restart A:M and reload
-Save PRJ, do Help>Reset Settings, restart A:M and reload
That link is written right in your post but for some reason it is getting bad characters added to the end of it. I'm not sure why that is. For anyone wanting to try the link, shave the "%u200B" off the URL after you get a 404 error and it will work.
That is ominous! I was waiting for him to get zapped.
I like the slowly moving camera shots, they add depth to the scene.
Is the character all mocap or was there some manual keyframing on him?
