Better Bongo animation support without loading the complete scene for every frame

Bongo is a pleasantly easy-to-use animation tool, but it is a problem for complex scenes that the entire scene is reloaded for each frame and not just the position of the moving object in memory is updated. This means that loading the scene takes longer or just as long as the rendering itself.

This is a wish I have had for years and has become even more urgent with fast multi GPU rendering.

    Hello,
    I am very happy about the new integration of Bongo. It's great to avoid the scene loading time per frame and to have motion blur. Thank you very much!!

    I think some things could be improved.

    (A) When the user presses “Get Animation Range”, the current active range could be set and not the whole timeline range.​

    (B) The time segment “Frame Range” could better be named “Tick range”, as the Bongo Timeline does not display frames. The user uses _BongoRenderAnimation to define how many frames he wants to receive for the tick range of the animation. At the moment it's confusing since an animation can have 30 Bongo ticks which write 250 frames.

    (C) When the user presses “Get Animation Range”, the current active range could be set and not the whole timeline range.​ For example my animation is set for 30 ticks, than V-Ray should take this count. At the moment 99 is used always.

    (D) A great little feature of Bongo that I miss and was one of my big favorites of Bongo is the Bongo option "overwriting existing files". If something is wrong with some frames, I could fix the scene, delete the wrong frames, uncheck that option and re-render the animation. Only the deleted frames were re-rendered. It's a huge time saver to quickly fix small issues or restart a stopped animation. Would be great if V-Ray also could check for exist rendered frames.

    (E) Enhanced motion blur control is missing. I would like to have the motion blur effect as a blur behind the movement. I found an example video for mental ray here. Would this also be possible with the V-Ray Bias option? If so, then it would be nice to have the advanced options available under Advanced Camera Parameters.
