sub-frame rendered output?

[gimiky]

does anyone know if it's possible to get vray to output sub-frame images? even if the time range is set to frames:ticks in 3dsmax, images are still only written once per frame.

i'm sure there are other factors involved, but i noticed the scanline renderer can be set to output subframes via script so it got me wondering.

You can render sub-frames through MaxScript (through the render() command), in the same way as with the scanline renderer, e.g.

render frame: 0.5

will render a frame in the middle between frames 0 and 1.

thanks for your response, vlado.. this works when rendering single frames, but i can't get a sequence to save an output file more than once per frame. i imagine this would require scripting the render command in a loop to update the output file and frame time..?

It appears that you cannot specify a sub-frame interval between the frames, but you can render frames 0.2, 1.2, 2.2 etc, then 0.4, 1.4, 2.4, then 0.6, 1.6, 2.6 etc.

i don't see a way to get output named automatically either.. no matter what fromFrame and toFrame are, filenames are always sequenced as whole frames. i think this will require a script loop.

also, will the render() command automatically use all vray parameters as they are set in the UI?

Yes, it should do that with the exception of the parameters specified in the V-Ray VFB itself, if you use it (like the color curves etc).
