Keyframes exported incorrectly

[enrique.monzo]

(This topic has been already posted in V-Ray for Blender :: Custom Build)

I created a very simple scene (50 frames) where I animate the rotation of a cube as follows:

- Frames 01..10 ==> Cube not moving
- Frames 11..30 ==> Cube rotating on the Y axis
- Frames 31..50 ==> Cube not moving

Blender file: motion_cube_00.zip

Screenshot of the animation scene:


Since I also want to generate the Velocity channel render for blur motion in post-production, I set Render-->Animation as Animation: Full range (so the velocity channel is calculated properly).


This is the result rendering the viewport in OpenGL (cube not moving in 1-10, moves in 11-30, and not moving in 31-50):


But after rendering the same frames with V-Ray, I observe that the cube is already moving in the first frame, when it is supposed to be still:

It seems that the first keyframe (located at frame 11) is moved to frame 1 when exporting.



Using:
- Latest build for Windows (27-03-201
- V-Ray Standalone 3.60.04

New test, using a simple scene where the cube moves in steps along the x-axis:



Frames 1-4: not moving
Frames 5-8: moves in x-axis
Frames 9-12: not moving
Frames 13-16: moves in x-axis
Frames 17-20: not moving
Frames 21-24: moves in x-axis
Frames 25-29: not moving

Viewport render in OpenGL:


Animation rendered with V-Ray:


Once more, the cube is moving during the frame ranges that is supposed not not move.

Thanks for the report, we'll fix this.

enrique.monzo Thank you for detailed scenes, this should be resolved with next nightly build.

poseidon4o bdancer I just checked it and it is working great. Thanks a lot!
