Issue with importing camera position animation

[mrjrdnthms]

I am seeing some weird behavior when trying to render a sequence of images based on different camera positions. I have a set of 64 camera positions (positions orbit about the origin in a circle). For 3 of the positions the rendering output of Terragen is incorrect. 2 positions incorrectly shift the camera and 1 just produces a black screen. Attached is a .chan file with the camera positions I am importing. Is my .chan formatting bad? Any ideas?

Steps to reproduce:
1. Open default terragen scene
2. Select render camera node and switch to import tab. Import the file "camera_64.chan" which is attached to this post.
3. Jump to frame 17 in animation panel
4. Render image.

When I do this I get a completely black image. No terrain appears.

UPDATE:

So I was able to resolve the issue after doing the following.

1. I ensured FOV props were not animated. Chose constant HFOV at 60.
2. Disabled 3d motion blur in Render quality tab
3. Set Motion Blur length to 0 in Render Camera>Blur tab

I'm not sure which of those resolved the issue but that seemed to take care of it.

I would guess it was the motion blur. I think it can cause unexpected offsets, depending on how the source app treats motion blur and camera position.

If that's the problem, you should be able to fix it and render with motion blur.
