You can do this in the begin section of your script:

In Result object with ID 385687 you have a property backdrop_path being null. Adjust your Result object and make the property nullable:

String? backdropPath;

There isn't enough information within your question to provide an absolute answer. It could be down to one of many problems...

1. Are you using expressions?
2. Are you using IK chains?
3. Are you animating rotate or scale pivots?
4. Have you tried baking the animation data first?
5. Are you sure the exporter works?
6. Is the character rig known to work within the game? (or is this your own?)

Typically exporters for games will bake the Maya joint model down to simple TRS animations. Sadly there are some combinations of scale/rotate pivots that are simply impossible to convert into TRS, and still maintain correct animation interpolation. Assuming the exporter works correctly, I'm going to guess that may be the cause?

I think you're thinking of the maximum view distance as being consistently 900 units away from the camera/eye position. If that was the case, it wouldn't be a clipping plane at all, it would be a curve - a sector of a sphere.

In reality the view frustum is a truncated pyramid made up of 6 planes. When the far plane is set to 900, then the view distance for the pixel in the centre of the view is 900, but the view distance at the corners is much higher (how much higher depends on the FOVs - you could work it out with a bit of trig).

So as you turn your camera left and right, an object approx 900 units away from the camera will come in and out of view as it intersects the far plane.

I'm not familiar with the framework you're using, but if it does what it seems, I think you're almost there. Just don't zero out the X and Z components of the quaternion before calling quaternionTwist().

The quaternions q1 = (x,y,z,w) and q2 = (0, y, 0, w) don't represent the same rotation about the y-axis, especially since q2 written this way becomes unnormalized, so what you're really comparing is (x,y,z,w) with (0, y/|q2|, 0, w/|q2|) where |q2| = sqrt(y^2 + w^2).

I think best practice usually comes down to what style suits you best. I don't particularly think there's a noticeable performance difference between these two methods, but perhaps someone can do some simple benchmarking for us.

In a very subjective answer to your question, I personally prefer with-statements. It indicates that you're executing code with a resource that will dispose itself once completed. This is also usually how you execute built-in contexts like when opening a file, etc.

One more added benefit is that you don't need to define a method to run in the with-statement.

However, you can save yourself some effort by using contextlib to generate your context:

Try and set the encoding to UTF-8

For example:

file = open(filename, encoding="utf8")

You can get the value which is next to last non-NA value.
