Unexpected Forward Vector

Hello everyone,


I'm having issues on getting the forward vector of objects.

The image below is a custom mesh printing the forward vector.

Here's another image that uses a mesh from the Sansar store.

The two objects seems to be printing their forward vectors as world space down.

Now here's another object that's from the Sansar store:

Now this object is printing the forward vector as world space forward, which I am expecting.


Am I importing my models incorrectly or there is something to consider for determining the forward vector? Also what is the W dimension being used for?
