Hi,
I was testing the Kit 106.5 usdcomposer (default setting) and notice this issue with rotation using the textbox. I am coming from the launcher version of usdcomposer where its working as intended in this version.
In the launcher version you can key/slider in the value of each individual axis in their respective textbox and it will remain on that value (example X:45, Y:45, Z:45). In the Kit 106.5 version, only the first value key/slider in an axis works as it should but once you input any value into another axis it starts to get crazy and affect other axis when it should not while the rotation like get lock up or something as shown in the recording below.
