Version v1.2.38


 NEW FEATURES


 FIXED

 When geometry is imported with SOP Import, the 'v' (velocity) attribute is transformed by default. 

 As a result, if the procedural is later applied to an object with a 10× scale in Solaris, an original velocity of 20 m/s becomes 2 m/s, which is mathematically correct at that stage. 

 However, renderers such as Arnold and Karma also apply the current transform to velocity, width, and certain other attributes during rendering. 

 Without compensating for this, the velocity would be scaled a second time, resulting in incorrect motion blur.

 By multiplying 'v' by the inverse of the USD transform inside the procedural, the renderer's transform restores the correct velocity. 

 This change also ensures that rotations and translations are handled correctly.


 IMPROVED

 For deform motion blur to work correctly, the animated mesh must be cached, and the render settings must reference a valid camera.
