Does anyone here know if Houdini allows rendering motion blur only on whole integer frames instead of the default sub-frame motion blur? For e.g. At frame 110 it should write the Motion Block for frame 110 and 111 and not 110 to 110.5?
I need to match Mantra renders with Maya/RMS>prman renders which have been rendered with non sub-frame blur. Due to this reason, currently there’s a slight offset between the two.
Isn’t it just a matter of shutter offset? From the help of Mantra ROP:
Shutter offset:
Controls where the blur occurs in the image relative to the position of the object at the current frame. A value of -1 blurs from the position at the previous frame to the position in the current frame. A value of 0 blurs from halfway to the previous frame to halfway to the next frame. A value of 1 blurs from the current position to the position at the next frame. You can use fractional frame values and values greater than -1 or 1 to move the blur less or more.
