Thanks for 5.0 … looks like a great update!
I’m trying to add motion blur to a physics simulation project. I’m using key type RT_MOTIONKEYTYPE_SRT_FLOAT16 applied to Transform nodes. The border modes, motion range and motion steps are default values. The 1st key is set to the previous transform from the physics engine and the 2nd key is set to the physics engine’s current transform. I’m pretty sure that the math is right in the keys since the motion blur itself looks correct when the objects are moving.
The problem I have is that when an object stops moving, Optix is still displaying motion blur, even though the 1st and 2nd keys differ only by slight round off errors. If I reset the simulation so that the 1st and 2nd keys are the same again, there’s no motion blur from Optix as expected.
In the video, I’m toggling MB on/off by changing the number of steps from 1-2 in the gui.
I suspect this is user error but I’ve tried everything thing I can think of and can’t fix it. Any idea what might be causing this?
