timewarping imported bin
Posted: Thu Oct 15, 2015 6:13 pm
I am using a scene timewarp in Maya to do a varispeed effect that goes from normal to super slow motion and back. Was hoping that the imported bin mesh would time warp along with the rest of the scene. It almost does...
The mesh interpolates but it is steppy during the slow parts so it is interpolating between the steps, just not correctly. There is constant movement on the mesh during the slow parts but every n frames it jumps, as if the interpolation is getting 75% to the next cached frame but has to jump to make it that last bit.
Is there a setting or method that will correctly interpolate the velocity of the mesh to be able to slow it down below the frame rate it was cached at without the jumps? It is so close to working.
If not I was going to raise the fps in MentalRay hoping that the imported sd animation from maya will stretch properly for the sim, cache at the higher frame rate, and then reimport mesh, but I am not sure how to handle the frame conversion and subsequent scene timewarping in maya.
Playing with the Motion Blur Multiplier on the realFlowMeshSource node has an effect on but unable to eliminate stepping, higher values makes the stepping more obvious, and a value of zero eliminates all interpolation. A value around 2.25 is the best so far but still stepping.
btw- A test of timewarping an imported particle bin works fine.
