View Full Version : mr and subdiv tesselation in batchrender

I have some simple cube rows combined and applied a sudiv approximation node. Now I render a turntable of the object. In the first frame everything is smooth tesselated. Subdiv approx node uses "Length/Distance/Angle" setting with viewdependent and a distance of 10.

It seems that the tesselation is done only for the very first frame because in the turntable everything is smooth in the first frame, but is extremly low tesselated if some distant parts come closer to the camera.

Does mr for maya only tesselate the first frame?

I think it's the value that you put in the "Length/Distance/Angle". Try to adjust this value so your displacement look gook in close up then render your animation. If it's still not well tesseleted try without view dependant or use parametric method witch is more heavy but more predictable.

Mistake by me... I set the "length" parameter to 10, not the distance.

The values work fine for all interactive renderings. The problem is independent from the settings. The problem is that in batchrenderings the non deformed objects are not retesselated. Try this:

- Create a cube
- Make an animation in direction of the camera, so that the cube is close to the camera at the end of the anim.
- make an subdiv approximation node and set the values to lenght/distance/angle and set length to 20 and the maxsubdiv to 5. This way the cube should be quite round at the end of the animation.
- now render the anim and see whats happening... the cube keeps its tesselation during the whole anim, it is not retesselated.
