Loops out of Range

[im_thatoneguy]

Is it possible in XMesh Max to loop an xMesh loader out of range? So it goes 0-100, 0-100 etc?

This isn’t built into XMesh, but I think you can get the same effect by doing the following:

First, we assign a sawtooth wave to the XMesh Loader’s Playback Graph:

1. Select your XMesh Loader.
2. Enable Files rollout -> Timing -> Graph.
3. Select the Graph Editors menu -> Track View - Curve Editor…
4. In the Track View - Curve Editor window that appears:
   [list=1][*]In the left-hand side, click World -> Objects -> Object (XMeshLoader) -> playbackGraphTime
5. Right-click playbackGraphTime, and choose Assign Controller…
6. In the Assign Float Controller dialog that appears, choose “Float Script”
7. A Script Controller dialog should appear. In the Expression field of the dialog, enter the following:

halfFrameT = (1.f).ticks / 2; period = (101f).ticks; (mod (T + halfFrameT) period) / TicksPerFrame - 0.5

1. Press the Close button.
2. Close the Track View dialog.

Next, we adjust the renderer’s motion blur settings, so that the renderer won’t step across the sawtooth wave’s sharp drop while it is rendering a frame. Based on your other post I assume you are using V-Ray.

1. Open the Render setup dialog, by selecting the Render menu -> Render Setup…
2. In the Render Setup dialog that appears:
   [list=1][*]Switch to the V-Ray tab.
3. In the Camera rollout, find the Motion Blur settings.
4. Change Duration (frames) to 0.99 (or some other value < 1)
5. Change Interval center to 0.0.

Now your XMesh Loader should loop over its frame range, and its motion blur should appear correctly.
