xmesh behavior when projected/using extracted exr as texture

Hello,

Noticed bit of strange issues regarding xmesh node in Nuke.(xmeshsource)

  1. When xmesh loads up a simple geo(image plane exported from Max) with animation, it seems to work okay for checker board or constant.
    But, when using an exr image which is plate that has been pre-multiplied with extraction alpha, it behaves ackwardly.

    • Image in the read node differs from output of scanlineRenderer node,
    • When animated in the viewer, it works for some frames and some frames don’t
    • It gets lost in the 3D view mode, the the read node that is connected to xmesh node no longer visible in 3D view and 2D view.
    • When rendered on the farm, some frames will show correct frame, but some will be black frame, and some will have different frame from actual 2D image.
    • Settings were, Read node(Plate extracted and premultiplied with alpha, exr) -> xmesh node -> scanlineRenderer + shot camera
    • When working with geometry itself looks to be working but when connected to larger image data, it starts to break.
  2. Projection also has same issue with above settings + project3D node.

  3. Currently, geometry imported to Nuke, have x axis rotate of +90 degrees, need to put -90 degrees in x-axis to match to Max

The build is : 0.7.3.55730

Thank you,

Thank you for your report! We will look into this.
