ID 241838 - ScanlineRender spherical projection produces incorrect output when rendering particles from certain camera positions

Follow

Problem summary
When rendering particles using a ScanlineRender node with projection mode set to "spherical", the output is not always a correct spherical image (depending on the camera position).

Please see this example:

Input 1: Wireframe of a sphere


Input 2: Particles emitted from a sphere


Output 1: ScanlineRender of the wireframe sphere produces a complete spherical output


Output 2: ScanlineRender of the particles produces an incomplete image.



Customer reported version
Nuke 9.0v8 and 10.0v2

Customer reported platform
Windows 7

Steps to reproduce

1) Open the attached script.

2) Look at the ScanlineRender output, which shows the complete render of the wireframe sphere.

3) Disconnect the Sphere2 node from Scene2 and look at the updated ScanlineRender. Even though there should be a particle on each point of the sphere, not all of them are rendered.


Reproduced by support
Windows 7: 
NukeX 7.0v10,
8.0v1, 8.0v7, 
9.0v1, 9.0v8,

Mac OSX 10.012 (Sierra):
7.0v10, 8.0v6, 9.0v8, 10.0v1, 10.0v4


Expected behavior
All particles should be rendered in the scanline render.

Actual behavior
An incomplete image is rendered.
