ID 251999 - Illumination render outputs increases render times and improves Final Color render quality.

Problem summary
Illumination render outputs increases render times and improves Final Color render quality.

Customer reported version
modo.13.0v1

Customer reported platform
10.14

Steps to reproduce

1) Launch Modo and open the attached scene.

2) Select Render>Render and view the output.

3) Go to the Shader Tree and select the Illumination (Indirect) output, disable it.

4) Select Render>Render again and view the output, notice the difference between the two.

Expected behaviour
For the Illumination render items not to affect the Final Color render output. This shouldn't happen without notifying the user either via the tooltips or docs.

Actual behaviour
The Illumination render items affect the Final Color render output.

Workaround
I'd suggest using a different render output such as the diffuse shading output if you encounter this issue.
