Problem summary
Renders differ when using Foundry SSE ray tracing when compared to Nvidia and Intel.
Customer reported version
modo.15.2v1
Customer reported platform
windows10
Steps to reproduce
1) Launch Modo.
2) Load attached scene.
3) Go to Render Layout.
3) Select Render Item in the Shader Tree.
4) Go to the Settings tab in Properties.
5) Set Renderer to mPath and ensure that the Ray Trace Engine is set to FoundrySSE.
6) Press F9 to render the seen.
7) Once render is complete save the image as a jpeg and close the Render window.
8) Go back to Properties > Settings and change the RTE to IntelEmbree and render/save the image.
9) Repeat the process for NVIDIA Optix RTE.
10) Looking at a comparison of the images it should be noted that the FoundrySSE image appears to be off from the other two with differences in shadow and scattering distance on the clear orb and red glass orb.
Expected behaviour
The Race Trace Engines should have closer capabilities when the seen is rendered.
Actual behaviour
There is a noticeable difference when using Foundry SSE ray trace engine.
Workaround
Unknown.
