Users reported a problem when using Arnold in Houdini 17.5 to render lights effects. We are in no way experts in Houdini or Arnold in the IT department, so we can't really resolve this matter alone.
We first opened a ticket through Autodesk Support but they asked us to come here with the question.
Here are the steps used to create the problem
- Create a new project
- Add a sphere on the middle
- Add a grid under it
- In Arnold Lights, select Distant and add it in front of the sphere
- In the out section, add a Render-> Arnold output object
- Save the project
- In Render View, click Render
The result is just the sphere and the grid, all in white, which users report should be different. (See images)
We also generated a log by adding the log to file option with log verbosity to Debug: logarnold.txt
