I looked at the platform support for Creo 4.0, and it says that the latest version of Windows 10 supported by Creo 4.0 is 1909. Its possible that the graphics card has a different driver in Parallels, but thats purely speculation. Now render the final image and you'll have a white background instead of black. I do also have a different graphics card listed in the OpenGL Renderer as I am on a different machine. Click on one of the walls and set the color to white, do the same for the ceiling and floor. Close that dialog and click 'Modify Room Settings' on the render toolbar.

To change the background, click 'Modify Render Settings' on the rendering toolbar, and then check the 'Render Room' box.

The default background color for rendered images is black. Click 'Render Final Image' on the toolbar that pops up and see the difference! If you do a screen capture now it is going to look so much better.

You can dramatically improve the way your models appear directly onscreen by using Photorender: View -> Model Setup -> Render Control. If you are one of those people (like me) who are constantly taking screen shots of your ProE models to paste into PowerPoint, etc, then I have some good news for you )
