Object Color incorrectly shown in the Omniverse USD Composer

[ FlexSim 24.0.1 ]

Hello FlexSim Team,

I would like to pose a question: do you know how to show object colors correctly in the Omniverse USD Composer? As you may see in the following screenshots, I now can display my model in the Omniverse software program, including item flow and operator movement. However, object colors show incorrectly. Specifically, the colors of the queue and operators would turn white. Attached are relevant error messages in connecting the model to the USD Composer.

Thank you.

Hey @Scarlett X, could you share your model with us so we can take a look at what could be going on? Thank you.

It looks like that in Omniverse there is a different set of light sources.

@Scarlett X, after downloading your files and attempting to replicate the visual errors you're seeing. Joerg's comment is true that the Omniverse light source may cause the objects to appear different shades of their original color. Based on the model you supplied, it seems that it is a different model from the one you took screenshots.

In USD Composer, you can change the type of lighting you get so it looks closer to what you're expecting.

Hi Kavika, thank you for your solution. As shown in the attached screenshot, the color of FlexSim objects continued to be incomplete after I made a few suggested changes to the lighting effect in USD Composer. Error messages are marked in the blue box of the screenshot.

@Scarlett X, I just tried your model with FlexSim version 24.0.1 and USD Composer version 2023.2.2. I saved your USD Stage to a file on a local nucleus server I have on my machine. I made a live connection and ran the model. All the colors seem to draw fine.

You might have uploaded a model different from the one experiencing problems. The screenshots show male operators while the model you linked has female operators. You may have made changes that fixed your issue?
