Please help me out with this. Colour pallete in model is different than colour pallete in render.
This happened only on this one PC but other programs work fine, the tech service checked.
Which graphics card is SketchUp using on that computer? Look in SketchUp’s Preferences>OpenGL settings. If this is SketchUp 2015 as your profile indicates you are using, it hasn’t changed in more than 5 years so you need to look at what has. Most likely it’s a graphics driver change–possibly due to a Windows update–or the integrated graphics card has been set to be used instead of the Nvidia card.
I did as you said, thank you! Now everything is ok.
