Hi there

I'm new to Keyshot as i only started using it 2 days ago and so far i have found that it is not the easiest of software's i have used. So far i have found that you have to apply colours to your models in the CAD system (SolidWorks) first to define different materials per parts. Bit of a pain but iv got over that!

The problem i'm having now is my model materials keep showing up in some weird black and white pattern? Why is this?

Please any help would be appreciated.
