Hi Etienne,
Thank you for the file. The output says that CAESES is using software rendering instead of any graphics hardware.
We have two problems now:
1. If the graphics drivers installed correctly, CAESES should not be running in software rendering mode.
2. Even when using software rendering, the surfaces should not be red.
So I have some additional questions:
1. Which graphics card are you using?
2. Are you maybe running CAESES using a remote desktop connection?
3. Could you try clicking on the pencil icon in the lower left of the 3D-Window and then select "Environment/Warehouse with lights" and see if this changes anything or produces error messages in the console?
Thank you,
Erik
