Hi Skryder

Some notes
To apply colors and materials
- you must be close to the element to be textured
- you can texture or apply color through a door or window (even if the door is open or the glass looks transparent, the wall is still there)
- If you are working on a surface under the 0.00 level, you must set the elevation of the yellow (or green) man as negative. This means that if you floor elevation is -96, the elevation of the yellow (or green) man must be, for example, -60. Set the elevation double clicking on the yellow / green man

If all of the above fail, then check for a video problem in your computer--> go to the website of your card manufacturer and update the drivers

Lets us know if you need additional help
