# Adjusting Focus

All the cameras need to have a good and clear view of the projection object. The image also needs to be in focus.

You can adjust the focus rings on the camera itself and while doing it keep clicking on **Refresh the texture** button.

Enabling **Circles and lines** override might help you achieve a precise focus.

**Good to know:** Once you ensure the focus, it is recommended to tighten the screw a bit, so that the focus doesn't change.
