Hi! Why does the brightness of the 3D view decrease when the laser zone gets bigger? I’m working with two 20W units, and I need a wider laser spread. That’s why I can’t preview most of the clips.

Any recommendations?

Thanksss!

I think it’s just a artefact of the way the system renders laser beams, but don’t worry you can compensate with the brightness setting in the 3D Visualiser Settings panel.

Hope this helps!
