Does anyone know how to remove backgrounds from images in LightBox mode. I saw that this feature was available in the Zbrush promo video. I can’t find any information on how to do this. Any feedback is greatly appreciated. Respect.
I think you mean SpotLight. 
And have you read the New Features PDF found in the Documentation folder of your ZBrush 4 installation?
Wow. Great response time. Thank you both very very much. I am sorry for the mix up. Yes, I meant spotlight :). The document and movie was exactly what I was looking for. Thank you both very much. I am new to Zbrush. Great community and excellent communication. Much respect.
