Thanks.Finishing render,to save as image which is error. It said"bryce7.0 has stopped,which an issue causes this". My pc cannot run bryce7.0? win7x64,8G RAM,opengl 4.1.

And I find that when it rendered,a render's vertical line sometimes canot be find,whatever it finished at 100%. Render quality that I check"super". But Render quality that I check"normal" is the same issue. I render sky.
