The sharper image is from rhino 6. Both are using the same display mode (I exported the display mode from 6 and imported iinto 7) Render mode with edges and using scene lighting. They both have the same sun settings and have skylight at .5. the only difference I can see is that in 7 you have to use a custom environment with skylight controls.
It would be fantastic to be able to keep all my envroment displays the same.
any advice
Thanks
