I have updated the Progressive Rendering script. You can download the new version on highend3d by following this link:
Here is the link to download the script on the new creativecrash.com sit (prev iously highend3d.com)
The main change is the render window integration. I have added an icon directly in the render window to enable or disable the Progressive Rendering
You can also display the Options UI by right-clicking the icon
I hope you like this update.
Good progressive renders to you all :)
