Are you able to run in Pixel Shader mode with all other graphical options turned on?

Make sure that Anti Aliasing isn't being controlled exclusively by your graphics card settings. You would normally want to ensure that you allow applications to control this setting.

Also make sure you have updated your graphics drivers to the latest available. This may help too.

A little more info about your system specifications, including graphics may help to diagnose the problem if the above doesn't help.

Thanks for supplying more information. It would certainly seem the Intel Graphics are the most likely cause of the anit-aliasing problem. While later models of Intel Graphics do support Pixel Shading they are not the best for 3D work and iClone will disable the anti-aliasing option if it isn't found to be fully supported.

If you would like further assistance, you can send a Support request using the link below. Technical Support will look at your DirectX log to see if your system can support this feature.

Thanks. 

That's a nice tip, because even with anti-aliasing on there seem to be artefacts sometimes. You just need a lot of disk space...
