Khai I congradulate you that you know your stuff and everything you say may be correct. Then answer my problem I am having with P6 that have been posted in a number of places in the forum as well as CL tech support that did not come up with what you have explained. The problem is i create scene that contain in access or 4 figures fully kitted out P6 fails to render with error messages like the one mentioned above as well as cant find textures when in fact it staring directly infront of the application. Tell me what you think is the solution when you are getting these types of errors. That would normally work without any problem with its P5 and P4. I have 4 HDD totalling 16G of page files. Before you say the Windows maximum limit 4g I am aware of it. Application dynamics is not our forte that CL techs business. CL have states this is a memory leak and they will resolve it with the forthcoming update.
