The Personal Learning Edition (PLE) of VUE did exist, but is now updated to version 7. This is the full software, with all functionality, but with some limitations to prevent commercial usage. It exists in a standalone and an integrated version, which can be used with some popular commercial 3D Animation applications: 3ds Max, Maya, XSI, C4D, Lightwave. http://www.vue7.com/ple The PLE is for personal, non-commercial use only, files cannot be exchanged with other PLE users and are not compatible with other versions of Vue, renders may be watermarked and carry a logo. Thank you for reminding me about it, "Xabier Urrutia"!
