Thank you, Mark_wilkins. Two days ago, my friend and I visited the website www.aliaswavefront.com, there were four kinds of software, Maya; Maya for Mac; Studio Tools; PortfolioWall. no Maya for Linux. A firend told me: "Alias/wavefront company said that 'Customers wishing to purchase Linux or IRIX versions of Maya should contact a local reseller'". Thank you. Best wishes.
