Hello All, Opinions anyone? We're in the middle of a sizeable project completely dependent on the stability of 3DS. The only benefit I can perceive from R4 would by the "real-time preview" feature. This would give us the ability to produce the remaining animation faster by cutting preview time. This benefit would be lost immediately if R4 brings display driver and other problems to the mix. Is anyone so impressed with the fast preview that they would think I'm crazy to delay installing R4 for a couple of months until this project is a wrap? Thanks for the input, Tom
