Im not gonna rush for this UG as i think its somewhat limited for the price, Blurry Reflections, 3d Motion Blur and Vector Motion Blur should be in a V4 upgrade wether you buy pro or not as I already own Transposer and Amapi 7, plus the Landscape and Sky look a lot like the old plugins from the raydream days. Where are the improvement's to the shader and render setting ie subsurface scattering etc, particles not even touched. Plus the cost. Standard Upgrade 105 for less than 10 additions or Pro for 162, with XSI and 40hrs of tutorials now only 350 (yes 200+ difference) its getting harder to go for these Ugrades take into account that Carrara will need to get to ver 6 before we see resonable cloth and hair inc. FWIW im not going to abandon Carrara as Im very happy with version 3, Amapi 7 and Transposer, V3 is one of the best apps on the market for its specific market but a V4 tag needed more possibly a 3.5 would have been a better title.
