Hi Everyone, I have a couple 3ds/ipas questions. 1. Will meshres allow me to control the complexity of models at render time? What I thought it would do is allow me to simplify a very complex model (using optimize) a number of times so that I'd have say 6 models of varying complexity. Then I'd somehow embed these 6 models into the original mesh and select at which frames during my animation they appear. This way when my complex object is 10 miles away I use the highly simplified version, when it fills the camera view I switch to the more complex version. If this IS how it's meant to work, how do I enter the frames at which various models are used?? 2. Can anyone explain how to achieve what I think is called a depth of field effect? I basically want to focus on an object on a tabletop, with other objects in the background out of focus. Then I need to focus on the background objects without moving the camera or adjusting the lighting. What I'd like is a smooth transition from blur to focus – a little like distance cue but not only calculated radially from the camera POV but the ability to focus on a single object with everything around it blurred. Can I achieve this with Studio, or does anyone know if it's being/or has been addressed with IPAS3? Thanks, Andy Roberts BITS Corp.
