Yep, There are many variables to take into account as to the time taken .....the hardware.....the model size.....materials applied.....the quality ofthe raytrace......the number of frames/second......these are just a few considerations......Remember that these are what ALL walkthroughs in ALL packages have to deal with. The big tip is to first do some region raytraces to see how things will look; and maybe a basic wireframe B&W walkthrough. I remember checking on mine after 5 hours to find i had placed an RPC person on a wrong level. It looked like I had someone jumping from the 12th storey...(...with the walkthrough going around this hanging-in-the-air character it looked like a scene from "The Matrix"!) My last walkthrough was a 28 storey hotel with lots of glass, 1 minute duration. It was one of the 1st projects I did with Revit and one of the things that sold me on it. I did it solo and had the model completed in two and a half days. The raytracing took 36 hours. John Mc (also from Brissie Australia) Post edited on 2006-03-25 23:38:50

Here is a tip if you are short on time but have a resonable amount of resources at your disposal- 1/ I use the save as command LOTS! Save the file into as many different names as you can e.g. house plan1, houseplan 2 etc., etc. 2/ Once you have done this open up each file on a different computer and then with the walk through settings exactly the same on each file you have open, render different frames for each drawing (remenmber that these "save as" files are of the same project & walk through) For example on houseplan1 render frames 1-50, on houseplan2 render frames 51-99 etc. 3/ Once these have been rendered then put the separate rendered walkthrough files back togerther in something simple like Windows Movie Maker ==== Just remember to make all the render settinngs EXACTLY the same in each file so the rendered output will look the same once completed =========== Hope this helps!
