Hello, Ok....I'm currently doing some rendered walkthrough right now. I have a total of 1650 frames, 25 frames/hour, (total of 1 min. and 6 sec. of walkthrough), my setting was set to modified-"low" res. (bump up the anti-aliasing a notch - and that's it, well except that I also turn on the portals). Also, size is 6" x 4.5" (default). My question is... I'm only averaging 3 frames per hour, if my calculation is correct, it will take about 23 days (24 hours a day) to finish a low res rendered walkthrough. I have an Inter Core 2, 6300 @ 1.86GHz, 3gb RAM. Thanks in advance! -Grinheart "Call of Duty 4 MW anyone? - PS3 - Add me"

follow up on my previous post.... would it really take that long to render 1650 frames on 25f/h. considering it's on the modified low resolution too. I heard that Interior rendering (which is the one i'm working on) would take more time to render than exterior. But even so..... 23 days!!!! Tips to improve are always appreciated. Thx!

1650 frames is going to take quite a while to render, particularly with 3gb RAM. If each frame is taking 20 mins it would seem like quite a long time for a low res render. Make sure that you only have lights on that are required for the scene. You may want to save a copy of the model and strip it of everything that will not be seen and use a scope box to limit the size of the model to only include what will be rendered. Have you tried something shorter yet, such as 200 frames at that quality to see how it turns out? You may find that the low res rendering is not worth it. You can do a shaded rendering very quickly.

Thanks Tim for your reply... No, I haven't try a shorter frames yet with the same settings. It's just that I started the rendering process already and I have a deadline. Actually, I'll be a week behind already with this 23+ days of rendering. I just didn't want to cancel it and tweek it a little bit to go faster. They bought a new computer for me but it won't be here in the next 2 weeks - It will have an 8gb RAM and i sure hope that helps. I'll try a shorter frames later on. Thx again!

Pretty good GRINEART, but it seems that in some scenes you lose the control of the camera..........Of course I know it's your first walkthrough

Looks good minus the motion of the camera and some light pollution. grinheart i seriously urge you to look into 3ds Max, once you become proficient in Max you could produce a higher quality walkthrough in a fraction of the time. my farm can do a few thousand frames a night and its not hard to accomplish that.

Thank you guys! ya... I think I was a little drunk when I was holding the camera. LOL. Anyways, ya... been wanting to try Max (got the CD trial) but never got a chance to play with it. I wonder how hard/easy to set up the camera walkthrough in max? too bad you can't export the walkthrough camera from Revit/FBX to Max. Also, do you have to do the lighting in max or in Revit? Will Max take the lighting from Revit or not? Let me know... Thanks!

max will take all your lighting and materials. Animating a camera in Max is so much easier and it produces something of much higher quality. I'll post a short video that only took me 16 man hours from start to finish.

Pretty interesting, but I don't like the stars in your intro, seems like a Walt Disney movie intro and I think you should put an instrumental music instead of the background song you have put in your video.......

If I'm going to do a Walkthrough Rendering in 3ds Max (animating the camera)... What Views do i need to export (3d default view or the perspective view - created by camera?) to fbx so i can do the walkthru animation? I understand that you can only export one view at a time to fbx. pardon my ignorance on 3ds max - I'm just thinking of trying it out. Thanks.

export the camera view you like not the default 3d view. In Max you can draw a spline and attach your camera to it as your camera path. its a little confusing at first but once you get the hang of it you'll be able to create more realistic wlakthroughs in a fraction of the time.
