We have Vray 2.0 and Max 2013 running on 6 machines and they all have the same issue since day one of installing 2.0. In very basic scenes everything acts fine. But in more complex scenes with more geometry, materials, proxies, etc., there is a few second delay when clicking into the Vray Frame Buffer. After the delay, the frame buffer acts just fine and responsive. But once you click back into your viewport or anything in Max, there will be a delay again the next time you click into the frame buffer. Sometimes during the few second delay, the frame buffer disappears entirely before reappearing and becoming responsive. In the worst circumstances, the frame buffer flashes, appearing and disappearing many times, and you have to wait as long as a minute before it stops flashing and allows us to use it again. We haven't been able to determine what makes it behave better or worse other than that it happens most often in complex projects. It's extremely frustrating and really slows us down once it starts behaving this way on a project. If anyone has had a similar problem or could help us shed some light on the issue, that would be very much appreciated.

These might work well in one person shots, but if you filled a room with these people, you'd have an image full of people with their arms crossed and no one talking. This is the same issue we have with the Vizpeople collections. There needs to be more options with people interacting.

Ok so it looks like my suspicion was correct. For those running into this same issue, here is my solution, but please feel free to comment. If you are matching a vertical orientated shot, input your photo dimensions for the render output. Then take your vertical dimension and divide by your horizontal dimension. This number will be the zoom factor. Lastly, take the focal length that the photo was taken at (correcting for crop-frame sensors if necessary) and multiply that by your zoom factor. This will give you the proper focal length for your 3d camera to match into a vertical orientated photo.

I agree with all the previous posts. But also a big problem with many entourage collections, such as VizPeople, and these models, is a lack of interaction. It's tough to compose a shot that feels lively if everyone has their arms crossed and no one's talking. (Or in the case of VizPeople, if everyone is on a cell phone or laptop)

So we are using a vray camera to match our model of an existing parking lot into a photo of the parking lot. We shot in RAW so we know it was taken at 18mm but on a crop-frame sensor so we should use a focal length of 27.46 to be exact. Well, with these settings, our match isn't even close. It wasn't until I put the focal length at 42mm that everything matches perfectly (camera location, light poles, parking islands, etc). So this makes no sense to me. How can the focal length of the vray cam be so far off of the actual photo? The only thing that I can think of is that the photo was taken in vertical orientation. My vray cam isn't vertical orientated. I'm using the output resolution to make the frame vertical. Could I be correct that my vray cam is essentially having to zoom in on the vertical orientated frame forcing the focal length to be larger? Has anyone had to deal with this issue? Thanks for any incite! Jared
