Camera Blur for Still Shots?

[hereagain]

How do you set up the Vraycamera camera blur for a still shot? All I want to do is show a vehicle crossing an intersection, but make it appear as though it was shot with a slow shutter speed. I have no idea how to set up anything that requires animation in Max, f.y.i. As always, thanks for the help.

Depth of Field aka DOF is easily achievable without any knowledge of animation...but a motion blur will need some motion.

 

Quite easy to set up under your camera settings in your render window.

 

To animate -

 

Place your car in the starting position.

 

Switch on 'Auto-key' button at the bottom of the screen. Then move the timeline slider to frame 100 right at the end, then move your car to its ending position and press the icon with the picture of a key on it. Now switch off your 'Auto key' button.

 

Now if you move your timeline slider left & right you will see your car move back & forth, now position your timeline slider so it shows the position you like most for your shot.

 

This means the car is in motion now, even though it is standing still, so now your 'motion blur' settings in Vray: Camera will work, just tweak them and do some test renders.

 

I hope this helps

Thank you sir, I'll try that ASAP.

Worked like a charm.I attached the rough draft for reference. Like you said, i'll have to play with it to get the exposure i'm looking for, but its a start. Gotta love Vray...

Nice one!

 

I'm glad I was able to help

I love Vray too... but you know you don't need vray to do that? You have been able to do that with 3d studio since around 1995.

Well, it was going good. I inserted another vehicle, set the keyframes....now everytime I render, even with the motion blur disabled, i'm getting a black frame? Tried restarting Max, still doing it. Can I reset the animation settings back to stock somehow? Thanks.

Ah hereagain

 

I only read about your problem now, I see you already found help in another post.

 

This situation doesnt sound normal though - remember to always save backup copies especially when working with animation.

[hereagain]

Yea, i'm usually pretty good about backing up, but I slacked off this time. Its an odd problem; if I render from the Vraycamera viewport, its black, but from any other viewport it works. Did the same thing on another computer too, so i know its not just this one. Something with the animation and vraycamera? Oh well, at least it works from the standard views, was worried for a minute there. Thanks for the follow-up.

Are you using exposure on your camera? If so, your scene is probably underexposed since it renders normally with other viewports. You have two choices:

 

1 - change your lighting for the correct exposure

2 - turn of exposure and leave motion blur on on the camera.

 

Remember that with the vraycamera motion blur is controled in the camera not the render panel.

Thanks Chris, you were right - I unchecked the exposure and it rendered fine. I need to make a checklist of all the options in Vray; I get lost in there sometimes.
