camera trouble

I used a perspective depth camera to render a moving object.but as it moves.I see a lot of residual images.these images overlay on each other.
How did this happen?

 

That's hard to say without seeing it. Can you put your scene in a Webplayer or post a screenshot?

 

How can I insert an image?It is in my PC

 

as it happens hit print screen button which is generally to the right of f12, then go into say paint and paste it and save as image, and upload it

 

click on "Reply to Thread", then next to the "Post Quick Reply", click on "Go Advanced", then scroll down and click on "Manage Attachments"

Then look for "Add files" and upload your file, and then after it's uploaded, click on "Insert Inline"

 

can you see it?

 

the man moves from up to down.
there are 2 cameras in the current scene.
one is perspective depth cam,rendering this man.
the other is ortho cam,rendering NGUI.

 

Yes, I can see the image. Thanks for adding the extra information on what you are doing. More information is always a good thing.

Unfortunately, I have no idea what is causing that to happen.

Anyone?

 

maybe try deactivating the perspective depth camera, and move the character again afterwards, and see if it persists, that way we can narrow down where it is coming from?

 

It's because you are not clearing your color buffer from 1 frame to the next. Check that at least one camera has clearFlags set to skybox or solid color, or ensure you are rendering to every pixel of the screen (say a full screen quad...).

 

You mean not all of them are depth camera?
I fixed some hours ago,by one solid-Color camera,I dont understand it when I did it,now you make me clear.
Thanks.
and thank lockbox and andulvar as well
