Problems With Zblur -help!-

[user_deleted]

Hello to everybody!

First of all, I have to say that my english is not very precise but i hope that you'll understand what I want to comunicate. (Sorry!!)

So,

I have a 3D render of a room with it's ZChannel.

I want to apply a ZBlur to match the depth of field of the camera.

--

Problems:

Everything works perfect with high blur values. But when I reduce it, a "blend or mix" between blured and non-blured image emerges. I have tried it with ZBlur and IBlur without diferent results.

I think the problem is caused by the antialiasing of the ZChannel. But If someone has any suggestions, please, let me know.
We're working with shake 4.1, and all 3D comes from SoftimageXSI.

Any tip is welcome!

Here you can download the footage images:

And here you have a result of the bad blured image:

make sure your rendered images were not at the same z depth to start with. try using the multiplane node and pulling your your components to different depths. im not sure if this will work because im not at my computer at the moment, but i will try messing around with it for you.
