Using Projected Texture effect width collada imported mesh and camera

Hi, i’m trying to make a planar proyection over a mesh.With Projected Texture Effect.
I have imported the camera and the mesh into vvvv via collada. Then importing the texture and apply and aspect ratio transform but it doesn’t fit.
And i also tried transforming the texture with sliders.
Im rendering the image and exporting the collada file with C4D.
My image is 800x600 pixels.
Any ideas?
