Camera calibration issue

[khomatech]

Hi all. I'm currently having a problem with camera mapping and texture projection in Octane.

I've calibrated my C4D camera using the Camera Calibrator tag according to the background image visible in the screenshots. I've then placed a cube in the scene and projected the background image onto it using the camera projection option in the material tag.

As you can see, it projects onto the cube almost perfectly in the C4D viewport. Unfortunately, it's projecting incorrectly in the Octane Live Viewer. If I uncheck 'Calculate PP for 3VPs" in the Camera Calibrator tag, it's a lot better, but still off:

What am I doing wrong?

Scene attached. Thanks in advance.

Hi,
you have not converted the scene to c4doctane.

Please try with this version:

Instead of c4d background, I have used a c4doctane Environment texture node in Visible mode, with projection sets to "Simple pos. to UV", and an UV Transform of -1 in Z Scale axis:

And for the object, I have used an Octane material with an ImageTexture node with projects set to "Simple pos. to UV", note the material tag must be set to UVW Mapping:

ciao,

Awesome Beppe, that seems to have solved my problem completely. Many thanks.
