Ortho facade - render bug ?

Hello, Please, I was able to render good orthophotos this morning. I tried to generate new model and now I am not able to obtain orthophotos. The result is shown on the right part. I tried to remove and put back the reconstruction region, move/rotate my model but still don’t know what happen. My texture model looks fine (see one part attached). Do you know if there is one parameters which is not correct ? Thank you !!

 

Edit : how can I had picture to this post ? 

Answered on Arena. To add images they need to be smaller as 2MB. You can also add print screens.

Yes, thank you.

Actually my issue was georeferenced problem.
I just choose project coordinate systeme : euclidean and that solve my problem.
