The problem is that the image is not properly mapped on the sphere, there’s a big distortion.
Here’s the graph :
Here’s the result :
I believe I need to convert my UV coordinates into an equirectangular projection, I thought the UVtoLongLat function would do the job, but it doesn’t seem so, or there’s more to do with it, I don’t know.
Do you have any suggestions please?
