Create texture from ortho images

[olihar]

I have been creating 3D mesh from DSM images I have and this is working great. I as well have orthographic images of the same area and I am trying to find a way to texture the 3D model using the RGB ortho images.

I can’t seem to find a way to do this.

I am doing this to create low res 3D models to have as backdrops for higher resolution models. I am creating from drones.

Is it not possible to project ortho image onto 3D mesh? It would just be projecting directly down on the z-axis so it should not be too difficult.

Only thing I have found so far is the satellite image workflow.
