I have just extracted this multipatch from LIDAR data and am now looking to apply a realistic mesh texture to it (I already have the mesh file and everything, file type of "3D Object"). Any help?
There is a Multipatch Texture tool in the ArcGIS Pro editing tools which lets you apply colours or image texture files to faces of your multipatch.
Apply textures to a multipatch or 3D object
I was looking more to creating an integrated mesh scene layer.
