Apply image to only a portion of a smoothed mesh face

[matthewBirckbichler]

I am trying to apply new imagery to the geolocated terrain mesh programmatically.

I have an array of faces I want to apply the image to, but I want that array to act like a single face (like how the paint bucket tool would treat a mesh) and not just apply the material to each individual face.

Is there any way to actually import high resolution image?

@jniles You can project a texture from an imported image directly down onto terrain in SketchUp. With your dem terrain already in SketchUp, import your image and scale it to the correct size. You will want to have the terrain smoothed with the Soften/Smooth Edges feature so that the terrain is considered one surface. Elevate the imported image over the terrain and position it in the correct xy Explode the image… This will transform the image object into a surface with the image texture. ri…

I did read this post, however, as a ‘surface’ isnt really an object, I cant programmatically apply a material to it as a whole.

I cannot find an equivalent method to something like this:
surface.material = myMaterial

I cannot find an equivalent method to something like this:
surface.material = myMaterial

If the faces making up the mesh (that you wish to paint) are grouped and referenced as mesh_grp, …

mesh_grp.material = myMaterial

… would this work for you ?

this works to add the image, but when done this way, I dont seem to have any control over ‘centering’ the new image correctly. In other words, I am not getting a ‘projected’ result

Yea, ok. Texture mapping is done upon the face object(s). I am not really sure if a bunch of faces joined by softened edges are considered one big face or not.
