Multi-texture OBJ

[panicbuttonvfx]

This post pointed me in the right direction (I was setting the texture coordinate values to -1 instead of 1.1):

Translucent texture for texture coordinates outside [0,1]

Assigning values above 1 in the texture coordinates where you don’t have textures with setting repeat on the vtkTexture to False should do the trick. Here is an example using PyVista to show what this would look like: from pyvista import examples texture = examples.download_puppy_texture() texture.SetRepeat(False) mesh = examples.load_random_hills() mesh.texture_map_to_plane(inplace=True) # Now turn off a region of the texture mapping idx = mesh.points[:,0] > 5 mesh.t_coords[idx] = [1.1, 1.1…
