Caveats

  • repeats is not only used to set the number of repeats but the sign of the individual components is also used to set the "Flip" attribute.
  • offsets and rotation_in_radians are limited to positive values only, unlike PRIM_TEXTURE and GLTF Overrides. To convert a negative offset to positive, add 1, and to convert a negative rotation to positive, add TWO_PI.
  • To clear the normal map parameters from the face (and possibly remove the material), set texture to NULL_KEY (the other parameters must be supplied in this case but will be ignored).
  • Note that whenever any face in a linkset contains a material (i.e. has a non-default PRIM_NORMAL, PRIM_SPECULAR, or PRIM_ALPHA_MODE), the linkset will use the new accounting system.
  • In the default texture mapping tg_type the texture repeats units are in texture repeats per face. In the planar texture mapping mode the texture repeats units are in texture repeats per half meter. This is in contrast to the in-world editing tool, in which the planar texture scaling units are repeats per meter.
