-It is possible to very precisely locate a branch or leaf off of a photogrammetry mesh using [[target_generator|Target generators]]. ​ The general approach is to add a Target generator as a child of the mesh, use it to pinpoint a location/​orientation on the mesh, then add any child you desire as the child of the Target. ​ The children of the target will use the pinpointed locations and orienations ​as their starting point.+It is possible to very precisely locate a branch or leaf off of a photogrammetry mesh using [[target_generator|Target generators]]. ​ The general approach is to add a Target generator as a child of the mesh, use it to pinpoint a location/​orientation on the mesh, then add any child you desire as the child of the Target. ​ The children of the target will use the pinpointed locations and orientations ​as their starting point.

-When using targets to place welded branches off of photogrammetry meshes beware of uv island seam crossings. ​ Make sure the branch is located entirely within a single ​uv island to ensure no errors in the weld region. ​ The pic below shows a branch with a weld error both in the standard render mode and the texture coordinate seam render mode.+When using targets to place welded branches off of photogrammetry meshes beware of UV island seam crossings. ​ Make sure the branch is located entirely within a single ​UV island to ensure no errors in the weld region. ​ The pic below shows a branch with a welding ​error both in the standard render mode and the texture coordinate seam render mode.
