what want map 'ang.png' file on t-shirts this

what want

thank answer radio, tried way not want do.

give name material , map

you've applied same 'ang.png' texture child meshes. think need conditional in traverse function apply texture part of mesh needs texture.

the mtl should have applied name material when first loaded. example, here pretending material name "torso". exporter original 3d editor have given other name. in case, should able query name in conditional:

          object.traverse(function(child) {              if (child instanceof three.mesh) {                           if(child.material != undefined){                     if(child.material.name=="torso"){                       child.material.map = texture;                     }                  }              }           });
