title: Blending two textures in a triangle poly
body: <p>I made a triangle in LIBGDX 3D using the modelbuilder.part and        meshPartBuilder.triangle(VertexInfo1, VertexInfo2, VertexInfo3);</p>
  <p>i apply this       meshPartBuilder.setUVRange(regions[z][x]); and it sets the texture region i want.</p>
  <p>but how do i set for each vertex to have a seperate texture and have them blended ?</p>
  <p>By the way this is for a 3D terrain.</p>
