    Help, it seems i need to use Matrix, but I didnt understand how to do it, after reading manual.

    The problem is: I have a figure - let say 9 vertices, I want that the texture center was attached to any vertice. Attached image.

      The easiest way to achieve that is
      1) keep Shape's 0 coordinate on shapes center
      2) position texture using Matrix, where tx and ty are basically x and y coordinates, all other should be unity matrix, which means it should look like:
      local m = Matrix.new(1,0,0,1,x,y)

      Great ! It attaches left upper corner of texture, so if we want place the center - we should use

      x = xCoord - textureWidth / 2
      y = yCoord - textureHeight / 2

      Thanks a lot, now my shadows are incredible ^^ !
