PV 5.12 reports errors on opening wavefront .OBJ file which previous versions did not
On trying to open Wavefront object .OBJ files which V5.11.x opened without complaint, V5.12.0 reports multiple errors. "Unexpected data at end of line in .OBJ file L.60" to L.25468 These OBJ files have the weight at the end of the v,x,y,z co-ord but line 60 is not the first such line, nor is 25468 the last. The same errors and line numbers occur across multiple .OBJ files which include a weight. .OBJ files exported from a previous version of PV and which do not contain a weight, import without error so I assume that the support for the weight has been dropped. Although not sure why it is not reporting errors from line 6 onwards.
Attached a small .OBJ file and a snip from the .obj format doc. The .OBJ files were created from dxfs by John Burkardt's ivread fortran code which I have modified to increase the 3D array sizes significantly. DXF's only render as wireframes in PV hence the need to convert to .obj or .stl to have them render as solids.
