A new Export Textures parameter has been added to the SEPVtrn.ini, SEECtoJT.ini, SE2VM.ini, and InsighXTtoJT.ini files that exports textures from Solid Edge parts to a .jt file. The default value for the parameter is 0, which does not export the textures. You can change the value to 1 to export the textures.
