Black lines along photo tiles ...

Recommended Posts

Hi,I was discussing with someone else the black lines that appear along the photo tiles made as VTP2 custom polygons. At certain distances a narrow black line appears between the junction of 2 tiles and it disappears as we come closer. I think this is related to a "mip effect". If I run the ImageTool Help window there are some options that could be related (?) to this artifact. I suggested that the sides of the VTP polygon could be made larger so that adjacent photo tiles would intersect in a way to reduce those black borders. I use a SCASM macro (based on a macro by Dick) to generate the VTP polygons:; VTPm2Custom.scm macroVTPPoly( 2 4 0 ) VTPPointXY( [ %1 * 255 + 4080 ] [ %2 * 255 + 4080 ] ) VTPPointXY( [ %1 * 255 + 4335 ] [ %2 * 255 + 4080 ] ) VTPPointXY( [ %1 * 255 + 4335 ] [ %2 * 255 + 4335 ] ) VTPPointXY( [ %1 * 255 + 4080 ] [ %2 * 255 + 4335 ] )The idea was to change it to:; VTPm2Custom.scm macroVTPPoly( 2 4 0 ) VTPPointXY( [ %1 * 255 + 4079 ] [ %2 * 255 + 4079 ] ) VTPPointXY( [ %1 * 255 + 4336 ] [ %2 * 255 + 4079 ] ) VTPPointXY( [ %1 * 255 + 4336 ] [ %2 * 255 + 4336 ] ) VTPPointXY( [ %1 * 255 + 4079 ] [ %2 * 255 + 4336 ] )The question is that FS seems to crash when loading the BGL made with the modified macro. I see no reason why! Any tips?Regards, Luis
