Any idea why the some pieces don’t show seams in POV-Ray but they do in MLCad? Sorry if this has been addressed elsewhere. I did search for it, but I didn’t find anything. (Newbie to all this.)


For example, this is the model as seen in MLCAD. (Notice the forklift has defined lines between the rails and the forklift platform.)


And this is the same model after being run through POV-Ray 3.6 (Notice there is no visible seam between the rails and the platform piece.)


Thanks for you help.

Just an update. I never really resolved the problem. But for now I am working around the problem by manually entering the .5 spacing that L3P would usually add between parts in POV-Ray.

(...) The problem is that L3P fails to recognize the two unofficial parts as parts. Try moving 3429.DAT and 3430.DAT to the PARTS folder. See also (URL) have already a long time ago updated L3P to scan a part's header for "Unofficial Part" but I'm (...) (18 years ago, 24-Sep-06, to lugnet.people.newbie, lugnet.cad.ray)
