I created an aircraft model in 3dsMax, then realized it was HUGE (about 30x too big) when I converted it through GMax to a .mdl file. So, I went back and scaled it down to a proper size, checking it with the Tape tool (and also making sure it was the proper metric units)... but now the Makemdl exporter seems to choke on a lot of the vertices, and gives these lines in the log file:

(Part Fuselage) Found colocated vertices within triangle
(-0.000390, 0.001196, 0.010703)
(-0.000205, 0.001137, 0.011634)
( 0.000139, 0.000920, 0.010716).
(Part Fuselage) Found colocated vertices within triangle
( 0.000139, 0.000920, 0.010716)
( 0.000207, 0.000876, 0.011552)
( 0.000424, 0.000000, 0.010915).
(Part Fuselage) Found colocated vertices within triangle
( 0.000207, 0.000876, 0.011552)
(-0.000205, 0.001137, 0.011634)
( 0.000158, 0.001186, 0.012134).

...etc. etc. many times (to make a log file of 400k!)

A friend of mine who is a programmer thinks it may be some kind of floating point interpolation prob with the large scaling difference, which has "confused" the exporter...

I tried using the Optimize modifier on the whole model, and also Weld Selected on vertex sub-objects, but this distorts the model and still has the colocated vertex errors (albeit fewer ones).

Is there any way to solve this prob w/out having to go back to Square One? (Sheesh... it was a lotta work!).

TIA, -Johno

Typically you should just need to weld vertices on just that part - fuselage, in this case -

Could it be that you have too large a weld threshold?

PteroKat, check your international settings in the control panel.
Don´t know how exactly it translates into english, I´ll try anyway.
Under "numbers" or so, set your decimal separator to a point rather than a comma, this should most likely cure the problem. This is for the case that it´s not a problem in your source file.

Well... I've messed around with various cranky exporters... Shockwave 3D, Plasma, Flash etc... this one beats 'em all...

Here's what I've accomplished so far in GMax/Makemdl, using my too-big 3dsMax model (after about a dozen different tries):

I'm starting to think it's not a vertex weld issue, but wholly due to scaling errors...

In 3dsMax I did a Group on all the aircraft parts (fuselage, wings, tail what-have-you, which all appear in the error log) and applied a Xform modifier... scaled it all down to 10%... then collapsed the Xform... then unGrouped and exported it to GMax. It was about 1/5th too small in there, so I scaled it UP to the right size... and hey, presto! ...an error log file ("colocated vertices") of only 5K! Ahh, maybe I can work with this... (I think??).

I won't go into all the see-saw scalings and error logs before that... it makes me dizzy just thinking about it... don't know what happened exactly, but somehow I got it pared down.

Lesson #1: Scale It Right The First Time, Bubs! (but hey, that WAS my first time... I didn't mean it, honest...)

etc. etc.

In the decimal/comma issue, Mathias... I assume you meant the Windows control panel? I understand that the US notatation is to use points for the decimals... but there are some other countries that use commas... the default in my box is points, near as I can tell.

Anyway, tanx for the responses, guys...

(think maybe I'm getting close, though).
