Topic: Porting problem...

[Centurus]

Na, it's cool.  I didn't know you gotta relocate them each time.  Now that I know, I think I'll be ok.  I'm reinstalling both MAX 5 and MAX 9 again right now.  Just in case.

[Centurus]

Ok, now for some reason the Split Edges script won't work.

[FoaS_XC]

Can you be a bit more specific?

[Centurus]

Attached is the error I get when trying to run it.

[FoaS_XC]

Hang on a sec, let me look into my script.

[FoaS_XC]

I can't seem to find the cause of the problem, but I'm coding up an alternative as we speak.

better yet, I found another script that did work with your model.

Code: [Select]

theEP = selection[1].baseobject --get the base object of the selected object

edgeCount
edgeSelArray = #()

k = 1
for i = 1 to edgeCount do
if openEdgesBitArray[i] == false then
(
edgeSelArray[k] = i
k = k + 1
)

HardEdgesArray = #()

sg_bin_array = #{}

sg_bin2_array = #{}

--edgeSelArray
--edgeSelArray.count

ost = deci - (deciT as integer * 2)
deci = deciT as integer
s = (ost as integer) as string + s
)
while (deci as integer) != 0
dec2bin = s
)
)

deci = deciT as integer
s = (ost as integer) as string + s
)
while (deci as integer) != 0
dec2bin = s
)
)

Just create a new script, copy this into it, and run it.

BE AWARE. on the front of your nacelles, in those little square cutouts, you have some duplicate verts.

[Centurus]

Odd, I had spent over 2 hours on the nacelle cutouts to make sure there were no duplicate verts.  I'll double check, but I'm positive there aren't duplicate verts.

[FoaS_XC]

There should only be 6 edges here, yet I have 12 selected. It is like that on each cutout. If you scale the model to be pretty big, reset the transform, then do a really small weld with all verts selected, thats a pretty sure way to get rid of any duplicate verts, but there is always the potential for a screwup, naturally.

[Centurus]

Must not have saved it the last time.  I fixed it now.

[Centurus]

I went over the entire mesh again, double checking all verts.  As far as I can tell, no duplicates.  However, even that new script isn't working.  Keeps generating the same kind of errors, but on different lines.  Why, I don't know.

Also, I can't seem to open the BFF file in MAX 5.

[Centurus]

This is what I get when I try and run the script in MAX 5.

[Centurus]

Ok, got it imported, but no dice.  The model is still splitting itself apart at the seems, making duplicate verts.  For example, on the rim of the saucer, where there would normally only be 2 verts, there are now 4.

I don't know why this is happening.

[Centurus]

Ok, unless I'm a unique case, I think I might have figured it out.  I decided to look at a few models made by other people, namely WZ and FoaS, cause theirs were the most readily available on my computer, and I discovered something.

While concentrating on one edge of the saucer of the ships from both respective modelers, I'm noticing duplicate verts as well, in the same manner as my Demphir, which by the way, the smoothing is intact now in SFC format.

I'm thinking maybe this is how the models are supposed to be.

[FoaS_XC]

Don't use grouping what so ever. Just don't use it. I imagine this is why you are getting the error in BFF as well as the split smoothing scripts. Better to attach a model into a single editable poly. I don't know why they still implement it in max, but it screws with everything. Re-export the scene using BFF After you've ungrouped the mesh. It should reimport now.

Split mesh is duplicating verts on edges that are non-smoothed. This is because if you were to use a totally welded model, SFC will smooth the entire thing and ignore your smoothing groups.

I realized grouping was causing a few problems, so in my last few attempts I've ungrouped the components.  However, even without the groups, and the entire mesh joined as a single object, I still get the script errors.
