Hi everyone,

I was just recently trying to export a new model.  Import went just fine, but when I try to save as a .pof, several polygons on the wingtips disappear.  The_E requested that I post this issue in here, so here it is.  I'm using the PCS2.1 Alpha from July 18, 14:39:17.  Here's the file I was trying to convert.  http://filesmelt.com/dl/GefjonDAE.7z  The_E said this was definitely a problem with the pof exporter, so if there's anything more I can do to help, please let me know.

Have you tried the latest version?  That's probably the best place to start. 

[esarai]

Just did.  No dice.

Were they double polies? You would need some thickness to them or they might get merged.

[Vasudan Admiral]

Linky no worky.

I also had this happen to me.
Lost some polies on the left engine of the Daegon.

[pecenipicek]

could it be maybe because the shield mesh imported absurdly smallish?


wait. WHAT?

a lot of stuff is scaled down by at least 50% in the dae you linked us all to.

Alright, update time. 

I checked the source file, and the faces in question were not doubled over with anything.  I noticed that in the version on my computer, everything was the correct size upon import to PCS2, but when I handed it to The_E, he reported odd scaling differences.  I checked source again and found detail0 to have been scaled up by a factor of 2.48.  I applied scale and rotation for the mesh (aka set it to 1,1,1) and attempted to import again.  This time everything worked fine. 

While it seems as if support for objects that have non-unity scale factors has been added, I surmise that something is going wrong in that section, as unity factors do not create this problem.

Actually I've seen similar issues even with 2.03.  Now for the great part it only happens on Nvida video cards and not even all of them.  Have not seen the issue even once on an ATI card.

In working with the original DAE files from mjn's missiles, the Cyclops (tech and regular) is the one that seems to like dropping polies on me the most on final save to POF.

Even if I don't go through the trouble of smoothing and resizing. No double triangles. No mesh issues that I can discern with faces or vertexes having inversions. It'll just decide that it is going to give me a hole in the model.

[Droid803]

Yeah, saving to PMF or whatever is fine, its just the export to POF that decides to throw out random polies.

I was also having this issue, but I found a way to reliably fix it. I use 3ds Max, so I use OpenCollada to export to DAE. In its options there is a checkbox that says something about triangulation. I usually leave that checked. However on the few models I had that got random holes, simply unchecking that box on export solved the problem. It worked every single time. So I'm not sure exactly what is going on through all the conversions, but it seems to me that the export to POF gets real picky about its triangles.

I also noticed the holes I got in my models weren't hole polygones, but literally just a triangle. That's what led me to the solutions.

[chief1983]

Triangulation doesn't have to be done in advance of PCS2 right?  I thought it happened at some point automatically down the line.

[Droid803]

Thing is this doesn't happen on the older versions of PCS2, only the latest ones.

[Rga_Noris]

When working on the Hatty in Blender, this happened a few times. The way I fixed it was selecting everything and pressing control + T to triangulate BEFORE any exporting was done, leaving no triangulation up to any exporter or PCS2.

[pecenipicek]

most collada exporters triangulate on export.





the solution is pretty much what RgaNorris said, triangulate before export, and you should be good to go.

[esarai]

Alright, I'll do that.  I just noticed this supposedly 'clean' model actually has parts missing from the guns.  They were so small I missed them until just now. 

[Spicious]

As far as I can tell it's losing the really thin triangles. Scaling up by a factor of 100 keeps everything. I still don't know exactly where they're getting lost though.

[Talon 1024]

This problem is still happening on the newest builds of PCS2.  Here's an example of a model that is affected by this problem.  There are some polygons missing on the rear left engine.

I tried converting some of the triangles into quads, triangulating the model before export, scaling it up and back down again, but nothing I tried helped.

Try this. Try it with other things too and let me know what it breaks.
