Without any question whatever, you are definitely not using UVW Unwrap correctly... Shocked

When in the UVW Unwrap Editor, you should NOT be adjusting individual vertex points. The only thing you should be doing there is adjusting entire sets of vertices for their position on the template.

Except for any stray edges, I'm just using the Freeform modifier to adjust the entire

Select the Polys I want to map, put in a "UVW map" modifier, select "Mapping: Face" there, then put in "UVW Unwrap", load the bitmap in the editor, "Normal map" (left/right) the polys to get rid of that garbled mess, fix any loose edges and freeform all the polys/vertices/edges (as one big selection) on the texture.

I don't know what went wrong with the rudder though. It's basically symmetrical (in terms of polys) and still gives me two differently "distorted" groups of polygons, which are awfully hard to fit perfectly.



- Edit: The non-fitting squares are due to the texture. This is just a test texture to see if two sides of a symmetrical object are mapped well (perfect fit), NOT to check the whole model!

- Edit²: Never mind the rudder. Simply mirrored one mapped side and moved the freshly mirrored map to its new place. Perfect seams now.

Fixed rudder with one uniform map.

Looking better.  What I do is (re)attach the rudder, doors, etc. to the fuselage, UVW Map/UnWrap/Edit the mesh...

...then Select by Element the rudder, doors, etc. and Detach to their original names...

Then, and only then do I animate them...  Cool

Thanks, you had me scared there a bit! Shocked  Cheesy

That attaching/reattaching thing is darn clever, this might save me a lot of work when mapping the wings (ailerons, flaps, spoilerons, speed brakes...). Thanks for the hint!


By the way: Can I leave some invisible parts of the mesh unmapped/untextured? Or is FSX going to complain about this?

Well, if they are truly "invisible," why have them at all? OTOH, if there's a chance they might be seen from some angle, then they should have a texture assignment.

The exporter will b*tch and moan about untextured polygons.  The best thing is to Map & Texture every stinking polygon...

Hint: one thing you can do is give every polygon that you don't want to "paint in detail" a unique MatID number such as 99. You can then Select all polys with a MatID of 99 (Select by Material ID), add a single UVW Map, a UVW Unwrap modifier, and then use the UVW Editor to scale/place all the unwrapped mesh to one corner of your assigned texture sheet where you've placed a 20x20 pixel block of color, such as "aviation green primer" or such...  Grin

Thanks for the "attach - deattach" hint, Bill!

I redid the fuselage and all doors yesterday (but forgot the rudder...but well, looked quite good anyways) and it worked like a charm! Well, except for destroying preexisting animations, of course. But thanks to backups, the keys could be restored (almost) a jiffy. Smiley

The way I've found to preserve animations/axis of rotation when I need to map or remap is to select the part, detach ALL the polygons and then attach the polygons to the fuselage or whatever I'm mapping.  After mapping, select the polys and then detach as as some object, then select the original part using the "Select by Name" window.  Reattach the polys and voila!  You have preserved both the animations as well as the rotational axis.

That technique does work quite well for re-mapping... Thanks for mentioning in here as I'm sure it will be useful in the future.  Cool

Some impressive work there Björn, have been long awaiting a model of a Do328 for some time.  Please let me know if you need any last minute images of the bird (real life) - I certainly have a fair few !

Haven't spent a single second on the model ever since.

Lacking the motivation to go on at the moment.
