Help with a 3D model
 

Hi everyone!
In those days i'm trying to rework an old model. I've, btw, a problem.

I've imported the reworked main hull obj. All work fine!
I've modified a little some UVmap, and imported new hull obj, CTD.
I've reloaded the previous obj, and again it work fine.
I've tried a little to move some points, and imported this new hull obj, CTD.
Again, the original reworked main hull is fine, but suddently, i'm not able to make small adjustment to the obj. This without increasing vertex, faces, poly or angles number (i've tried also to delete some faces \ poly in order to test this, again, CTD.

Import with Pack3D or 3Ditor is ok, problems appears only when i try to use the ship in SH3, so this can be related with SH3 engine? :/\\!!:/\\!!:/\\!!:/\\!!

If you can, please, help me!

Best regards,
Vd

Did you get an error while unwrapping in Wings3d or whatever modeling program you use? I have found that, if you get a "Cannot Calculate Normal for Chart" error while skinning in Wings3d, the model will have certain problem faces you have to delete. If you try to run SH3 with the model it will either appear distorted or crash. I have been able to detect "problem faces/polygons" by applying the skin in Wings3d before I import in S3ditor. If a polygon in a model appears to be untextured, badly textured, or distorted even after the whole model is skinned, there's a good chance it is a "problem polygon".

I had this problem with my U-139 submarine at the tip of the stern (this problem seems to occur often with cylindrical or spherical bodies). I resolved it by deleting the bad polygon and re-modeling+reskinning the stern.

For texture mapping (and etc.) it is better to use Autodesk Softimage 2015 SP2...
or Softimage XSI Mod Tool.

Thanks iambecomelife and Anvart, and everyone help me via PM.
Problem solved! Following iambecomelife's suggestion, i try to split the hull's model in parts, and import them one by one, step by step.
CTD appears when i added a lateral gun's platform.

Now everithing works fine!
Thanks, this community is (and still) great :up:
