Problem Semi Transparent mesh?

[Scruce]

I'm making a EVA mesh for Alexei Leonov's EVA, everything went fine up until viewing the mesh in Orbiter.

As you can see; the mesh looks fine in Wings3D (the mesh has textures built in):

But, after exporting to Orbiter, it looks like this:

The mesh was made and textured in Sketchup. Then it was exported to .3ds and opened by Wings3D, before being exported to Orbiter.

:sos:​

I suspect that some of your normals need to be flipped. In other words, what we're "seeing" is the invisible backside of your triangles.

Very, very cool otherwise - :thumbup:

What material/texture do you have on the stuff that's invisible?

Normal colours that were defined in Sketchup, nothing that required a .dds texture so there is not a .ds texture.

If you use Mesh Wizard (avail. on OH), you can select the mesh groups and flip visible sides. I'd bet a dollar that's the problem here. In looking at the picture, it really looks like what the textures would look like if seen concavely instead of wrapped around the outside.

I'll try that, thanks n0mad23.

What does it look like if you use the smooth-shaded view in Wings? It's possible that it made the material entirely transparent when it got imported to Wings. The visor doesn't look like it has backwards normals, and if that was the problem, you can just fix that in Wings--you don't need Mesh Wizard for that.

How would I do this?

 

[n0mad23]

On the bottom left side of MW's window, the group list is shown. If you highlight a group, it will be highlighted in the mesh view as well.

Choose the groups you wish to flip, and go to "Edit." Select "Flip Visible Side." When the sub-menu pops up, select from the "objects to flip" drop down menu, "Selected groups" then apply. You'll be prompted to generate normals. Do so from the same menu you're working from, and again choose "selected groups" from the available drop down menu.

You don't need to use mesh wizard. In wings you can select a body and choose invert and it'll flip the normals. It doesn't look like that's the problem, though...

Would you like to see the .msh file? If it helps..

Assuming you're using my Wings exporter, I actually wouldn't mind seeing the .wings file so I can rule out problems with the exporter.

Also, I've totally been looking at the wrong part of the image. I see now what people are talking about, and yes it definitely looks like it's inverted normals.

It's a large file, PM me your E-Mail address and I'll give you the (.wings) file.

Hey, that looks like the model done by Max Grueter. He did some really nice space related models in Sketchup. :thumbup:

Yep, I contacted him and he said it was alright to use it.

To keep it original, I edited it a bit, (changing some of the mesh and adding an untethered option as well (For free EVA's)).

I also am planning to add grapple point functionality for objects like a toolbox and work kit which are of my own design.

Orbiter can only use one sided faces. My guess is you are importing a model with double faces and Orbiter is changing them to single faces. The model was probably done one side only first then, mirrored.

Wings3d doesn't support double-sided faces (at least, not properly)--there may be some extra geometry that can get cleaned up, though.
