A model I downloaded from Sketchup and converted to OBJ using Blender, imported into Poser 11. Most of it looks good, but the front window has dark streaks.

Looks the same in Firefly or Superfly, and normals forward and remove hide backfacing polys doesn't change anything.

It looks like this if I turn smooth polys on:

It's all materials, no textures. Even the text was done by making separate material zones.

Reversed normals in the model?

where the windows have long, skinny tris, that's what's doing it. the tris that are close to equilateral usually aren't affected, but ones like the windows often have problems in poser

Long thin triangles?

Thanks, it is the long, skinny triangles. Increasing the subdivision levels insane amounts makes it look a lot better.

I think I'll just make the windows black.

If I liked the model enough, I'd retopo it and kill all the tris. It may take a while but eventually, you end up with a leaner model that loads faster, takes up less RAM and renders better.

I fucking hate triangulated models with a passion.

That's probably beyond my capabilities. I used to do some simple modeling with Anim8or years ago, but haven't done anything recently. I opened Blender for the first time today just to convert this model! ?

Sketchup stuff always exports as tris. I only go there for what I need as a last resort. I spend more time fixing the topology than I do with the rest of the scene. I need to learn to model faster

I could fix it fairly easy enough for you.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.

Thanks, rokket, that's very kind of you. But if I understand the license correctly, that would be not be allowed. Modification of the model is permitted, but not redistribution.

Hmmm, ok.

have you tryed changing the smooth angle from 80 to 22.5.that works for me most times.

I did try that. It didn't have any effect this time, though you're right, it often helps.

You can play around with it in Meshlab (its for editing 3D triangular meshes and other mesh related things ) and try and clean it up a bit. other than that retopo as SamTherapy already mentioned.

Okay... I had to get the model to see it myself... I used SimLab CADVRter Free Trial I got the OBJ file & the MTL file and this is how it's supposed to look. The dark streaks are the windshield material cutting thru the cockpit shell/frame or the space between. Make the material called "Planetary" invisible. If you download the collada version you'll get the three JPEG files inside you're missing... the textures he covered the ship in... these textures are not reflections but they're made to give that impression.

I set the winshield to be transparent somewhat... and I removed the texture he was using it so now it's plain white and transparent no reflection... the image you see thru it is the cockpit frame, he textured that too the same as the windshield... so if you remove the windshield you have a shell underneath... whatever that is.

So underneath the windshield there's another material

What I converted to OBJ is the Sketchup 2020 download, not the Sketchup 2019 or 2017, or the Collada... he might've fixed the windshield sinking thru the shell in the latest version. The dark puddle you see in your last pic is the material called "Planetary" surfacing thru the shell.

Actually, I removed the textures from the model before I rendered. The dark streaks are just what Poser does with really long, skinny triangles. (And I know I didn't miss any, because I had to go through each material one by one, since they have uninformative names like 1, 2, 3...)

It's a pretty good model aside from that, and the crooked text on the port side. It looks like what's it supposed to look like (a custom shuttle from Star Trek, weird window frame and all).

You could still fix that in a 3D modeling app by deleting the edges that form triangles and making them quads. It's what I would have done.

If detriangulation is your aim, you could try Anthony Appleyard's detriang utility (Windows only though).

It's in freestuff here (although I couldn't get it to download), or on his site at the bottom of this page: http://www.aappleyard.com/3d/3d.htm

It's basic, but faster than using basic modelling functions to merge faces.

Can I get a link to the model?

Thanks. I have Wings 3D, Blender and 3DS Max...

Interesting. I'd never even heard of it, though I've downloaded a lot of Anthony's free stuff in my time. I managed to download it. It's getting late here and I have to be at work early tomorrow (actually in the office my one day a week on our new pandemic schedule), but I'll try playing around with it tomorrow night.

Rokket, it's not hard to find with that Google search. I didn't want to post a link because of Rosity's rules about linking to other sites.

I can't get it to open in any of those programs. I guess it's not meant to be.

I think Blender (and probably your other software) hasn't been updated to the 2020 version of Sketchup yet. I couldn't open the 2020 file, but the 2017 version of the file was fine.

I'll go back and get that, then. Thanks.
