[Plugin] Import OBJ with Materials v2.1 20131118

rombout

I got one more question about this version. On one of my mac it was working fine, sadly that one broke down. Now im back to my old macbook mid 2010. When i try the latest version the same model i tried earlier shows the quads half flipped faces. I had an altered version on the other mac, mac didnt seem to have an proper backup of that one.

When i check the main plugin info, it says there was an update "feature proof";
2.2 20131228 Future proofed.
Yet in the addon when added it doesnt state that. There its says this as last update;
2.1 20131118 Import of OBJ files using a -ve counter for f vertices within
sub-groups fixed. View now refreshes with each group completion.

Don't worry about the version text in the RB file itself.
It's no longer updated.
The Rev notes in the PluginStore page are correct.

The v2.2 was stated as 'future proofed'.
That was back when SketchUp was about to migrate to some new API methods and a newer Ruby version in v2014.
Just prior to that version's release, major developers were given some confidential prior knowledge, to let them get their scripts ready for those changes, but they couldn't expand much on what had been changed 'under-the-hood' without revealing what was impending in the SketchUp release... hence 'future proofed'...

It is an old script and has not been changed in about five and a half years !
However, it should still work on older and of course the newer SketchUp versions.

Install the latest version [v2.2] from the PluginStore...

Okay, thanks for answering. I found it weird that the same models now seems to have flipped quades (normals inside-out). I tried the OBJ importer from quad tools, never new this had one as well. Seems much faster and imported perfect. Just like OBJ importer did on my other machine with the exact same model. So i really dont understand why on this machine with the same plugin it acts different.

I dont think mesh color is supported, only textures. Try using the scale or import option and use bigger scale. That sometimes seems to fix the uvs. You can also try the OBJ import with quad tools

PS i did a quick check with Blender. These cubes dont have a proper UV map. The texture is super wide as well.

EDIT
here's is that same scene and model, now it imports just fine

Hello

If i try to import a .obj-file, that is made with blender, it does not get it´s textures.

In blender tihs model has got 192 vertices and 225 faces.

Is it too complex for this plugin?

TIG

I'm no buying it !

It doesn't look complex at all...

So does it come with both OBJ and MTL files ?
Is the MTL file properly named in the OBJ file, i.e. relative to it ?

Is there a subfolder of material files ?
In the MTL file is the path to that material subfolder properly named, i.e. relative to it.

Show us a screenshot of your folder set up etc...
And perhaps an extract from the start of the OBJ and MTL files showing file/folder details...

Drachenbauer

It has .obj and .mtl and there is a folder with the material-texture.
the texture includes all parts of the model, that it looks a bit like a papercraft-template.

In the first try it appeared white, and in all followinf tries it had my default outside-color (my default material is outside yellow, inside white).

TIG

Sadly you did not answer my entire question.

Also note that there are several options regarding the importation - so ensure you choose the 'with textures' option...

I export a blender mesh with vertex painting texture, and use this but nothing shows up at all. Its blank. The blender export is both .obj and .mtl files but Ill double check their validity through other software also just in case its an export issue, but any thoughts? Not even mesh shows up Thank you for your time and patience!

USING: SU8FREE(or as they say pre 2017) windows 10 64 bit and noting the mesh is over 300K+ lines

TIG

If you have the Ruby Console open when trying this are there any error messages ?
Have you tried a much simpler Blender OBJ with textures ? How'd that do ??

This plugin spoils the entire mesh while importing

TIG

Why not try something newer, like Universal Importer ?
