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

Fixed files

V2.2
I export my objects in OBJ format from MagicaVoxel a terrific Voxel prog! (free)
Reload works fine in Wings 3D (free)
No color inside SU or special result!
Glitch ? ...
Its the same if export the objects from Wings 3D result!

or that!

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

I was always trying to do this as well. Not sure you still need it. Couple months i got it to work. If you have the unix version you open Terminal and drop that file in there. Best thing to do is to make a folder on you desktop. It doesnt like space in file names therefor its best to do it there.

Then drop you xml model file also on there, now you see 2 file paths next to each other. Then simply hit enter/return, you could get a warning if you dont have proper java lib installed, click more info and download the java for OSX.

Then try again. The OBJ will be put in the folder where you dropped the xml model file from. It doesnt get a MLT file, so you would need to recreate the material though

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 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.

Not sure whats happening, but removed all other. put them back restart and now it seems to work again... weird stuff

Im baffled, i worked for a while and stopped again. I didnt put all my other ql plugins back and so i did. Then nothing happened again.

Now ive taken all out accept qlsketchup and still nothing is created??
Also thumb generator was working and that as well stopped now. I think ill do a restart orso.

Heavy models do take super long to save, is that due to jpg creation?

I got it working by changing the plist file

I went on for hours checking and googling stuff. drove me nuts. I even installed Xcode but got to the point where you need to add code which does all the work and look at the folders and files. I didnt know what todo there.

So i went on again looking in other files. Then i noticed that when i changed com.skethup to com.sketchup.skp it does work again.

This is the altered Plist i got.

So su18 supports finally thumb previews? thats about time

Does it also preview material icons now in material editor? I use thea and has own material library, yet it doesnt take the icon out of the material but shows a texture only

I did some more digging and found a method how you can see what quicklook can see or what is using it for that

skp isnt linked to anything as it seems. Could you have a look at i again perhaps
