ok been playing with this today and I consider it a must have already...

jeff hammond · 19 Nov 2009, 19:30

khai - you have to sell it man!
let's see some pictures of what you've come up with

Khai · 19 Nov 2009, 19:34

lol sorry

the bugbears I've had is UVmapping and OBJ export..and this solves both in one shot.. I'm kinda excited lol

Yeah...let's see some pictures of what you guys can do with this!

Thanks, Dale. Will try this with Modo.

Dale, tested with 3ds Max and it worked flawlessly on this teardrop shape using the Unwrap UVW modifier. Thanks for the plugin. It will fix a lot of headaches!!

One of the issues is that once a UV is imported, it does not "stick" to the geometry it was assigned to. For example if I did not like this brick and wanted to replace it with another material, the UV's become scrambled again. Also when I try to undo after importing the UV's, I get a SU crash.

Great! Another app to add to the list! Thanks for testing

Yeah, I hate that SketchUp does not keep UVs when switching materials. I'll look into that crash, too. Thanks!

Can you write the UV data in an attribute? And using it from there... It would increase the size of the file, I think... for each face to write separate UV. But it can be a way.

Yes, you can. I use that method in SkIndigo but I have not yet added the feature to UVTools.

When using Oscar's UV mapping and tried to render with Maxwellrender I noticed that it exported a bitmap for each face and made a copy of used material for each exported bitmap. So, I had situations when I had 1000 materials just for one object
This is strange... I was eexpecting that the bitmap to be folded around object.

I have NOT yet tested this plugin on a Mac but I suspect that it will work fine.

nah, it doesn't even appear in the context menu.. (well, the spherical & cylindrical still do but that's it)

edit-
haha.. hold on a minute.. i guess i'm in the wrong place because it is in the plugins menu..

[cut me some slack though..it's friday night and i'm messing around with wine & UV mapping)

Khai · 21 Nov 2009, 05:15

should one drink and draw?

jeff hammond · 21 Nov 2009, 05:55

ha.. sure - just don't look at the drawings in the morning and everything will be okay.

the plugin works on mac just fine (tested using argile)
i don't think that's the right app for me but that's beside the point..

Thankyou Whaat for this fantastic plugin. I tried it with UVLayout. It failed to work with Sketchup 6 and had me feeling gutted that I had spent a few hours learning uvlayout for no reason. Then tried it with Sketchup 7 and it worked thankfully!

Yes, the uv's will become scrambled momentarily when you change to a completely different material, but go back to the uvtools in the plugins menu and re-import your external uv settings onto the newly scrambled material and it will revert back to the pervious mapping settings you had but with the new material.

So here is a quick example of the plugin in action:

In su7 before:

With the plugin applied using uvlayout:

I have run into perhaps a bug though.. while I set up the uv mapping correctly in uvlayout - I got an error message when importing into sketchup. It told me import successful but 1 face failed.. This is the result:

Before:

After (notice the scrambling along the center)

I have one more question which isn't related to the plugin but something I have experienced myself (with my basic uvmapping skills) and is something I also noticed in Whaat's videos. When I split open my mesh to flatten it, when it reassembles the joining seam never lines up correctly... any simple suggestions to combat this?? i'm thinking there must be some sort of weld function i'm missing inside the uvprogram. Here's an illustration anyway:

Are you sure it only works in SU7? If so, that's very strange.

It looks like from your image that more than one face failed. This 'bug' seems to be caused from SketchUp not 'liking' the UVs that are generated from the external application. I'm not sure how fixable it is...

Here's an illustration anyway:

Seams are (by definition) discontinuities in the UV coordinates. I think the only way to avoid seams is to use spherical and cylindrical mapping. I don't have a ton of experience with UV software. There might be a weld-type function somewhere that will align the UVs along both edges of a seam.

vidy · 24 Nov 2009, 22:31

yes whaat, it failed in sketch up 6.. could it be fixed?

Chris Fullmer · 24 Nov 2009, 22:41

Dale did you use the "true" flag in "modelstart_operation "UV Mapper", true"? That will crash a plugin in su6.

Just a thought,

Chris

Yep, that was it! Oops! New version available that works now with SU6.

numerobis · 1 Dec 2009, 00:58

Thank You very much!!! It's working great! Unbelievable... proper mapping in sketchup!... this is so cool!
i've tested it with UVLayout - i have some scaling problems when i apply the same material to multiple unwrapped objects, but i think this can be adjusted in uvlayout... i don't know how at the moment but i'll find it out...

vidy · 1 Dec 2009, 14:50

Thanks Whaat, its working now.. its great to have a function of 3dsmax Unwrap UVW inside sketchup
