UV Mapping (Lamp)

#1

OK. One of my biggest problems is UV Mapping. I usually use UV Mapper Pro, but I want to start using nothing but Modo, for modelin and UV Mapping.
I finished my Lamp modeling, and now I am trying to UV Map it. I UV Mapped most of the areas, BUT, I cant get for the heck of me the center bars area to map. I tried unwrap, cylindrical, planes, nothing comes out properly.

Perhaps one of you can show me what I can/should do with that area?
Here is the model itself. I would like to learn to do the UV Mapping, so if anyone can tell me what I have to do for it to work, please I would appreciate it very much.

Modo Model

I appreciate your help on this, and Thank You…

I would recommend UV-peeler, one of the Modo UV-tools. First you may have to separate the arch-shape from rest of the model, that’s what I did anyway. Then select a line of edges where you want the seam to be. Then hit UV-peeler and click into you UV-space. Voila! The part is mapped cleanly.

I sent you a private message with link to your model where I tested the above thing.

Welding the part back to the main lamp did bring some issues in the UV-space, though. This is because there is a part not yet UV-mapped: ring of polys, both upper and lower surface of the part that joins the archs to the upper section. Mapping them removed the issue(check the file), but they take lots of UV-space now. You might want to re-map the top-part of the lamp with these polys included in order to save your UV-space.

Another option to UV-peeler would, possibly, be morphing each arch to a straighter shape, UV-mapping, and morphing back to original arch-shape. UV-peeler seems like far less work.

I hope this helped. Happy UV’ing!

Thank you very much. I got to look at your version, and really got me going on the Peeler UV Mapping. That thing comes in very handy.
I UV Mapped it and all, and came out OK, I will post the model soon as I get it painted.

But to my surprise is that the Painting part is really bothering the heck out of me.
After I UV Mapped it, I started to paint the model. 90% of the time when I paint in Modo, it crashes, and thus I have to keep saving the image every change i make, which is no big deal, BUT:
Once I go back into the program, I load the model, then I load the Image (the one I started to paint), and dragged it over the model in the 3D Window. It shows up, then I go into Paint Layout, and try to paint. I cant. Everytime I try to paint it tells me, No image to Paint, please choose a image. I just cant get it, and I have to start all over again to paint the model. If it crashes again, which is quite often, I gotta start over everytime.
Now I did the UV Split Screen, and I CAN PAINT in the UV Window after I dropped the image over the model, but I CANNOT PAINT IN THE 3D WINDOW ON THE MODEL ITSELF, once the program crashed that is. The only way I can paint over the model in 3D window is if I start a new Image Map for the model, loosing all I did before the crash.
Is this a bug, or what can I do? Or do I load the painted image into the model the wrong way? Or do I take the wrong steps?

I tried this on 4 different machines, I thought it was the video, but cant be on 4 machines, can it?
Got ATi mid range card, Nvidia Mid Range, Nvidia VERY HIGH END Card, and a PCI-E ATI high end. On all of them the program crashes when I try to paint, NOT ALL THE TIME, but quite often.

Again thank you for your help, really helped a lot. Loving this program more and more, lol.

Glad to read Peeler solved your problem :slight_smile:

 "No image to paint"-thing
 So you have a model with an UV-map and a bitmap on.  On any of the menu-windows open up menu called CLIPS.  It is under "Data Lists" if you have to add it to your layout.  Now you see what textures are in use.  Next to the texture there is an arrow.  Click it to open up more details.  Now you can select the actual bitmap from below.  Then paint.
 
 I had the No image to paint-issue before, and had to go to material editor to select the bitmap there before I could paint.  But then I found the Clips-menu.  I have recently painted a low-poly character that uses two bitmaps - I switch between them in Clips.
 
 Crashing?
  I don't have Modo crashing while painting.  That is strange.  I don't think I can help here.  But I can say my way to set up the texture was like this:
 I made the preliminary texture in Photoshop and saved it.
 in Shader Tree: add layer  >  bitmap  >  selected my texture 
 in Shader Tree: moved the bitmap above my material so it shows in 3D view.
 Saved my scene.

Selected my texture and proceeded to painting.

Your testing should prove that the crash isn’t hardware related. For the record I have a high-end PCI-E ATI card and no crashing.

You could first search and, if not finding anything helpful, then ask about the crashing issue on Luxology forums.  [http://forums.luxology.com/discussion/](http://forums.luxology.com/discussion/)

Thankx again Sleepyghost, very much appreciate it. I will take your advice and go thru the Shader Tree and see what happens. Hopefully it will work, works for U, so its gotta work, lol.

It crashes, but as I said, not all the time, so I guess I will deal with it like that.

Thank you very much again for taking the time, very much appreciate it.

The peeler worked really great, and now I can UV Map Pipes/Wires that are bend with no issues with the peeler, very useful. THANK YOU…

Thank You…

Thank you again. It worked as you said it would. I used the Shader Tree and applied the texture and works. Still it crashes every so often, so not sure what that is all about, but at least now I can paint over the model with no issues, lol.

Thankx again for your help.

As you can see from the pic attached, thats the error I get.

Error in Front2.dll
Appname:Modo.exe

And I have to restart over the image, but I can at least now paint on the model itself.

This happens no matter which Layout I am in. I can be in Paint Layout, or Modeling Layout, or split 3D Layout, it does it in all of them.

Well, wanted to show the error itself, just in case many someone has had this before.

Thank you…

Hi cornelp

I would recommend filing a bug report and if possible attaching a link to the mesh at Luxology’s official site.

If you log into your account, and click on the “Welcome User Name” you will have the option to submit a bug.

The devs might even get back to you with a solution to the problem.

One of the first things to try is making sure your video card drivers are the most up to date ver of them.

Hi Cornelp

Sorry, took my time replying. Good to read you got the painting working - bad that it keeps crashing.

I second what Phil Lawson wrote. Though if you are still an evaluation user you do not have the option to report a bug. At least I didn’t find it. The option, I understand, is there only for the licence owners.

#10

Aahhh good thinking - I’ve always had modo so wasnt sure how that option effects evaluation users.
