Why is that ,while using the paint brush tool to paint an object, after painting some of the mesh suddenly the whole object gets covered in the selected colour? Its quite annoying as Im trying just to paint certain parts of an object. |

You can paint a face if you want.. or paint all the object if you want.. even you can remplace a specific color or material on a same object with a click..
Now im at work and i cant show you how.. but is no clue about painting an object..
Best Regards. |

if you are using the paint faces tool (the paintbrush not the paint roller) I can't see how this would happen, I tried and can't get it to do that. I know that if you select a bunch of faces then select the paint faces tool, it will paint all of the selected with current material, but you'd have to be in point edit mode and intentionally do that for it to happen. |

Have never heard of this either, not sure what the cause would be. Some screen grabs might be useful. Mainly it sounds like the Paint Over Existing roller was used instead of Paint Face, but can't see how that could go unnoticed, clicking on the different icon (accidental press of a hotkey?).
HTH!

That's what I think that happens. "Paint over exiting material" will replace all faces of the same material with the actual material in the material editor. |

Its just happened again and I was using the paint face tool. I was holding down the left mouse button and paint over the object when all of a sudden the whole object got painted. (?) |

OK, getting more odd behaviour! After setting up a UV plane for one side and then opening up the UV editor I found I had a whole window full of random lines. I had to use the little black arrows at the bottom of the UV editor to find the actual image I was looking for. After exporting it to Corel Paint and producing a quick test texture I found the texture had appeared on the OTHER side of the model. Going back to my UV editor I zoomed out to find endless tiles and my original uv map. See image. Whats happening to my TS, its going crazy. :s

"Random lines" are totally normal if you have not unwrapped your model. Have you selected the faces you want to edit before opening uv editor?
With the small arrows you can skip through the various textures you have painted on your model, so I guess you have not selected the right faces before.
The tiling you see is normal, in case you want the texture to repeat on your model. You can also set this in the material editor (u, v repeats), it's just the visual aspect of that setting. You don't see the tiling if you reset the editor's view, do you? (right click on the white square of the uv editor widget)
I don't think your tS is going crazy. It's rather something you have missed or you done wrong. |

BTW, I see your object has SDS turned on. I recommend you extract the final mesh before mapping and editing. I think that's what is causing all the strange behaviours.
To extract it, right click on the "add sds layer" icon, and click on the brownish icon. |

Sorry more questions!
I applied a PLANAR map to the right side of the bird and exported it to Corel Paint as a test. I quickly sketched some basic feather shapes onto it and saved it. After going back to TS I noticed that the texture actually appeared on the left hand side and had been rotated. Whats happening here? |

Also my exported images are screwing up. The first image on the right is the texture map, the image on the left is what I get when I 'send bitmap to external editor'.

This is all a bit bizarre. I uninstalled TS then reinstalled and now when I apply UV maps to each side Im finally getting the red, blue green and yellow maps showing up in the UV editor window unlike the black ones I was getting in the image above. The only problem now is Im still getting rogue triangles showing up
for no reason. What could be the cause?

I too have problems with the export bitmap functions. There always seems to be an offset that I can't fix. I use other programs for that. The rougue triangles could be triangles that are not mapped properly. Check your mesh for a triangle with white material (cos there's a white one in the editor).
It's normal that faces with just a plain color have the same color in the mapping editor. Don't know why they have been black before. Could be because they were textured. |

Once Ive saved the map and applied a texture on it how do I export that back onto the object?
When I open it up in an external editor the image map is the size of a thumbnail. This is all really baffling me. (??) |

I figured out why the saved texture map was soo small. It was because I had tex res set to 64x64!!! Im still left with one final problem though. The texture map keeps getting applied to one pologon of the object and not the whole object after Ive exported it, painted a texture and saved it. TS does'nt apply the texture as set up in the UV maps. Plus Im still getting a patchwork of the imported texture appearing in the UV editor window. See image.

Maybe I've been asking the wrong questions. I think all I need to know is how, once you have saved the UV maps, you use them to apply texture maps to the object. Ive just been opening them up in Corel Paint and drawing over them and then loading the object into TS again. Do I not need to load the UV/texture map into the material editor and paste the texture onto the object? |

When you UV mapped the object the first time in the editor, it is already UV'd.
I find the tS mapper confusing and is why I use UVMapper.
The only hitch is that you have to save the object in an OBJ file so it can be imported into UVMapper.
I'll try to put something together so you can see how I would UV a human. Nothing fancy just the basics. :) The advance texturing takes a bit more time so won't get into that. |

Many thanks. I'm sure I'll get it eventually its just Im getting very odd behaviour from my UV Editor. |

Many thanks for taking the time to produce your reply. The thing is I do know how to UV it just seems Im having trouble UVing the model Im working on. Maybe Im applying the wrong type of maps to it but Im just getting rather perculiar results once Ive produced a texture and gone back to TS. See my last image.
Maybe if I could send someone my model they could work it out. |

By exporting the uv-layout, you are NOT exporting the material. This function is only supposed to give you a guide to paint your texture, nothing more. You then have to load the painted texture into material editor, and paint your object with it. |

What I have noticed though is the exported UV layout never quite seems to match up to the actual UV layout once I load it back. Something seems to happen to it inbetween exporting it. It always just out of line.

The image underneath is the test exported UV map which I just quickly coloured and the top is the actual UV map. As you can see that don't line up. No matter how much I resize them they never match. Is this just a limitation in TS ie its not perfect? |

This happens to me as well and I don't know how to fix it. There are useres who don't experience this problem. I just use a different app for mapping. |

I have a hunch what the problem is. The same thing happens in UVMapper and PS if the zoom in PS is not 100% Maybe the problem is related to the size of the window open? Just a theory. |

The UV Mapping Editor window can't be resized so I guess it can't be that. |

In my case the uv export is always shrunk in V direction. The upper parts match, but there's an offset at the lower border of about 20% and I have to resize the export manually to make it match the uv's of the mesh. Anyway, I hope this doesn't happen anymore with 7.5. That happens if I paint the object directly with the exported bitmap as well , so no PS involved. |

Just like to say thanks to everyone for their assistance in helping me to understand all of this texturing business. I've finally got around to starting to texture my bird model. I've attached what Ive managed soo far.
