Noob Question (UV Mapping)

Hello all i wasn’t sure what to name this post as i realise it’s not easy to describe this image.


Image from Aussiex.org - Author of paintwork - Peter Munnery.

I am making a bus, not this one but the Scania East Lancs (K230UB) Basically the shape of the bus is this. http://www.flickr.com/photos/nsf323alistair/6226134671/

And to make it so that other people can repaint the model as they wish, it needs to look like this, the template but i want to map it to my model in Blender but i’m trying to make a 2048x2048 image so that i can place the relevant sides to the sides of the model, for example, the entry and exit door side, the back and the front, also the headlamps and the wheel textures. So far i’ve managed to colour the bus with small .bmp images but it looks unprofessional.

How would i draw the image to suit the scale of the model and how do i know what scale the model is to be able to fit it to a 2048x2048 image in the UV image editor?

Sorry to sound confusing but i’ve been trying to work it out myself, this will save on loading time in the game.

Here is a photo of the model in question


Many Thanks!

I take it you only want to texture the outside of the bus, not the inside as well.

And you want to end up with a single 2048x2048 texture.

Well - create your image on blender’s image viewer. As the bus is basically a cube you might be able to cube-map the cube (enter edit mode - select all - U (unwrap menu) select Cube Map). If that doesn’t work - select the edges between the top, front, side etc and press CTRL-E and select Mark Seam, then press W and select Unwrap.

Or if you want to use the image above as a starting point, select all the faces on the side - make sure the view is flat on (looking directly at the surface you have selected - no perspective) and press W and select Project From View - Bounds and scale to the correct part of the image in the image viewer.

oh thank you. this really helps; but i will try the image above and use that as a base to see what happens, It is actually made up of Planes and cubes :wink: but i thank you all the same!

Also the interior i will need to texture as well but i’ll use this method, but if anyone has any suggestions on the interior please do reply.

Thank you!

start by selecting some faces that will be mapped to an existing part of the image texture. for instance, the side is one part of the texture, so select the faces of the model that belong to the side. it appears that the texture is made to scale, so ‘project from view’ is the unwrapping option you want to choose. make sure you are looking at it from side view in the 3D window. when the side of the bus is loaded onto the image, simply move and scale your coordinates until they match the part of the image that they belong to. repeat with other sections. remember when you’re doing the top, you’ll want to be in top down view in the 3D window, etc. hope this helps.

This is perfect thank you, i tried the project from view and even with the 2048x2048 i still was getting a few anomalies. It would be nice that in Project from View, i could save that image and export it into Photoshop and colour it accordingly, so i can have the frames of the bus but it doesn’t allow for such. I’ll do what i can, thank you again.
