Unwrap UVW problems

[newman]

First, if you're making a texture that has a seamless material with occasional splotches, then make sure that the seamless bit is really seamless. Also keep splotches away from the edges of the texture. Your model looks fairly complicated so you might want to unwrap bits of it separately, collapse, apply unwrap on the whole model and then make manual adjustments in the unwrap window - you may find weld and stitch controls to be useful.

thx your reply
in fact i really need to make some dirt on the edges
not only the splotch

3d paint is the way to go for texturing across UV seams. Do a search around here for advice about 3d paint programs, a couple are free.

Your never going to unwrap this thing properly by applying one cylindrical mapping. Your going to have to use different mapping types for different parts of your object. When you have the UV modifier select, highlight a group of faces and choose your mapping type. I usually start out with Flatten mapping (its not in the modifier column, it's in the UV Editor) and see what I can keep. If you like the results move them aside and deal with whats left.

Your model has parts that you will need to use relax dialog on. Also pack UV's is useful. I don't use it as a final method to pack my uv's but its a good start. pack uv's and relax dialog can also be found in the UV editor.

Oh and it will help a great deal to apply a checkerboard image to your model while you unwrap so you can see where any distortion is. Relax dialog will help fix that.

You could try going about it the opposite way; first create an UV map, then make the texture.. Take your model, apply unwrap, hit 'edit', go to polygon mode, under 'mapping' select flatten mapping, then under tools select 'render UVW template'. Select the desired resolution, render, save, then get this pic in photoshop, lock its layer, make a layer over it and draw on it. Having max opened to check what in the uv template is what can be helpful.
