Nurbs texture stretch problem

[vyder]

hey guys..this has been plauing me for quite some time. i tried looking for some info on this before i posted, but no luck .

here is my dilemma.

i am modelling a sniper rifle for a modelling competition. now the handle of the sniper rifle is quite ergonomic/organic. i build the handle using a nurbs cylinder. of course i had to adjust isoparms for the creation of this handle. so the distance between the isoparms is not consistent. this of course leads to texture stretching.

so the next step i tried was to rebuild the surface so that it would create even isoparms. once the handle was rebuilt, i applied the texture to the handle, and the same texture stretching occurs.

i then tried converting the original handle to polygons and applied the texture...same thing. is there any way for me to apply the texture correctly? i thought the rebuild function would even out the texture uv's.

the last resort is using the polygon texturing tools to texture the handle. however i really dont want to go that route because the texture on the handle is a crosshatched grip, and to try and line that up is going to be pure hell .

Have you tried Fix texture wrap?
You can find the function on the Texture Map section of the Attribute Editor.
Just mark the check box and the effect will appear with software rendering.
I hope it would help you.

so u mean that rebuilding the surface does not help this?

is this the only way to correct this problem of texture placement?

Fot mapping texture correctly, you need to make isoparms at even intervals perfectly.
I think you can do it with 'rebuild surface', but you would enlarge number of isoparm too much unavailingly so that keep the shape of model.

'Fix texture wrap' is not only way to correct.
The other way is just using projection mapping then convert to file teXture if you like.

hey...ok, when i rebuild the surface..the isoparms are spaced evenly. however when i apply the texture..it is still stretching it. is there a way to reset the uv's when u rebuild a surface? its like the rebuilt surface is keeping the same uvs as the original.

did you perhaps turn fix wrap on and rebuild then test... now you should have unchekked the fix map.

Anyway the rebuilt surface will tell you where you have some streching problem areas you might need to fix theese.

you are offcourse aware that its impssible to get anything 2d wrapped on 3d for most shapes without any streching! Spehere being a perfect example of this. wich has caused a lot of pain for mapmakers over the centuries-
