View Full Version : UV Mapping with endomorphs - please help!

I really hope someone can help because I'm just about to top myself with frustration :help:

Okay, so I have this object (see below) that I want to texture. Because of its' shape neither planar nor cylindrical UV mapping works at all. Nor do any of LWs other non-uv texture options.

So I tried this:

1) Make an endomorph of the object
2) Unwelding the points and flattening out the mesh
3) Created new Planar UV texture of the endomorph now that it's flattened
4) Export .eps file into PS and create my texture
5) Apply texture which at this point, fits perfectly with no stretching
6) Merge points back together.

However if I go back to the "base" object (ie not the morph), the texture map is horribly stretched as it would have been if I hadn't bothered with steps 1-6.

So what, if anything, am I doing wrong? Am I trying to do the impossible here? I know the obvious answer might be to use Deep Paint or Zbrush but right now it's not an option for me to buy either of them so I need to find a work around within LW.

Thanks for any help :)

Apply textures, fits perfectly with no stretching? What do you mean? You would have to have all your points in your mesh at the exact points that they would need to be on your texture if you were to stretch your texture to wrap to your object (sorry, don't know how else to say that one). You didn't have any steps of serious tweaking to your map so all I can assume is that your UV map doesn't technically match your texture. And it won't if you just make a basic flat UV without lots of tweaking to match it to your existing texture.

Robin Wood has some excellent tutorials which demonstrate how to map using endomorphs.

Choose "UV Mapping" from the list on the left.

You have to use UV maps if you want to do it that way. To get a usuable UV image, just select the UV map in the Vmap panel and export to EPS, or google UV imaginator for a plugin to export them.

Thanks for the link:) I'll spend the next few hours following the tuts on his site.

One thing to check and I don't know if this will apply here, but in modeler, if you start with a straight shape, create a UV map and then apply a morph to that shape so lets say make a tube into an s shape - an old technique - and then look at it in the modeler preview, you would not see the result. It will be distorted. But if you load it up into layout and apply the morph it will look correct. Just wonder if this would apply to mapping UVs from a morph and then looking at the base object. You might want to try and load it into layoput and see.

Oops!! I did the dice tutorial yesterday which was very well explained.

Surrealist I did what you suggested but it still came out wrong although since following the tut mentioned above, I now realise I didn't get rid of the endomorph - well I didn't do a few steps correctly actually.

Hopefully by the time I go through the other tuts I will actually know what I'm doing :)

Thanks for the replies/suggestions guys, much appreciated.

Good. yeah as a realut of this thread, I'm going to do some of her tuts as well.:)
