Creating / Manipulating UVs for new .objs?
Good morning Daz community,
I am trying to create an environment prop, and have no idea where to begin.
Geometry: That is relatively easy (I think). I can use Inventor or some other CAD package to make my geometry. (And then export it to Daz in cm scale.)
Importing into Daz and applying a material I can do. Some of the surfaces look good, but others are completely whack. (This is after I scaled my texture tiling to 0.01 in both U and V.)
With the default UV map Inventor generated, we can see that the texture does not apply 'correctly' to the item. (And indeed, the UV view in DS shows quite a mess...)
What is the "easiest" method of going about and fixing the textures on this .obj file, so I can use the item in Daz?

CADs often make horrible meshes when exported to .obj format. Could you show it in DAZ Studio in wire shaded mode?
That's a tricky shape, you are not going to avoid stretching and/or seams (imagine making a real version and think how the bricks would have to be placed to make the half-dome). Perhaps box map the main wall, then cylinder map the recess and possibly sphere map the haf-dome, then fiddle around to place maps in your image editor rather than try to just use a tile in DS.
Are there tutorials for how to do that? I have not read it deeply, but the reference section for Hexagon kinda sucks.
I don't have or use Hexagon, but I could grab some screens or do a quick video of the process in Blender if that would help?
Everything you do is helpful!
Anything helps! I haven't learned Hexagon, nor have I learned Blender yet. So I am on an equal footing with both :)
The mesh is too messy. You will have a nightmare trying to UV-map it. It's probably better to model it again in another 3D modeller.
Okay, have a look at this! You can download Blender for free here:

You may be thinking, looking at how long the video is, that I have an extremely poor grasp of the word "quick." You are not wrong.
Thank you SickleYield! Everything else is ready, now to watch the video and make the alcove look good.
(attached image obviosly is my attempt at doing things before the tutorial - texture discontinuites all over. Will come back and post the improved finished work later.)
(Deleted comment. I decided my thoughts wouldn't be particularly helpful at this juncture.)
The mesh wasn't as bad as I would have expected but all those triangles is what makes it hard to UV map (and the long skinny tris can often cause shading problems).
@srinity - I am curious. Are you intending to use this object in other 3D software? Or do you only need to apply surface/textures for Daz3D?
Have you tried using the geometry editor tool in DAZ3D? I am by no means an expert but when I import models to DAZ3D I use the this geometry editor tool to 'skin' them by assigning surface group properties. You can apply a surface property to any triangle or group of triangles, once you have done that you have options to customise how that surface is applied with as many variations that you could wish for.
It would seem to achieve what you appear to be asking, if I am understanding your initial question correctly.
