Trying to get a material on an object in hexagon and an artist I am not, anyone have a suggestion on how to get one on there? I have an .obj, but the “unfold” option gives me a blank picture. so I can’t paint it that way.

Unfold uv maps the model, which is necessary so that applications will know how to wrap an image around it. Once you have it uv mapped you need to create or assign a new, blank image, and paint into that. I don’t use Hexagon so I can’;t be more precise than that.

One needs to apply a texture to paint on.

Geekatplay is a Website that has over 100 Hexagon video tutorials.  It shows everything from modeling to UV’s to texturing and painting.

Well worth the time to study and review.

Since Hex does not render, I usually make shading domians in Hex but export and do shader or texture mapping in other program such as Carrara and/or uvmapper.

The example above and geekatplay has tutorials and that would be the least expensive.  3d-coat has an excellent painting ability but its not free.  There is a personal edition that supports up to 2k maps and the full version.

The free version of Blacksmith does excellent 3D painting - auto-generates UV maps, but they are atlas, so can’t be used as a template for future texture changes.  The texture resolution is limited on the free version, but good enough for most uses.

Ok, I’ve tried all these with no success. I’ve managed to finally start getting an image on the object by randomly creating one, but it is repeating and I don’t want it to repeat. Is there some way to stop that?

Yes there is, where/how depends on the program you are using.  It should have a co-ordinate setting (X,Y,Z plus offset in the X,Y,Z) which you adjust; normally to stop/reduce the repeating you need to lower the setting.  Which in effect enlarges the texture to fit your object, with the offset controls to position it in the right place.  It can get a bit fiddly but practice makes perfect.  smile

Not sure i’m repeating Red’s advice in another form:)

In the materials panel, where you set the resolution for the texture.  The higher the resolution, the more repeats you get.  256 X 256 gives me a single picture on each side of a cube, 512 X 512 gives me four per side.

There may be a relationship between those settings and the picture you’re using as a brush - haven’t checked

Closest I can get for it being even remotely legible is to use Planar UV and that sort of works, except…well as follows

That’s what I thought you might mean. A few posts up I mentioned about assigning areas to separate Shading Domains. That’s why.

The other way would be to check which areas are where on the flattened uvmap. One can make temporary Shading domains to move sections around and then assign them all to one if one is all that is required once the areas are not overlapping.

Yes it’ll work better that way.

It can help to think of ‘sewing’. We are “3d”, our clothing is “3d” ... but the patterns to make the clothing are “2d”. Where one puts the seams in RL [real life] translates over to the 2d uvmap for the 3d mesh very nicely.
