texturing a cube with seamless tile

daveso

I have been messing around with trying to skin a cube with a seamless tile ... see image. 
Note how the top does not match the sides. The sides seem to be seamless ..the top not. Is it possible to have the seamless carry over on all sides?

well it is but not using just any texture

rather a texture that is mapped to it

I have spherically mapped cubes to take 360 photos but even that not good you get distortion

however you can get a 360 image remapped to fit a box mapped cube beautifully

that is one way to do it, use a program for creating skyboxes like panorama tools

the other way is 3D painting

so like breaking down the cube flat ... and then applying the texture? as in UV mapping. And Carrara can do this?

not well no

a dedicated UV mapping program could but I would honestly not go the spherical route myself

rather convert the texture to a cubemap

I am trying to find something I can actually link thats noncommercial

dunno if that helps

I have an old qtvr program that does it I think no longer has a free version

Well, there's always procedural stuff like my shaders. ;)

if its a truely seamless texture another way is to simply flatmap each side of your cube to overlap the others

I had a quick go in my favourite UV mapper

I made one also using deformation on a sphere

so it;s really a sphere LOL

mmm the UV mapping seems to have changed on export

this is rather odd

You can also adjust the tiling - if you set Horizontal Tles to 3 and Vertical Tiles to 2 each face of the cube will have the complete map applied, which will then join seamlessly if it's set correctly (all edges match - some will match horizontal to horizontal adn vertical to vertical but not horizontal to vertical).

wow..thanks..yes... now, it's a square..why 3:2 ? i need to ponder this a bit

 yes, but then I wouldn;t learn what I have today ... I was messing with PSP and came up with what I've done so far... its not for anything but the little ping ping that goes on in my head 
what cool designs, whatever can i churn out?

I used to do renders in Bryce by placing the camera inside a sphere or cube .. and if you applied certain shaders/materials, some wild stuff would come out of it ... maybe I'm ovrerly bored or something

3 by 2 because that's the way the cube is mapped, two rows of three faces on the UV grid.

ah ... simple enough :) 

Thanks everyone for the help./

I really was over thinking it and I knew the DAZ studio primitive cube had a 3x2 UV layout too

thought this was a more complex issue with cubes in general and untiled textures
