What to do with very small uv island?

Hi, I am not good with english so, i will ask directly. What to do with very small uv island?
For example, we have poligen loop, with only one pixel width. We have no place for any baking or texturing. What to do?

oglu

scale it up...

andy939

but chow  much i can scale it up?

oglu

until it does look good and you dont have mipmap errors...
and make sure its 100% straight...

If it's small and nigh on unnoticeable I'd sew it onto a larger shell just to not annoy me, it wouldn't affect shading that much anyway.

if you have a hard edge there and use normalmaps thats not a good idea Axis5..

Yeah in general, but meh, if it's less than a pixel it's probably low interest, I'd question the purpose of the geometry at that point.

but when i scale it up to get 3 pxel it become very big

show us the asset and uvs... ohterwise we cant really help...

If it doesn't matter, put it somewhere insignificant

If it will never even be seen, delete it

If it needs more resolution, scale it up

I dont want to show this model right now, but i have a lot parts like this:
https://naforum.zapodaj.net/b92547346ef8.png.html
and, they have 1 pixel width on uv or less, uv resolution is 1024x1024. I be able to see that geometry on 3d model, so i dot wat to remove them.
when i scale it up to get 3 pixel width it become very big, I need to scale it x2 or x3. and then some elements can be long for half my uv space, and when i scale it up in one direction the uv become stretch.
And should I laso scale up the island that is conect to this one on the 3d model?

Texture only 1 section of the pipe, then copy to make a longer pipe.

Yep, modular pieces will solve that problem.
