How to apply a material to a hollow cylinder?

[Ivan3z]

I am trying to apply a material to a hollow cylinder in UE5.

When I apply materials to this cylinder using Blender or Substance Painter I have not this problem.

However when I try to apply any of the materials that I can find in the “StarterContent” folder the materials are not applied correctly.

Here are some examples (grass, marble and water)

Different materials and always the same problem.

These are the seams that my cylinder has. So I think it’s not a seam problem.

How can I fix this problem?

Thank you so much!!

Could you show us a picture of your UV map?

Hi:

Yes, your suspicions were correct, that was the problem. For some reason it had a wrong UV map.

I’ve fixed it and now the texture looks much better.

But now I really have a problem with the seams…

Thank you very much for your help

Now you would decide how to use the mesh:

1. Do you want the player/user to see the whole mesh?
2. Do you want the player/user to see only a part of the mesh?
3. Should you use a seamless texture?
4. Can you use a texture that covers the seam (e.g. wood)?

I’m sorry for my late to answer you. I had some problems this last days and it was not possible to visit the forum.

1-Do you want the player/user to see the whole mesh?
Yes, this was my main idea.

2-Do you want the player/user to see only a part of the mesh?
This was my secondary idea (a desperate idea). I was thinking to hide the seam underground. But i prefer do not that if is possible.

3.-Should you use a seamless texture?
I thing so. But unfortunately i tryed using severals methods i saw in tutorals and none works for me. Also i tried to looking for a method into the official documentation and i found nothing by the moment.

4-Can you use a texture that covers the seam (e.g. wood)?
That Is not the idea, i would like to use a dynamic water texture for the entire cylinder if it is possibe because It really looks very cool. (I attach the material code below… It is a very simple version of water material).

Do you think it is possible to get a seamless effect modifing this material?

I really want thank you so much for you help!! it is very appreciated!!
