I’m attempting to use the WorldAlignedTexture node with a texture using nearest neighbor filtering, but the result is blurred. Help would be appreciated.

What is the resolution of the texture? If it is really low it sometimes gets blurred.
Yeah, It’s intentionally a low res texture (128x128) which is why I’m using nearest neighbor filtering. The texture is only blurred when used with the worldalignedtexture node.
Oh I don’t know much about textures but it may be worth scaling the resolution and giving that a shot.
Can we see a picture of your material network and the material preview?
Just a guess: maybe it is a mipmap scaling the resolution down?
Thanks for the reply. I’ll check that out and get back to you.
Same thing with no mipmaps
Yeah sure!
I think the problem is in the WorldAlign Function. I put my custom world aligned texture through it and it became blurred, but was crisp using my own uvs.
It’s quite funny, I just tried to use the World Aligned Texture and was upset about how textures were filtered.
so I made a material that did the same thing and maintained nearest neighbor filtering. Cheers.
Thanks so much for this! Any way it could work with normals?
edit: this also only seems to work on one axis
I made an improvement to the node set up, The first was a quick and dirty solution, texture were mirrored on certain sides. This new set up fixes all that. It’s still not perfect but if you need unfiltered textures it works like a charm, I hope that the ue4 team could make a version that preserves set filtering at some point, but they got better thing to worry about I suppose.
The solution actually are much simpler. All you need to do is to create a copy of worldalignedtexture function and change the following values in it: Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.
Now just use this function and it will give you sharp lorwres textures 
Works for all axis, just like the original one
Oh, and don’t forget to set texture filtering to nearest: Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.

Thank you, you’re a lifesaver
Here is the definitive solution:
double click the worldAlignedTexture material function node, then change the sampler source on the texture samples within it to be “use texture asset”.

This was the correct answer for me, thank you!
