Tessellation height texture issues

[luffyfuffy]

Hi guys,

I was practicing with tessellation and faced the following issue. 

I'm pretty sure I'm doing something wrong but have no idea where to look. 

When I put materials/textures from Art Samples on the plane node, everything is fine.

However, when I'm trying to do the same with Free Stock Textures, issues start to emerge.

With Brick Wall texture https://www.texturecan.com/details/250/ goes fine:

 

For Red Bricks Texture https://www.texturecan.com/details/147/ I've faced the issue with tessellation render, it looks like something is wrong with height texture. However, changing UV mapping down to 0.4 0.4 seemed to fix the issue:

 

With the next Wood Triangular Wall Texture https://www.texturecan.com/details/507/ same issue, but UV mapping didn't help:

 

I tried to find any issues with height textures, but didn't find any issues with them.

Try to use plane with bigger amount of initial segments, 16 should be OK:

Yes, you're right. Everything works fine.

Is there any dependency/correlation chart/table between texture resolution and surface segments number?

Not really, you just need to find the best spot for exact material / texture. 1 segment is too low, but anything higher should behave better.
