The 8K metal rust textures seamless, with the necessary set of maps for blender and Unreal Engine 5 at an affordable price.

It is possible to use this texture without a normal map, but using a Displacement map, or using it together as shown in the image below.

The texture of the brick is orange with elements of efflorescence (whitewash), with the necessary maps for blender and UA5 at an affordable price, of good quality with a resolution of 8K (8192 x 8192 px). 

Recommendation: 

It is possible to use a texture without a normal map. Instead of the usual method, the Image Texture + node is used Displasement as shown in the image below.

Also, do not forget to set the parameters in the materials by changing "Bump Only" to "Displacement and Bump" in Settings -> Surface as shown in the image below. These settings will give the effect of cement indentation, which will give a realistic appearance to the wall of your object. Remember that before using this method, the Subdivision Surface modifier must be applied to the 3D model. With a low number of polygons, this effect will not be observed.
