Hello!
I tried to find an answer in google, but failed. I created a material with different maps, but i can’t make it look bump, because i don’t know where to apply a bump map(a grey node which is not connected). I tried to use bump offset as it was offered in unreal wiki, but it did not help…
By bump map I assume you are talking about a gray-scale height-map type of texture.
You could send your bump map through a “BumpOffset” node and use the output from it as UV input in all your texture samples.
This is the official example.
[Using Bump Offset][1]
Instead of using BumpOffset better known as Parrallax mapping you could simply convert your bump map into a normal map and use it as a regular normal map.
You could also use Displacement mapping that actually moves the vertices and is therefore the most expensive of these 3 types.
