How should i set up a texture to use a bump offset correctly, i’ve made one in blender but it refuses to import into ue4 and i’m unsure how to fix it, any help would be appreciated on either front either learning how to just do it in unreal or getting blender to import correctly. Thanks in advance 
Hey there
What kind of file are you exporting from blender? and is there an error message when you try to import it in UE?
There’s no error message and I’m trying to import a material, I’m using a bump node on an image texture but when I import it is only a plain white material
Ah okay, the problem is that blender materials can not just be exported to unreal directly, it works with very simple ones, but in general i would advise you to export the textures (maybe bake them if needed) and then import the textures in unreal. There you can recreate the material using the unreal material system.
This is how you would set it using bump offset.
I’ve tried using it before to no effect unfortunately, completely possible I messed something up though i.e not connecting something right, however can you give me run down on how I should do the materials as it seems there are multiple different one I would need to make?
Hmm what do you mean you need multiple different ones? In general you make 1 material in unreal engine for every material you had in blender. First you bake and export the textures from blender (for example: albedo, metallic, roughness, specular, normal) and then you import them again in unreal (maybe you already have the relevant files, if you don’t make the texture procedurally in blender and you don’t have to bake them). You then either make a new material in unreal or use an existing one (depending on model import settings it creates them for you) and then you just drag the textures you imported into the material editor and hook them up to the material outputs.
Oh I’ve never baked a texture before so I was mistaken

You don’t have to bake them, if you are using textures from outside of blender. Only if you are making changes to them (for example color correction or smth) or if you are making them from scratch in blender.
if your material setup looks something like this, you can just use the textures you have in the image node.
For baking i would highly recommend this addon: GitHub - danielenger/Principled-Baker: Blender Add-on: Bake PBR textures with a few clicks
it makes the process a lot faster and easier…
Hope that helps
