Problem with Normal/Bump textures

When I place a normal texture onto my material, it renders out very weirdly. This issue only occurs with the normal maps, the diffuse works fine. This problem also occurs with all normal textures, so it could be something I’m doing wrong within UE4.

I’ve include a picture so you can see what’s happening.

Open up the normal map texture and make sure it’s compression is set to TC_Normalmap.

You have to make sure that your normal map is imported with normal map compression settings.

But to me it looks like the normal map is completely wrong, usually if it’s compressed wrong or something like that there’s at least some similarity to what you would be going for, but the normal map doesn’t look like anything at all. Are you sure you created the normal map correctly?

I’ve investigated it with my team, and it does seem to be an export issue with Blender. The normals aren’t perfect yet but they look a lot better than before. Also the compression was set to default but I am setting them to TC_Normalmap now as well, so that should help too.

I would add something to the name like _normal which UE4 will recognize and automatically apply the correct settings for it as a normal map.

“_normal”

did not know that.
guess _NRML will not be used by me anymore :stuck_out_tongue:

I also didn’t know that! I’ve been using _NM and setting the compression manually. Very tedious.

Now I know what to do!
