Material seems off compared to SP

HaxLee

Hello guys, this is my first time using Unreal 4.

What I'm trying to do here is exporting my SP project to UE4, but I get this weird render from my viewport,
the material for one part just doesn't match with my final work.

The red highlighted part supposed to look like the rest of the ship. it also shares the same material as the green highlighted part,
the rest of the mesh that's sharing the same material turns out fine, but just the red part is acting weird.

This is what it looks like in my SP viewport:



I've tried rebuilding everything in UE, that includes the light, double checked with all the linked maps.
also checked the channels of the map, everything looks fine from there.

Still I have no idea where went wrong, any help is appreciated,
Thanks.

Make sure srgb is disabled on roughness, metallic, and ao texture, and is enabled on base color maps.

Double checked, yeah, everything is as you said. still getting the same outcome

Obscura

Can you show the texture settings of the roughness/metallic map, and the material?

HaxLee

Here are the settings for all respective maps that I'm using

Your masks texture is set to normal map compression instead of masks. The one that has the roughness and metallic in it.

Ahhhh I see. Thanks for the help!

EDIT: I noticed if I set the compression as Default, it's exactly the same as mask. Which mode would you advise to use?

uneducated guess, but you probably want the mask compression mode, or whichever one is for multi-channel packed maps (although Default always seems to work fine for me). They should have little tooltip descriptions if I remember correctly.

Just to make sure, you've got your red, blue and green channels linked up to the right inputs?

It isn't exactly the same with the default settings. By default, "default coompression" has srgb on. But if you switch from like masks, it will have the previous settings so it will be disabled. The difference is the sRGB which the masks shouldn't have but color maps should.

Once again thanks for the info
