Weird black lines on a white texture

[Prolivion]

I modeled and hand textured an orca in Blender, but when I imported it to Roblox Studio, there were these weird lines on the white parts


When you zoom into it, the lines disappear, but the farther you go the blacker the lines get and it’s very noticeable from afar.
Just to clarify: These lines don’t show in Blender
Here’s how it looks like in blender

This is the first time something like this has happened, and I have no idea how to fix it

I believe that this is the outlines, so you can try setting part.Material to SmoothPlastic and all of the sides to SmoothNoOutline. If this doesn’t work, try smoothing the areas where those edges appear and reimport the mesh.

Try making/enable it "DoubleSided"? Maybe texture causing this.

I’ve had this same issue, make sure your texture extends past the uv boarders. When it’s too close there will be artifacting meaning when you get further away it starts counting parts outside the uv boarder. I usually bleed my texture out
