I imported this as an .fbx file cuz .obj doesn’t hold colour values, but it is coming as an entirely different color. How do I fix this?
First, we need to know If you made some changes in the Base Color in Blender. I can see that there’s a red line in the sword meaning that you touched a part in Blender which I believe it’s Texture Painting.
To solve this problem, you need to remove the Material (make sure to see If it’s removed by looking as Material Preview) and see If it’s now working normal + giving the same color that gives for parts.
You could import it as different meshes and color them in studio individually.
You could import a texture and place it onto the sword. I’d have no clue though.
