Context:
I bought this animal pack that I want to use inside of Twinmotion and maybe Sketchup. Thus I look for ways to export the .fbx file with textures. I find this tutorial on the matter which requires the use of blender. No worries, I'll follow all the steps.
But whereas he instantly gets a result while adding the textures (the viewport is updated automatically), I get nothing. I add the color file in both TGA and PNG versions and neither changes anything: my cow mesh is still metallic grey.
Here are some usefull screenshots of my blender workspace and also the texture files that I exported from Unreal Engine along with the mesh.
All the textures can be accessed via this Ufile.io link.
I'm thankfull for any tips anyone might have on this issue, I honestly did not imagine the usage of a pre-existing 3D cow would prove so complicated...
