Is there a quick way to check whether a 2nd UV channel exists?
I often import a mesh into UE4 Editor without making the second UV, in order to check if the scale of the mesh is right quickly.Only when it is right, I make the second UV for lighting. Over time,I forgot which mesh I have made the second UV for and which mesh I haven't,so I usually have a trouble —— After building lighting,UE4 Editor notice me the wrong lighting UV.
As we all know,building lighting will spend much time, so I think we need a button to check the lighting UV,and let it ready for all meshes.
Hi LinZhihao -
A quick way to look for what you are asking is to change the view mode in the editor to Lightmap Density. This setting will allow you to not only see what meshes have not been unwrapped but also if your unwraps need to be adjusted across multiple meshes and a color coded chart of the density of each lightmap unwrap in relation to each other.
