Edit parameters for multiple meshes at once. Unify lightmap resolutions

Hi, Tim.

I’m sorry but that’s not what I ment. I’ll try to clarify my question =)

1. For example you import lots of separate meshes (no instances) and they all have wrong lightmap channel. So you have to go ahead and set the correct channel one by one instead of selecting all of the needed meshes and changing it once so the value is set for all selected meshes. And it’s not just about lightmap channel. For instance in Unity you can do exactly that - edit values for multiple objects at once. I was asking if there is same functionality in UE4 because I didn’t find it.

2. By unifiyng ligthmap resolution I ment setting the same pixel density for multiple objects (you can see it in the Lightmap density viewport mode). What you proposed will still keep the difference in lightmaps density which is there by default and you still have to adjust it one by one. Again, in Unity you have a uniform lightmap density by default which you can adjust manually on a per object basis. What I was asking was is it possible to unify lightmaps resolution in UE4 so the pixel density is the same across multiple meshes?

Hope that helps to clarify my question. Thanks.

1. With the meshes that are being imported do you already have a separate lightmap channel setup (Seems so from what I read but just want to make sure)? I’ve not personally noticed any issues with importing meshes with lightmaps that doesn’t automatically set the LM channel to anything other than 1. I’m not aware of any functionality to change that particular parameter across multiple different meshes since this is set in the meshes own mesh editor/viewer.

2. Ah gotcha! Wasn’t thinking initially about the texel density. This is not something that is possible currently with the editor.
