Hello,
I’m having a problem when I build the light only. I got this error shown in the picture below. And I have a question regarding the foliage is there a problem if there are a lot of invalid foliage ?
thanks,
As for the Warning:
You need to have a single Lightmap for all LODs. UE doesn’t support unique Lightmaps for LODs.
As for Swarm Failing:
Try to restart Swarm. If you’re using a custom Branch, try to rebuild UnrealLightmass.
Sorry but I am a beginner with the UE4 could you explain how to have a single Light map and hot to rebuild UnrealLightmass ?
thank you,
Your Foliage Mesh consits of multiple meshes, depending on it’s distance (called Level of Detail,LOD)
Less Detailed Meshes seem to have a different UV Layout. Try to adjust the UVs of your LOD Mesh to the Layout of your Original Detailed mesh (Use Blender, 3Ds Max or any other tool for this)
If you are using an official Branch of UE (ie you downloaded the Engine via the Launcher) I don’t have a solution for your problem.
Maybe your firewall is blocking Swarm Agent. Make sure it is allowed in your Firewall settings.
Thank you all for your responses.
what if I could not build the lighting! can I package my game and have the executable file ?
^You can package your game without built lighting. It will use Dynamic lighting for each unbuilt object then.
This can be a heavy hit on performance.
Look at this thread:
maybe it helps.
