Lightning Channels were something Unreal 3 used. The method it used had lots of options but wasn’t really good performance wise (in my opinion). It would let you seperate lightning information to channels so you could toggle them between.
This can not be done in Unreal 4 as Mr Hobson said.
Change your texture to unlit and set you base color to go to the emissive(so its not totally black). You should stop receiving shadows now. I know this is an old question but I was also looking to do this and this and I thought I should post it here for anyone else looking to do this
Is this possible now? There’s plenty of reasons why you may not want an object to receive shadows… distant super low res LOD’s (such as mountains as poly strips, or a entire city as a ‘super lod’) can look really bad when casting shadows as the shadow projection aliasing kicks in.
But - you still want the objects to be lit… you want it to react to sun light and ambient light… so the emissive approach isn’t good here.
Is there any update on this?
It would be great to be able to specify if you want certain object to not receive shadows from another specific one.
Lightning channels are only 3 and sometimes its a bit of an overkill when you need to put only one actor in the entire channel.
