Lighting error

Development Rendering

Hello guys,

i build a little scene with some modular mesh pieces. i sculpted a bit and set up some materials to my static objects. so not a big deal.

Now i wanted to place some “Sphere Reflection Captures”. I’ve only one little Point light and one Sphere Reflection Capture in my scene. I changed the Viewmode to Lit and used under the cateroy “Build” the “Build Lighting only”. After a while of compiling i get this error message:

“Performance Warning No importance volume found and the scene is so large that the automatically synthesized volume will not yield good results. Please add a tightly bounding lightmass importance volume to optimize your scene’s quality and lighting build times.”

I dont know what to do actually. Hope you guys can heko me.

Hi Mobpapst,

You’ll want to add a Lightmass Importance Volume to your scene for your playable area. This documentation will help you get started with Lightmass Volumes.

If you’re still having issues or have any other questions feel free to ask! :slight_smile:

Thanks mate, now it works :slight_smile:

But i have a short additional question. For a quick test i placed 3 “Sphere Reflection Captures” around one object. This object is standing on some tileable floor meshes. After building my light with the 3 “Sphere Reflection Captures” i got some material errors because of having same of multiple meshes.

Its because of:

  1. the 3 near placed “Sphere Reflection Captures” ?
  2. the multiple copied floor meshes?
  3. the small placed Lightmass Importance Volume cubecage?

i am also facing the same issue. When i build the light in my scene it throwing the object has wrapping uv’s"error.

Hi ued,
