Hi ClockworkOcean,
That can happen when rdLODtools canât find any textures in the meshes materials.
You can still create a billboard from it though - when you create the billboard, tick the âBake Lightingâ option - that will then use the original materials while rendering.
The âBake Lightingâ option uses the lighting you are using in the Mesh Editors âPreview Sceneâ - it is best if you turn the âDirectional Light Intensityâ down to 0, set the âCubeMapâ to Null and make sure the âSky Lightingâ is enabled, bright white and set to about 2.0.
If youâre creating a static scene with static lighting - you can bake the lighting in by using the âDirectional Lightâ in the Preview Scene, and altering the SkyLight color can create some interesting results too.
Remember to set them back after creating the BillboardâŚ
