The Lightmap Material
is used to import a Lightmap from 3DS Max that contains a pre-rendered lighting greyscale image used when static lighting and shadows are applicable in a scene.
Please see Import and Export Advise Board: topic: 3D Studio Max: How do I export a model?
, and also use the forum search for "lightmap" for additional information and user comments at the forum.Billboard Materials
let you import an image and apply to a plane that always faces the camera. It lets content be used with low rendering impact but is only suitable when continuous camera facing is not obvious for the scene, such as for photos or in video where not noticeable. For example, photos of people are often used. There are examples in the Lumion Library
- 2D People (high and low detail).
Please also search the forum for "billboard", that will find posts on billboards and how to prepare, there's some good step-by-step posts from users.
and is their any way to provide a cove light (rope light, indirect light) in the ceiling , cuz too many spot lights or omni lights are making the seen too slow and difficult to work with .
Other light shape types such as cove and rope are not provided in Lumion. The work-around is to have a light shape (mesh) that you can use with high Emissiveness
values that then glows. Then, add a few Spot or Omni lights to approximate the light caste on to other objects (sometimes these are not required, depends on the scene lighting needs).
Adding real-time IES lights to a scene does require a lot of performance from the PC. A couple of suggestions include:
1. place lights in to their own layer(s) and turn on/off in Build Mode as needed
2. follow the guidelines in SPOTLIGHT PROPERTIES LUMION 3: Tips, Tricks and Shortcuts
3. follow the guidelines in LUMION 3: How to reduce render times
