[Nel] 3DSMax question : lightmaps parameters

[phlam]

Hi,
I have few questions about lightmaps parameters in 3DSMax

As far as I understand, here is the simplest process to get lightmaps on 
a mesh in the Object Viewer :
. Assign a NeL material to the mesh and set its Shader type to 
'LightMap', select a lightmap texture channel 2.
. Assign an UVW map modifier to the mesh, with the following parameters 
: Box mapping,  mapping channel #2
. Create a light (omni or spotlight), set its Color, Multiplier, Cast 
shadow, Far Attenuation ('start' value / 'end' value / 'use' checkbox)
. Check the Utilities / NeL Export / Options : 'Export lighting' and 
'Shadow' checkboxes
. If you select the mesh(es) and push Utilities / NeL Export / View the 
Scene, you should get a nice rendering in the Object Viewer.



Now, here are my questions :

. How can I have soft shadows ? All I can get is sharp raytraced-like 
shadows, even if the 'Light method' parameter is set to 'Soft Shadow' in 
the Options

. The NeL material(s) that has/have the 'Lightmap' shader type must have 
a Diffuse bitmap (NeL Textures rollout) or the lightmaps won't be calculated

. 'Lighting' node properties ?
 . Lumel size multiplier is a per object param. for the lightmap 
definition, that seems to be ok
 . Does the soft shadow radius work ?
 . What does 'Soft shadow cone length' mean ?

For a light
 . what is the difference between 'Realtime light' and 'Realtime Sun 
light' ?
 . what is the difference between 'Realtime light' and 'Animated 
dynamic light' ?
 . what is the meaning of the Lightmap Name ? Changing it doesn't 
change the generated lightmap filename


Thanks in advance
