Hi,

The following code behaves differently on a Indigo ELAN
and a 320VGX:

lmbind( ..wawawa )	/* switch lighting (lights,model,material) on */
lmcolor( LMC_AD );
  ..draw lighted stuff..
  .. c3f,n3f,v3f calls..

lmbind( LMODEL,0 );	/* disable lighting */
lmcolor( LMC_COLOR );	/* <- ?? */
  ..draw unlighted stuff..
  .. c3f,v3f calls..

Now, the unlighted stuff gets drawn depressingly black on a ELAN,
if lmcolor( LMC_COLOR ) is not used. 
The VGX behaviour is more similar to the man page: 
"lmcolor mode is significant only while lighting is on".

Bug, feature, or my bloody ignorance of something obvious ?

if( FAQ ) printf("our news server went offline for some weeks.sorry\n");

TIA

Peter
