HI Folks - apologies for being a nuisance yet again.
I am working with A7 in c-script.
I have a curved tunnel made in mdl (only way I can get smooth curves) with a wdl floor block. Both textured the same.
A group of blue crystals give illumination to the scene - dotted along the tunnel floor.
I then use pale blue light over the crystals to throw a splash of light on the floor and the tunnel walls.
PROBLEM - the floor picks up the light just fine, but the mdl walls do not !
I can't find anything about lighting mdl items in the manual or the forum. I have tried using the 'properties' box, but I can't light up an mdl item with a light!
How do you do this?
Hopefully, David

Anything other than static WED blocks does not support static lighting. You'd have to emulate that with dynamic lights (entity.lightrange) or sprite and texture work.
