Max SDK C++ Create Skylight

[no.name]

How do you create a skylight in 3DS Max SDK?

The Skylight object is not exposed as a class in the SDK, but you can create an instance in a scene from its class ID:

INode* maxLightsDemoUtility::createSkyLight(){

Interface *ip = GetCOREInterface();

TimeValue tv(0);

// Light

INode *nodeLight;

GenLight* lightObjLight = (GenLight*) CreateInstance(LIGHT_CLASS_ID,Class_ID(0x7bf61478, 0x522e4705));

// show the gizmo

lightObjLight->Enable(true);

// add to scene

nodeLight = ip->CreateObjectNode(lightObjLight);

nodeLight->SetName(_T("MySkyLight")); // light naming

return nodeLight;

}

You can get the Class ID of a class in MaxScript using ShowClass(), or from an object in a scene using $obj.ClassID():

showClass "Skylight"
Skylight : light {7bf61478,522e4705}

Hope that helps.
