only one shadow map enabled with fromLightSource=false caused error

[flyingdq]

I usually want to use shadow map to do some postprocessing effects, and i use only one shadow map enabled which set fromLightSource to false.

so ShadowMap.createDerivedCommands will create nothing about the receive commands.
But in OIT.js, it shows below:

for (j = 0; j < length; ++j) {
command = commands[j];
command = defined(command.derivedCommands.logDepth) ? command.derivedCommands.logDepth.command : command;
derivedCommand = (shadowsEnabled && command.receiveShadows) ? command.derivedCommands.oit.shadows.translucentCommand : command.derivedCommands.oit.translucentCommand;
executeFunction(derivedCommand, scene, context, passState, debugFramebuffer);
}

it will cause error:
TypeError: Cannot read property 'translucentCommand' of undefined
since command.derivedCommands.oit.shadows is undefined

missing lightShadowMapsEnabled flag while excute the commands?

@lilleyse any ideas here?
