In Target Expression tag not able to enable camera dependent option. In below code, I m creating a Target Expression tag for a camera.TextureTag* Tag = static_cast<TextureTag*>(TestCamera->MakeTag(Ttargetexpression));
if (!Tag)
return false;Tag->SetParameter(TARGETEXPRESSIONTAG_LINK, TargetObj, DESCFLAGS_SET_0);
Tag->SetName("SetTarget");

As already mentioned in another thread of yours, you really shouldn't cast a Target expression tag into a Texture tag, rather treat it as a BaseTag.
The camera dependent option is part of the priority. PriorityData a custom data type (CUSTOMGUI_PRIORITY_DATA). So in order to modify this parameter the code looks for example like so:
GeData d; targetTag->GetParameter(EXPRESSION_PRIORITY, d, DESCFLAGS_GET_0); PriorityData* prio = static_cast<PriorityData*>(d.GetCustomDataType(CUSTOMGUI_PRIORITY_DATA)); prio->SetPriorityValue(PRIORITYVALUE_CAMERADEPENDENT, true); targetTag->SetParameter(EXPRESSION_PRIORITY, d, DESCFLAGS_SET_0);
