Hi,

here is my _very_ last ;-) question about descriptions.

In GetDDescription I add a parameter via

  
BaseContainer bc = GetCustomDataTypeDefault(DTYPE_REAL);  
bc.SetBool(DESC_ANIMATE, DESC_ANIMATE_ON);  
bc.SetString(DESC_SHORT_NAME, "foobar");  
bc.SetReal(DESC_MIN, 3.0f);  
bc.SetReal(DESC_MAX, 15.0f);  
bc.SetReal(DESC_STEP, 1.0f);  
  
if(! description->SetParameter(DescLevel(15000, DTYPE_REAL, ID_OF_MY_PLUGIN), bc, DescLevel(ID_OF_MY_PARAM_GROUP)))  
    return FALSE;  
flags |= DESCFLAGS_DESC_LOADED;  
return MaterialData::GetDDescription(node, description, flags);

But the parameter cannot be animated: The animation pop-up menu opens on right mouse click, and "Add Keyframe" can be selected---but nothing happens: no red dot in front of the parameter name, no animation.

Thanks for any ideas.

Regards,
jl

Hi,
hmm, seems all correct. Shouldn´t make any difference but try to set bc.SetLong(DESC_ANIMATE, DESC_ANIMATE_ON); instead of SetBool (though this really shouldn´t matter. But hey, you´ll never know ;)
Otherwise I don´t know to be honest.

Hi,

I found out that my problem is elsewhere. If one sets a keyframe in the context menu, GetDDescription is called in such a way that bc == NULL in the following situation, although the parameter "is there":

  
AutoAlloc<AtomArray> ar;  
if (!ar) return false;  
BaseContainer* bc = description->GetParameterI(DescLevel(FX_TECHNIQUE), ar);

My code judged bc == NULL as an error condition.
