Hey thanks Matthias!

So... to then set the global pos back into the matrix, I'd go:

  
mg->Invert();   
var backToLocal = mg->GetMulP(pos);   
marr[i]->SetV0(backToLocal);   
  
md->SetArray(MODATA_MATRIX, marr, true);   
  

This is very enlightening and useful but hasn't solved my real query. I was assuming that in finding out the global position, I would get the clone's position during mograph dynamics. But while huge positional/rotational changes are occurring with dynamics, the positional read out of the clones remains the same. So my next question...

Is it possible to determine the position of a clone as affected by mograph dynamics?

Thanks again

Jon

I'm just asking myself the same thing. Must be something with the evaluation sequence of the effector, because the Xpresso node calculates those values just fine.
Very helpful thread BTW.

Hi Sparkle,

I hit a brick wall here I'm afraid, and have since been distracted away from this. Can anyone out there help please? Even if it's a definitive 'it's not actually possible' (which would be a major disappointment)

Cheers
Jon

I'd love to see/know to.
Basically (for me) if it is now possible to get the same data
as from the MoGraph xpresso Data Node.

I haven't tried it, but I think you'd be best to cache the cloner and make sure the object with the coffee tag is below it in the OM. Also switch the expression priority on the coffee tag to Dynamics 499.
That should make sure it calculates after the clones are in position.

Unfortunatly MoDynamics can not be accessed within the COFFEE effector. Caching will not help either because an active cache will disable effectors.

Oh well.

Thanks for clearing it up Matthias.

Ah.. another baffling limitation with Coffee..seems strange that you can do this fine with xpresso.
Thanks for the clarification anyway.

I guess it's time to start learning Python:frowning2:

This has nothing to do with being COFFEE. It's just a limitation of the COFFEE effector itself.

I understand, sorry I'm just a little frustrated as recently I seem to have a knack for trying to do things with Coffee that it can't do and each workaround I try has ended up at a dead end. This has left me with the overall impression that Coffee has not been updated at the same rate as the rest of the program.

@Horganovski: I'm feelin ya! With the previous project I did I was so disappointed every time I found out that some things are just not possible in coffee.
I guess in the end I just have myself to blame for being too lazy for making the leap to C++ but I'd still consider myself rather a designer than a programmer.

@Matthias Bober: Despite my b**ching, thanks again for you helping us with our tedious problems all the time
