"Error preparing objects to simulate."

LosingSignal

Okay, so I set a scene up with a character (Corin by Mousso), an environment (Tree and Swing Set), and dForce Casual Country Girl.  Pose it up, hit Simulate for the dForce stuff, and I get the ["Error preparing objects to simulate."] Title message.  According to my log file, it looks like something might be wrong with my dForce kernel?  Maybe some model interaction issue?  Or is this a Support Ticket issue?  Has anyone else had a problem like this and fixed it?

Does it simulate from the base pose, assuming it isn't already trying that (if you have the simualtions tart from the memorised pose and that is the zero pose)?

ETA: I reread the OP, I think the error message I've seen is dfferent from the one mentioned. I'm leaving up the rest of the post, in case it is helpful to someone else reading the thread. The message I get is more like, "No dForce objects found" to simulate.

@LosingSignal, I've seen that error message a number of times. Here is a list of things I've discovered will cause that a no dForce object found error when nothing else is wrong.

1. Not all the wardrobe items on the figure are dForce ready, and I've hidden all of the items that are.
   • This seems to be getting more common with dForce compliant clothing sets, I think, where a shirt and/or jacket of an outfit have dForce applied but pants do not. Or a skirt will have it and the top does not.
2. I've simulated an object, cleared the simulation, changed the pose a bit and resimulated several times. Suddenly, it stops working and throws that error message.
3. In the case where I'm using clothing that wasn't sold as dForce compliant, I forgot to add the dForce modifier.

For item 1, make sure the item(s) with the dForce modifier are visible. (You can do them one at a time, if you like, and set Freeze Simulation to On for each as you go.) For items 2 and 3, go back and add the dForce Dynamic modifier. For item 3, if adding back the dForce modifier doesn't fix it, save the scene, close Daz Studio, reopen DS and reopen the scene. And then select the object and apply the Dynamic dforce modifier. Save immediately.

I tried it from the base pose and it simulated fine there, but any other pose I would get the error message.  I tried erasing the whole scene, restarting Studio, then setting the figure back up.  It would simulate from the base pose, but now any pose would make the sleeves jump off the figure and simulate along the figure's back.  Next, I erased the figure and tried just a base Genesis 8 Female character and the clothes.  It seemed to work fine, so I went back to the original figure, where the clothes now just exploded with any pose.  After erasing and reloading again, the clothes now seem to simulate fine.

So, I guess... problem solved?  I'm just puzzled what could cause this.  Software should be more consistant in its errors than this.
