Making a Dynamic Gown for Poser Cloth Simulations


This tutorial assumes that you have already made your gown mesh in a 3D modelling application such as Wings3D, Blender, Zbrush, 3ds Max, etc. It picks up at the point where you have imported the OBJ mesh into Poser. You can preview the finished gown below and the end of this tutorial.

Here is the gown mesh I made and imported into Poser.

Gown mesh imported into Poser

I basically exported the V4 mesh from Poser and imported it into my 3D modelling application and then model the garment while using the imported V4 mesh as a reference base.

When you import your gown mesh into Poser and load your figure, you might find that the mesh does not fit the figure exactly, which is the case in my example here. You will have to do some moving and scaling. Just do the best you can. The cloth room will take care of the rest once we run some simulations. Here, I scaled and moved the gown so that it fits V4 the best it can.

Next I go into the Cloth room, set up a new simulation for the gown and set V4 as the collision object.

Now I run the simulation. It will only take a few frames for the gown to be fitted. I stopped the simulation at frame 3. I don't want too much draping. I just want the gown to fit..

Now I can save the fitted gown by selecting the gown and then, under the Object menu, select Spawn Morph Target.

Spawn a morph target

I name the morph "Fitted".

I then slide the time slider back to frame 1 and change the Fitted morph dial to a value of 1.

At this point, I can go back into the Cloth room and delete my simulation. You will notice that the "Dynamics" dial is gone on the gown's object properties window. Since I have spawned a morph target and set it to one, the gown will remain fitted even once the cloth simulation has been deleted.

Now I can parent the gown to V4's chest and save the gown to the props library as a smart prop. A smart prop is simply a prop that is parented to a figure. With the gown selected, I choose "Change Parent . . " under the Object menu and then select V4's chest as the object to parent the gown to. Then I save to the props library and answer "Yes" at the dialog box asking about saving as a smart prop.

Now I have a gown I can use for future simulations. I can now close the document window.



Running Future Simulations

Now I open up a new empty document. Once I load my V4 figure, I load the fitted gown prop from the props library. The gown should spawn on to V4 and fit her perfectly since I have parented it to her chest and dialed the "Fitted" morph to 1 earlier.

Now I can go into the cloth room to run a new simulation as I outlined in the steps I did before. This time, however, I will let the simulation run a lot longer. I create a new simulation by clicking on the New Simulation button and click the Clothify button and clothify the gown and assign V4 as the collison object. Then I move to frame 20 and apply a pose to V4.

Next I go back to frame 1 and begin the simulation. You can change the cloth settings as desired before you start the simulation, but I will leave the settings at their default values in this tutorial. I start the simulation and let it finish at frame 30 so that the gown properly drapes over Victoria. And here is the end result.

Finished cloth simulation

Here is the gown simulated over 710 frames. This took quite a while to render but the result is definitely worth the effort.



Well, that wraps up the tutorial. If you find this tutorial helpful to you, please show me some love by making a donation.
