Retopologising the Garments

Retopologising the Garments



Before retopologising the Marvelous Designer simulation, I researched into the best method for doing so and found an in-depth tutorial from 3D Gladiator found here: https://www.3dgladiator.com/tutorials/marvelousdesigner/

Simulated garment export:



Flat garment Export:



The tutorial process involves exporting both the simulated and flat garment geometry from Marvelous. This is then imported in 3DS Max ready to be retopologised. To keep things simple and clear, I exported and retopologised all of the garments separately to stay organisefd.


Simulated and Flat garments imported into Max:



 Retopolgising the flat garment geometry using Max's freeform tools:



Below is the final scene required to retopologise the garment using 3D Gladiator's script. 

Basically what the script does is takes the retopologised pieces of the garment, seperates them into individual objects, aligns them with the flat Marvelous geometry and applies a skin modifier to them so that they can deform together. 

Then, because the simulated and the flat Marvelous meshes share the same topology, the flat geometry can be given a Morpher modifier and morph to the same shape as the simulated pattern. 

Finally, because the retopologised geometry is skinned to the flat geomtry, they will deform together, leaving the retopologised meshes perfectly aligned to the simulated meshes. 

By using this method, not only is the geometry even and well aligned, but the UV's from the Marvelous Designer garments are also transferred to the low poly.

I decided to leave the geometry quite low poly so that it would be easier to manipulate in ZBrush.




This can be seen clearer in the video below:


For more information on the process, check out the tutorial from 3D Gladiator.


After all of the garments had been retopo'd and morphed, some cleanup was required in order to weld the pieces together and make sure they all lined up and the topology was uniform throughout.

I wasn't too bothered at this point if pieces were slightly overlapping as I would fix this inside ZBrush, and the parts that would never be seen would be deleted.

Morph Target Practice

Morph Target Practice In order to find out if the my idea for my project would be feasible, and to understand the process of animating the morph targets on my character, I carried out a basic test in Unreal Engine 4. Firstly, I created a deformed variation of my model in ZBrush using the same mesh, so it had the same geometry and UVs. I then exported both the high and low poly models of the man and deformed man, then imported them into 3DS Max. I used the Morpher modifier in Max to pick the deformed mesh for my model to morph into. I then exported the original male mesh ready for use in Unreal. Inside Unreal Engine, I used the Normal maps for both of the models, which I had previously baked in Substance Painter, and set them up to blend in a material. I then made an instance of that material so that I could change the properties of the parameters I had exposed. Inside Unreal, I used the 3rd Person Character template to give me a start with a ca

Tertiary and Micro Details

Tertiary and Micro Details After finalising the secondary forms of my sculpt, I went on to adding all of the tertiary and micro details using alphas, surface noise and hand sculpting. I utilised the use of Texturing.xyz alphas as well as some free brushes and other alphas found online.  The process is fairly straight forward, I added a new layer for each detail that I was working on so that I could easily adjust and blend the mutiple levels of details. I then used the alphas with the standard brush set to drag rectangle then worked my way around the model. I kept the details generic and broad at first, then went over them again with more care and attention. When starting off applying tertiary and micro details, the mesh feels really smooth and empty, so I added some  surface  noise to the mesh before hand to break up the mesh a bit and make it less pristine. This also helped add a more organic feel to the model. From a distance the skin detail isn't t

Transformation Animation - Animating in 3ds Max

Transformation Animation - Animating in 3ds Max I decided to animate the morph of my character in 3ds Max using the morpher modifier and the rig from Mixamo. I chose to animate in Max, rather than handling all of the morphs in Unreal as it was quicker this way and I was more confident using Max when it came to animation.  I experimented with a few different animations first to get a feel for how I wanted my character to move and react to the transformation. I made sure that the iterations were rapid so I could rule out what I did and didn't like quickly. When it came to using the Morpher modifier, animating the morphs was fairly straight forward as each morph slider could be keyframed, meaning that it was just a case of setting where I wanted each morph to start and stop. I was originally going to have a transformation including the entire body, however as time went on I realised it would take too long to achieve, so I decided to just stick to the head. The biggest
