STEP BY STEP USE TRANSFER ATTRIBUTES FOR CLEAN UVS
01 Marvelous export Meshes FROM designer
Start by exporting out your meshes from Marvelous Designer. Select the 3D garment in File>export>obj(selected) and ensure Single Object, Unweld and Thin are selected. With the 3D garment still selected right-click and choose Reset 2D Arrangement. This will flatten out your garment into the UV pattern we will use later. Use the same settings in your export and name your files accordingly.
02 IMPORT to Maya and retopologise
Import both meshes into Maya and organise everything by adding them to layers. Select the 2D layout and go to Modify>make Live. This will allow us to rebuild each panel with clean geometry using Mesh Tools>quad Draw Tool. At this stage make sure the edge loops of each part match up – this will make merging vertices later on much easier and result in a much cleaner mesh overall.
03 transfer uv co-ordinates
Now we need to match up the UV space of the new geometry to our original mesh. This allows us to transfer the new geometry to the shape of the jeans, giving us clean geometry and UVS. Select the original mesh and shift-select the new clean geometry. Go to Mesh>transfer Attributes>options. Turn off Colour Sets and put UV Sets to Current. Hit Apply. Repeat for all the panels.
04 transfer clean geo
Our last step is to transfer our clean geometry to our 3D garment. Select the original mesh and shift-select the new geometry. Go back to Transfer Attributes and set Vertex Position to On, UV Sets to Current and switch the Sample space to UV. Hit Apply and the clean geo will conform to the shape of our Marvelous mesh. Repeat this for the whole garment and you now have production-friendly geometry and clean UVS.
