Why do you need to retopologize a 3D scan?
Retopology is the process of rebuilding your model to reduce polygon count and to allow for UV unwrapping and proper deformation for animation models. Retopology is widely used by digital sculptors to convert their models into usable assets in game or film projects.
How is retopology used in the digital world?
Retopology is widely used by digital sculptors to convert their models into usable assets in game or film projects. It can also be used on 3d scans for rapid asset creation. Learning the process is quickly becoming a valuable task as more and more game studios are using 3d scans in their asset pipeline.
How to retopologize 3D scans in Sketchfab community blog?
Make sure both meshes are aligned together as well as possible. Then in the render settings, scroll down to the Bake tab and set the Bake type to “Textures” if you don’t see this option, make sure you’re using the Blender Internal render engine. Next, check the “Selected to Active” checkbox.
How can I reduce mesh density in Sketchfab?
This is where retopology comes in – using a combination of the right tools and techniques you can reduce the mesh density while keeping the ‘deep’ realism. Sketchfab Master Johnson Martin explains in this in-depth tutorial.
How to transfer Uvs from source to OBJS?
It is for facial expression scan data reconstruction for a production pipeline which ultimately builds a facial rig for animation. Our source scan data includes marker information which we use to register, build a fused scan model which is used to generate a retopologized mesh for blendshapes.
Is there a way to transfer Uvs between two layers?
No, in MeshLab there is no direct way to transfer UV mapping between two layers. This is because UV transfer is not, in the general case, a trivial task. It is not simply a matter of assigning to the new surface the “closest” UV of the original mesh: this would not work on UV discontinuities, which are present in the example you linked.
