The main body of the car is the only thing I would worry about having performance problems with, you may need to break it up into a couple chunks. Don’t go polygon-by-polygon, that’s a waste of time. If you do end up using Retopoflow, focus on blocking out the edgeflow in big sections then use subdivisions to add geometry to round out the shapes. Retopology addons are mostly designed for sculpted character meshes that don’t have organized, animatable base geometry to work from. In your case, for hardsurface meshes I would probably just build the lowpoly mesh out of the highpoly by duplicating it and shrinkwrapping it, then collapsing edges and using the regular polygonal modeling tools. Retopoflow 1 has better performance but the instability makes it a nightmare to work with, and other retopology addons I’ve tried are largely buggy and poorly supported (if at all)… It has the best toolset by far, but I used it for my last character and had to break it up into pieces because the performance was abysmal on dense meshes.

Specified Normals: Enables the use of hard edges based on discontinuities in specified vertex normals between adjacent faces as a constraint. 3ds Max 2022 was released as part of a wider series of updates to Autodesk’s Media and Entertainment software, alongside Maya 2022 and MotionBuilder 2022.Boolean Seams: Uses the Boolean Seams, edges created by the interaction of geometric objects, that are stored in your mesh after a Boolean operation as a constraint.UV Channel: Uses the borders of UV islands as a constraint.Material IDs: Uses the boundary edges of each Material ID channels as a constraint.Smoothing Groups: Uses the edges defined by smoothing groups and hard edges on your mesh as a constraint.You can use Auto Edge to retain hard surface details on your mesh, but the option can also be useful for specifying an important form that you want to retain as well. Auto Edge: Auto edge, if enabled, lets you utilize various types of mesh data that already exist on your mesh through the modeling process as a constraint to influence the output form that ReForm generates.Adaptivity: Controls the degree of local spacial step adaptivity enabling quad size to vary based on the curvature of the surface topology.When the value is set to 0, ReForm will generate more square-shaped polys, which is more useful for hard surface meshes. When this value is set to 1, ReForm can generate quads that are more uniformly square in shape. Anisotropy: Controls the degree of anisotropy allowed in the output mesh.When the value is set to 0, ReForm will vary the size of the quad polygons that it generates to better match the topology it is trying to remesh.

When this value is set to 1, ReForm will generate quad polygons of roughly equal size. Regularize: Controls the degree of regularity imposed on the output mesh.When this value is set to 3, a ninth of the target quad face will be generated, which will then be subdivided at two levels to give the target output result. When this value is set to 2, ReForm will process a quarter of the target quad face count and then subdivide the surfaces to generate a result. When this value is set to 1, no subdivision occurs. Subdivision Factor: Specifies whether ReForm will utilize subdivisions to help generate the target output mesh.Quad Tolerance: Sets the tolerance for deviation from the target number of quads.In terms of quality, these tools outperform direct and wave propagation methods significantly, guaranteeing gap and crack-free results, lower distortion, and smoother maps without shrinkage or volume loss. ReForm is a state-of-the-art quad topology global optimization technology that has been developed by Autodesk. Important: The following options are only displayed when the ReForm algorithm is selected.
