Contact me first, and send the mesh if you can. Superhive's refund policy applies.

- It is built so that it should not: the add-on is pure Python and the engine is a standalone program. - It is tested on Blender 5.2 LTS, and the extension declares 4.2 as its minimum.

No. The engine ships inside the add-on; there is no separate binary to download and no path to configure.

Yes, with no extra tier or restriction. The meshes you make are yours.

Tangent space, OpenGL (+Y), as Blender, Unity and glTF read it. In Unreal, flip the green channel.

Plan to re-unwrap or re-bake for production. Bake gives the light mesh its own maps, and unwraps it first when it has no UVs. Materials and shading do carry over.

Not in this release. Windows x64 only.

No. One-time purchase, perpetual, use it commercially.

No: not to install, not to activate, not to run.

No. The paid version installs over the free one as the same extension.

Yes. NexTopo Free is a separate download. It caps Remesh at 5,000 quads and Project at 10,000 vertices. Nothing expires and no key is involved.

- The built-in remesher refuses a lot of real geometry: non-manifold input, inconsistent normals, near-duplicate vertices. - NexTopo repairs the mesh first, remeshes each separate part on its own budget, previews the result before replacing anything and carries materials and shading across. - Project, LODs and Bake then take the result the rest of the way.
