No. Lod Builder preserves your original object and creates a separate LOD set. LOD0 captures the source’s evaluated geometry, while the reduced levels are generated independently from that snapshot. Your source mesh, modifiers and transforms remain unchanged.

Yes. You can use retained-detail percentages or triangle targets, enable reduced levels from LOD1 to LOD5, and process multiple selected meshes with the same settings. Triangle targets are approximate: always check the measured output counts in Results.

UV layers and material assignments are retained where Blender’s geometry evaluation and Decimate support them. Existing materials are shared with the generated meshes. However, aggressive reduction can affect UV seams, shading and small details. Always preview the results; Lod Builder does not generate UVs or bake textures.

Lod Builder is designed for static props and environment assets. Armature-deformed meshes and meshes with shape keys are not supported. Other evaluated animation or simulation states may be captured as static geometry at the current frame, but animation is not transferred to the generated LODs.
