Common mistakes when creating LOD atlases for 3D models include inconsistent UV spacing across LOD levels, mismatched texture resolutions between high and low LODs, and ignoring mipmap compatibility.
Inconsistent UV spacing leads to texture misalignment when LODs switch. Mismatched resolutions cause blurriness or sharpness inconsistencies. Skipping mipmaps breaks seamless detail reduction in real-time rendering.
For beginners, start by matching UV tile sizes for all LODs and testing mipmaps early—this helps catch alignment or resolution issues before finalizing textures.
