Removing hidden geometry and merging redundant vertices.
If an edge does not contribute to the silhouette of the object, remove it.
After exporting your textures from Substance Painter (using the "PBR Metallic Roughness" preset), head back to Blender 2.81. Use the "Principled BSDF" shader to plug in your Base Color, Roughness, Metallic, and Normal maps.
A stunning high-poly model is useless in a game engine without a clean, optimized low-poly counterpart. The Udemy course places heavy emphasis on the retopology and unwrapping phase to ensure maximum performance. Low-Poly Checklist Removing hidden geometry and merging redundant vertices
This is where beginners fail. You must export two files:
Search for the course on Udemy. Look for the "New" badge, check for the resource pack download, and prepare to build your first energy core by the end of the week.

Use Retopology tools by enabling Face Snapping and Target Welding to draw clean, low-poly topology directly over your high-poly sculpt.
Utilizing Blender’s pool of modifiers to cut complex panels, vents, and mechanical joints into the mesh.

Blender 2.81 marked a massive milestone for hard-surface 3D artists. It introduced a revamped sculpting context, improved viewport denoising, and optimized topology tools that streamline the creation of complex sci-fi geometry. Precision Modeling Techniques
The biggest hurdle was shading. Blender 2.81’s Eevee renderer was real-time and gorgeous, but her normals kept flipping inside out. She paused the video, rewound, and realized she had forgotten to apply her scale. A classic rookie mistake. She fixed it, and the harsh virtual light suddenly caressed her model like it was made of machined steel.
