Question 1

What is the purpose of 'Edge Creasing' in Blender when used with Subdivision Surface?

Accepted Answer

Controls how sharp or smooth subdivided edges appear

Answer

Edge Crease (Shift+E) sets how much an edge resists being smoothed by the Subdivision Surface modifier, allowing sharp corners.

Question 2

In Blender, what does 'Recalculate Normals Outside' (Shift+N) do?

Accepted Answer

Flips all face normals to point outward consistently

Answer

Shift+N (Recalculate Outside) fixes inconsistent face normals so they all point outward, resolving shading and rendering issues.

Question 3

What is a 'Boolean' modifier used for in Blender?

Accepted Answer

Performing union, difference, or intersection operations between two meshes

Answer

The Boolean modifier uses CSG (Constructive Solid Geometry) to combine, subtract, or intersect two meshes.

Question 4

What does pressing 'P' in Edit Mode do in Blender?

Accepted Answer

Separates selected geometry into a new object

Answer

In Edit Mode, P opens the Separate menu, letting you split selected mesh elements into a new independent object.

Question 5

What is the 'Decimate' modifier used for in Blender?

Accepted Answer

Reducing polygon count while preserving overall shape

Answer

The Decimate modifier reduces a mesh's polygon count automatically, useful for optimizing high-poly sculpts or models.
