How do poles affect geometry?
Poles can cause deformations in the surface quality, making “points” where sharpness should not occur
Poles can cause deformation in the surface quality, making “curves” where smoothness should not occur
Poles can affect the magnetic properties of an object and cause unwanted change in geometry
Poles increase the number of tris of an object and is inefficient
If we sharpen an edge, will this automatically be applied?
Yes
No
How do we make sure that surface normals are modified?
Check the normal map and ensure the lines are perpendicular to the surfaces
Go to the preferences menu and tick the checkbox 'apply surface normal modifications'
Object Data Properties > Normals > Click “Auto Smooth” and set an angle
Use the surface normal tool and a prompt will show if the modification is successful
If we position two edges close to each other, how does this affect the surface?
Blender will automatically merge the edges (the distance at which this process triggers can be adjusted in the settings menu) and round out the edge
It creates a pole
It has no effect on the surface is the edges do not overlap and causes an error if there is overlap
It sharpens the geometry in that location
How do we subdivide the geometry?
Geometry Properties > Subdivision
Use the subdivision tool found in the model menu
Create edge loops
Modifier Properties > Add Modifier > Subdivision
If we want to smooth our object without subdividing and setting the smoothing properties, how do we do this?
Go to Object > Shade Smooth
Remove some edge loops
Add bezier curve modifiers
Go to Object > Properties > Smoothness and adjust the slider
Help! I’ve moved my 3D Cursor to a different location and I want it positioned in the center of my screen, how do I do this?
Hold down “ctrl” (“cmd” on Mac) and drag the 3D cursor back to where you want it
Right click on the 3D cursor and choose “reset” in the menu that pops up
Open the Properties panel (“N in 3D View”) and go to View > 3D Cursor and zero out all the properties
Delete the 3D cursor and place another one
Can you duplicate faces while in edit mode?
Yes, by clicking Ctrl-D
No
Yes, by clicking “Shift-D”
No, you can only duplicate objects
Can you duplicate faces while in edit mode?
Yes, this is dangerous but can be easily resolved
Yes, this is a good thing
No
No, geometry in blender is always perfect
Is it possible to have stray vertices?
No
Yes
Is it possible to have stray edges?
Yes
No
Will having an N-Gon that is curved be bad for the surface quality?
Absolutely yes
Not really
No
Can you have N-Gons for flat surfaces?
Yes, this is always the best solution
No, Blender won’t let you
Yes, but it’s ill-advised
No, Unity doesn’t accept N-Gons
Blender operates in what space orientation?
Y-up space
X-up space
Z-up space
7-up space
Which of these is NOT a transform orientation?
Global
Local
Forward
Normal
How do we align two edges or vertices together in edit mode?
Snapping
Moving the edges or vertices until they align
Weld
Screw
What shape do we want the faces to be?
Hexagons
Pentagons
Quadrilaterals and Triangles
Octagons
