So yeah, this is very strange. When I go to change the base color of a material, I input the exact values given by the instructor. But they've never matched in color. Not once. I always had to adjust manually.

Finally by this lesson, I noticed the slider! So when the instructor says to choose a grey value of .5 I noticed where the slider was (right in the middle, where I'd expect) versus where it was in my blender... but mine was much higher!

Notice in the image below that my value is correct, but the slider is not in the middle. It should be where the green arrow is pointing, but it's not. Any idea why this is happening? It's almost like the values are not weighted properly. It still goes from 0 - 1 but it seems to drop in value super slow until the middle (where it's a value of 0.2 then it drops like a rock after that. doesn't make sense to me!

Thoughts? Hopefully I've just missed something or there is a setting to change. I suppose it IS possible that something has changed since Blender 2.9 came out (I'm using 2.93.0).

Thanks in advance for any help!

and, no. this wasn't a result of me filling in the circle even after the tutorial told me not to. its hard to explain but I extruded the circle, deselected it, selected both edges using an odd method, and extruded it again; so I had 2 extrusions coming from the same place. I ended up just modeling the launchpad with a cylinder.  I could just look it up but I'm also curious to see how questions get answered on this site. (:

Hold down shift + alt + right mouse click

every time I extrude and scale with it it comes off at an angle, is there any way to fix this?

For some reason when I extrude the pentagon, it also extrudes on the Z axis and not just on the X and Y axis.  Can't figure out what I'm doing that's different from the video.  Doing E +S and dragging and it's just changing Z height on it's own.

at 6:26 i can't make the 45 angle to move the loop downward ...and even if i do the g+z key it goes 1 side only.. .Please let me know how to do it.

whenever I tried scaling and extruding to make the launch pad, it keeps pushing my vertices downward and creates faces

Found a useful alternative to select multiple faces like a loop cut under Select/Select Similar/Perimeter

Under View menu found the hotkeys for Frame Selected Numpad . & Frame All Home key are really useful in speeding up my workflow.

When you're using the three button mouse emulator, you can loop select by double clicking instead of using alt+left click. :)

So excited that I know something!! hehe
