a ? about alpha-izing a plane 3d for terrain

[zerobugetgamemaker]

a while ago i asked about making terrain by applying an alpha to a plane 3d and so on, and it's worked great for terrian, so thank you all for the help on that, but I have a question about it already!

Ok... I'm trying to make a pyramid surrounded by tall thin towers.

what I do:

:b1: set a square alpha to a flat brush and draw five squares. One in center for bottom section of pyramid, and four smaller ones at each corner for the base of the towers.

:b1: I progress gradually to smaller brushes and lighter color as I move up the pyramid. On the towers, I want a more sever slope, so I use a bright white imediately after the dark grey.

:b1: use mgrb tool, apply alpha to plane 3d, offset z.

:ex: It is messed up. The towers are short, and the pyramid has a very tall first layer, and the rest is fine.... any idea what I did?

Seem to me that you're making the pyramid the hard way.

Try this:

1) Start with a Cone3D
2) Turn off Tool>Modifiers>Sh so that the vertical edges are clearly defined.
3) In Tool>Modifiers>Initialize use the following settings:
<UL TYPE=SQUARE><LI>Z Size 60
<LI>HDivide 4
[/list]


Voila! You'll have a ready-made pyramid to use as you please.

A tremendous number of shapes can be created by starting with the appropriate primitive object. You can modify them even farther by using masking and deformations.

it's the same if you want a real 3D volume with a hole !
1)Take the Cylinder 3D !!!
As Aurick said
2) Turn off Tool>Modifiers>Sh so that the vertical edges are clearly defined.
3) In Tool>Modifiers>Initialize use the following settings:
HDivide 4 (if you want for example a window or a thick frame !)
4)Inner as you want
You can also if you are vicious make some "troncated" volume :)

And after "E" key for size in real time in the 3 axes x,y,z the thickness of your real 3D volume ! It's like 3DMax Prog but very more funny !
Very easy and very powerful !
And if you return in Edit "T" mode you can of course make all deformation as you want !
Thx Zbrush :cool:

DOPE! I should have thought of that. The hole purpose of that in the first place was to have the pyramid be part of the ground, but I guess that van be done like this anyway. tnx aurick and frenchy!
