Teeth Spikes
by Amber Light

One may somehow get confused when trying to place teeth spikes in knowing whether they should be set-up horizontally, vertically, etc,

I - THREE MAIN QUESTIONS 

Basically, you must answer the following questions :

1-Room orientation : is your room oriented North-South (ie. 'horizontally' in the Editor) :

or East-West (ie 'vertically' in the editor) ?

2 - Which direction Lara is looking to? 

3 - Do you want spikes to stick out and in alternately, out constantly, or out and back in once only?

OCB settings will depend directly on these three points.

II-OCB SETTINGS : 

Below are the OCB values to be entered in the teeth_spikes timer field, according to the answers to the 3 questions above :

1 - Room oriented North-South with Lara looking northwards :

Spikes out and in alternately, Spikes out constantly, Spikes out and back in once

2 - Room oriented North-South with Lara looking southwards :

Spikes out and in alternately, Spikes out constantly, Spikes out and back in once

3 - Room oriented East-West with Lara looking eastwards :

Spikes out and in alternately, Spikes out constantly, Spikes out and back in once

4 - Room oriented East-West with Lara looking westwards :

Spikes out and in alternately, Spikes out constantly, Spikes out and back in once

Reminder : select the teeth_spikes object, press O and enter OCB value as below :
