And there-in lies the key... read from bottom to top....
Simplifying the base-clape3 model
<animation>
<type>range</type>
...
</animation>
<animation>
<type>select</type>
<object-name>redlight</object-name>
<condition>
<greater-than>
<property>/sim/time/sun-angle-rad</property>
</greater-than>
</condition>
</animation>
<animation>
<type>billboard</type>
<object-name>redlight</object-name>
...
</animation>
<animation>
<type>dist-scale</type>
<object-name>redlight</object-name>
<interpolation>
...
</interpolation>
</animation>
the interpolation animation on *redlight* would be performed first,
then the billboard animation on *redlight*
then the sun-angle conditional animation on *redlight* (in this case to turn
it on when the sun is below the horizon)
then finally setting the range that the whole model is visible from
yeah???????

I verified in the code and it looks like the condition is honored in most
animations.
if you want to conditionally translate :
<animation>
<type>translate</type>
<object-name>myTranslatableObject<object-name>
<condition>my condition</condition>
...translation params...
</animation>
You second case :
<animation>
<type>rotate</type>
<object-name>myObject<object-name>
<condition>my condition</condition>
...rotation params...
</animation>
<animation>
<type>translate</type>
<object-name>myObject<object-name>
...translation params...
</animation>
In this case, the object is first translated and then conditionally rotated
because the animation execution order is bottom up ( last in xml file
applied
first - this has to do with own animations are inserted in the original
static
model )
