I have a scene with two planes; I want the first to appear when the clock is
below .7 and the second when it is above .7:

#if (clock <.7)

plane 1 {...}

#else

plane 2 {...}

#end

But what if I wanted plane 1 when the clock was between, say 0 and .5, then
plane 2 when it was between .5 and .7, then plane 1 to return again between
.7 to .9, then plane 2 between .9 and 1?
How can I do a multisegment if/else or something comparable?
Thanks,
Dennis

you can nest #if like this:
#if (condition1)
<code>
#else
 #if(condition2)
 <code>
 #else
 .
 .
 .
 #end
#end

You can use the #switch, #case, #range and #break directives
Look at item 6.2.6.3

Use switch and range:
