I have the following bit of code:


union
{
	#for (i, 1, Trees_Number)
		#local Trees_Object = union
		{
			PlantPatch()
			scale 1/64
		}
		Populate_Triangle(Trees_Object, 1, Seed, Flip)
	#end
}


The result of the PlantPatch() and Populate_Triangle() macros are 
additional unions. However, I get the error, "No matching } in 'union', 
union found instead". Is there something wrong with the scene? I thought 
unions could contain other unions. Thanks.

You might want to have a closer look at the macros.

Change PlantPatch to an intersection and Populate_Triangle to a difference.
The object will be broken but it will parse, and that might lead you to 
which is your offending macro.  One of those has an extra }

Excuse me, but changing an union to an intersection or difference?
There is no way that can give the same result, ever. It will also render 
MUCH slower.

My guess is that one of those macros produce an union that may be 
missing it's closing brace.

No, the point is not to render it, it's just to parse it to figure which 
of the 3 nested unions is missing the }.  If one changes a union to a 
difference, maybe it says "missing } in difference" and buys one a clue 
to where the problem is.

I changed this:

#local Trees_Object = union
          {
              PlantPatch()
              scale 1/64
          }

to this:

#local Trees_Object = object
          {
              PlantPatch()
              scale 1/64
          }

Now it works. Thanks guys!
