Is there an easy way to skip rendering an object? Like using a GOTO to
skip over it? I don't want to have to delete the whole object or comment
out 20 lines to comment it out.

Thanks.

The easiest way is to simply declare the object as something.

For example:

#declare Thing =
union{
sphere{<1,0,0>,1}
sphere{<0,1,0>,1}
sphere{<0,0,1>,1}
sphere{<1,1,0>,1}
sphere{<0,1,1>,1}
     }

//object{Thing}

As you can see you need only comment out one line this way. This is of course
a simplified version and you would normaly have finishes and pigments for the
objects.

Yes. And another way is: 

	#if (false)
	plane {...
	}
	#end

and another way:
	/* plane
	{ ... }
	*/

  Here's a portion of scene code from a recent trace I did. It isn't my
original idea to call it render control. An artist shared his source with me
and I took to using this method for quick test renders. My apologies to the
artist as I have forgotten his name.

/* Render Control */
#declare Photons_on                =   1;
#declare phd                       =0.75; // 0.5
#declare Area_light_on             =   1;
#declare Refl_Refr_on              =   1;
#declare Focal_blur_on             =   1;
#declare Focal_blur_high_quality   =   1;
#declare Plastic_box_on            =   1;
#declare Innards_on                =   1;
#declare Test_ball_on              =   0;

#if (Test_ball_on)
sphere {<-4,-5,4>,1
   pigment {color rgb 1.5}
   finish {ambient .2 diffuse .6 specular .3 roughness .005}
}
#end // (Test_ball_on)

Aren't multiline /* ... */ comments simple enought? You only need to alter
two lines :-)

I would have given up long ago without them !
