Wouldn't that result in twice as many polys that have to be rendered?
Forgive if that's a dumb question, I ain't much of an author, you know. :-)

As a program author, I believe that yes this would result in twice

the polygon count.

While I aggree that programs should generally do everything they can
to make authoring parts easier, I also think that Part Authors ought
to keep in mind that the performance of the programs is a direct
result of the number of polygons that need to be managed.

It's already bad enough, that we can't avoid having many polygons
that represent the insides/sides of bricks that never get drawn
becuase they are snapped on other bricks. Do we really need to go
adding even more by using 2, 4 or more where 1 would do?

I'm new at this so maybe this has been discussed before. Feel
free to fill me in ;)

(...) It's all a compromise (just like life!). If you go creating primitives for every little sub-part that's used a few times, you end up with a primitive directory that's unwieldy & lots of parts which inline because they don't know the (...)
