I suppose one can make a 6 x 6 x 6 prim, and call it a little devil.

From: SuezanneC Baskerville I suppose one can make a 6 x 6 x 6 prim, and call it a little devil. 6.66x6.66x6.66? or 0.666x0.666x0.666?

From: SuezanneC Baskerville I think big prims may reduce the number of triangles your video card has to draw, so it might be faster to draw a big building made from megaprims than one that looks the same but is made of lots of smallers prims. Perhaps someone will clarify that or correct it. As long as the megaprim is indeed created using a base "prim" as the name implies. If someone fakes a megaprim using a skrewy sculptie all bets are off. A 20x20x20 *cube* would have as many triangles as a 10x10x10, so that's 1/8 as many triangles as if you filled the same space with eight 10^3's. Plus it's 1/8 as many objects to transfer over the inet, 1/8 objects to do collision detection/physics on, 1/8 etc,etc. For building buildings megaprims offer many advantages, not the least of which is conceptual simplicity: 1"wall" = 1 "prim". An aside on textures: texturing a megaprim ground plane is an excellent time to use the "Repeat texture every __ meters" option. Especially if you have a floor tile texture and want it to look the same as it used to pre-megaprim, set it to repeat every 10 meters. If you want a different texture, say a red carpet, down the middle, that might need to be done using a second megaprim .001m above the first. 2 megaprims is still better than individual tiles. Wall/roof megaprims work well with "Repeat __ times".
