Can Snapping Help Seal Gaps?

Recommended Posts

Trying to create a large "Cube" building where my characters will converse.

 

I create six simple Cubes resized to 5x150x200, (size irrelevant for this scenario), and place them all together into the shape of a Cube.

 

Next, when I go into the finished structure, I can almost always see beams of light sneaking in along seam lines here and there. So, I hop back out of the structure, and start zooming in, way in to align the walls as close as humanly possible, but, no matter how many times you keep zooming in further, you keep seeing that you need to nudge, and slide just a little bit more to make the, "perfect" seal.

 

Is there a more, "politically correct" way to achieve the perfect seal I seek?

 

At first I would say, "snapping" is the ideal answer for what I am looking for, however, after researching "snapping" in Cinema 4D, I find that not many folks are advocates of Cinema 4D's "snapping" capabilities.

 

How should I be "sealing" those six panels perfectly?

There is nothing wrong with snapping in Cinema, particularly later versions, and it can help with this to some degree.

However, by far the best method of avoiding light leaks is to use contiguous geometry, so don't build walls out of separate objects unless you absolutely have to - instead make a whole room out of a cube (for example), where you have reversed the normals so that its inner surfaces become the 'outside' of the object so to speak and you make all the walls, the floor and the ceiling out of 1 cube (or rather I should say 1 object). That containing geo can also have thickness if you want to double insure against light leaks, but it's the contiguousness of surfaces that is the biggest factor...

 

Here's a quick example room with 2 windows and some extruded thickness I knocked up from a single cube, that will only let light in through the windows or the missing front wall...

Of course you can still build anything inside the room out of separate objects - skirting boards, windows frames, coving etc because all that remains nicely contained within your leak-proof outer shell of a building...
