Scale

[PeriapsisPrograde]

If I were to try making some custom parts :-X I'd like to know what scale to build them. What is the radius and length of the stock SRBs, for reference? Thanks

Hi,

Yes, this is an important detail, indeed

Since the parts are all modular, we've decided on a few standards, to make sure all parts will match each other as much as possible. Basically we have 2 standards right now. Later, as more and different size parts are added, we'll settle on other standards as well.

So, basically it works like this: For a generally cylindrical part of size 1 (fits under the pod), we use a diameter of 1 meter. The height doesn't matter as much. If the part will accept other parts, like winglets, to connect to it by the surface, the collision mesh should have 12 sides, so it's possible to arrange parts symmetricaly in 2's, 3's 4's, 6's, 8's and 12's. This collision mesh is then rotated 15 degrees, so that there are flat sides on each axis, instead of edges.

As a general rule, the main cylinder for the visual mesh is 24 sides, but that depends also on the design of the part.

Then there is standard 0, which is for small parts (that fit over the pod), for these, the main diameter is 0.43m, and we usually use 18 sides for the main cylinder. But that, again, depends on design. Currently the only part that uses this standard is the Mk16 Parachute, but later on more size 0 parts will be added.

For parts that attach sideways, like radial decouplers and winglets, there isn't much of a standard format. Those parts can have pretty much any format, so it's just a matter of tweaking until it looks good

Anyhow, we'll release the SDK shortly, which will explain all this in a lot more depth. In the meantime, I hope this helps.

Also, if all the above fails, you can import one of the DAE meshes in the Parts folders, and use it as a baseline

Cheers

I know this is a necro but hey! This is one of the oldest topics on the forums.

Only some of the information above is still relevant, while other parts of it have changed since then. Closed.
