Question about drag occlusion.

[katateochi]

as I understand it, if a part is attached behind another part (using the nodes) then it should not generate drag. Is that correct?

I've recently started a MK3 spaceplane (first one ever) and found that there seems to be more drag along the center line of the craft that I'd expect. Didn't 1.0.1 address an issue with MK3 occlusion?

More drag lines than I'd expect;

Looking inside the fuel tank (in front of which is another fuel tank, the mk3 passenger module, mk3 cockpit and nose cone)

It seems like all the inline parts are generating drag. Is this how it should be?

This is a bug. The stock bug fix modules address and fix this (and many more) issues. Note the current version is 1.0.2 so be sure you have that version. (Bottom right corner of your screen when you first load the game)

yeah I'm using 1.0.2 and Claw's stock bug fix modules (v1.0.2c.2) (I mentioned 1.0.1 as I thought part of that update was addressing this issue, but I may be mistaken about that).

Also, it doesn't occlude all the drag. When two parts are connected by stacknodes, the area of occlusion is the minimum of the facing areas, and that's applied only to the appropriate faces of the cube, too.

Example: an Oscar on top of an FL-T800. The bottom of the Oscar would be completely occluded (result: 0 area for the down face of the cube). The top face of the FL-T800 would have one quarter of its area occluded. And that's it.

Does this occlusion apply if parts aren't totally connected.

For example : I have a Rockamax tank then a small probe core, then a rockamax size heatshield.

Does the heatshield protect the tank as it would do it it have been fixed on the tank itself ?
