Can't Enter Tapered Hollow Cylinders?

I've used hollowed cylinders for a couple portions of my house and I may have found an annoying issue. Both are cut open as well. The "straight" cylinder area I can walk into just fine. I've just discovered that I can't walk into the cylinder that I've tapered; it's as if it's not hollowed although it looks like it is. If I place a chair in it I can choose it and sit with no problem. Has this always been the case?

actually yes. a very old problem and very annoying. certian combinations of hollows and tapers cause the collision to become the bounding box around the object. I know this over a year old. It was on their old known issues page but now that it is gone it needs to be enter into the Jira system.

I know what you mean. I spent a lot of time submitting a bug report on this a long time ago and I guess need to be done again in jira if it has not been done already. I don't think it is just cylinders. The physics engine gets all confussed and just makes it a box.

Tapered cylinders themselves are not necessarily impossible to enter. I built a lighthouse with about 5 degree to 7 degree tapered cylinder sides, and it was fine. So it's probably just certain combinations of taper and hollow that get borked.

One caution - the inside surface of a hollowed prim, if you attempt to point camera focus at it and there is another wall of that prim behind you on the same line of sight, will throw your camera outside the prim. Easy example - make a 5M tall, 5M diameter hollowed cylinder, and stand inside it. Try to focus your camera on the inside wall. Your camera ends up outside, behind you. This is a known bug, that there is no decent workaround for that I know of, other than to line the inside of the hollow prim with other prims.

I also found that some combinations of cut, twisted and tapered box prims have incorrect collision boxes. Take the Library > Objects > Landscaping Objects > "Rock - Large, Angular" object, for example. It's a cut, twisted, hollowed and tapered box prim. I use them for making cave walls and floors. Well, I found recently that in some cases, the hollowed side has a collision box that is a good half meter above the visible surface! You walk onto that face, and you start floating. Strange... In most cases, I solved it easily enough by flipping the prim so the hollowed side was the roof or the area below, and not a surface to be walked upon.

Thanks for the feedback. That is annoying. Maybe I'll see if reducing the taper helps overcome it (while trashing my cool design in the process!)

Ceera, that camera popping out phenomenon sounds familiar. At times when I've stood near the offending prim and turned a certain way I was suddenly looking at the back of the house instead of out the front. So many little things to watch for in this place.

here is one post in Jira about this type of problem. Now if this upgrade of the Havok engine ever happens, maybe this will go away. Which is why I think they do not plan on fixing it.
