David Brasher Posted September 24, 2011 Share Posted September 24, 2011 (edited) I am new to Blender, and it is not being very friendly. It has given me one of the weirdest bugs I have seen. I added collision to a cup model that a modeler made as a static, because I want it to be a havoked item that you can pick up and place and knock over like you usually can with housewares. I got the collision working after several tries so that the cup will not sink into the floor, walls, or other objects no matter what part of it touches the other things. But if I set these cups down on the ground, I discovered that all the nearby NPCs and myself start sinking through the sidewalks. If I do it in a building, all the people sink through the floor and fall into the void. It is sort of like casting the runes. I can cause great mischief with my cups by strategically dropping one. Has anyone ever heard of this happening? Does anyone know what causes it? Can anyone tell me how to fix it?

alonsomartinez Posted September 24, 2011 Share Posted September 24, 2011 How did you make your collision in Blender? Sounds like the physics are messed up http://www.thenexusforums.com/public/style_emoticons/dark/blink.gif Link to comment Share on other sites More sharing options...
David Brasher Posted September 24, 2011 Author Share Posted September 24, 2011 It was made trying to follow instructions from this tutorial. The tutorial talks about swords, but I couldn't find any tutorials talking about cups. I wouldn't think that treating a cup like a sword would cause this severe of a bug. The tutorial said, select your mesh and then click on the grid icon on the options bar (near "view", "select", and "Object"), and click on the "Scripts Window" icon. Then, go to Scripts>>Mesh>>Hull and select "convex", then hit ok. Link to comment Share on other sites More sharing options...
wetblanket Posted September 24, 2011 Share Posted September 24, 2011 Randomly, I was messing around in NifSkope today and noticed the help text that pops up if you hover over a branch. For 'bhkConvexVerticesShape' it says: ...Note that if the shape is used in a non-static object (such as clutter), then they will simply fall through the ground when they are under a bhkListShape. If you examine eg. lowercuptan01.nif in NifSkope and compare it to your nif in another instance then you may find your problem (you can convert/cut'n'paste branches if necessary). I realise you want a Blender solution but if you have no luck then... Link to comment Share on other sites More sharing options...
David Brasher Posted September 24, 2011 Author Share Posted September 24, 2011 (edited) I compared the Nifskope structure of lowercuptan01.nif to the cup I am working on and they seem to be basically the same. No really different lines, missing lines, or extra lines in that block. I looked at that warning message and suspect that it is warning that you should not do something like this: 2 bhkCollisionObject 5 bhkListShape 4 bhkRigidBodyT 3 bhkConvexVerticesShape I don't have any problem with my cup per se anymore. My cup never falls through the floor. The problem is that all the people nearby fall through the floor, which is odd because I didn't edit the people or the floor. I blame it on the cup, because when I do not set it down on the floor, people do not sink through the floor. (There is a lagging effect. Once I set down the cup, the cell is ruined for a little while even if I pick up the cup and put it back into inventory. When I escape the cell and come back, things are back to normal and people can walk on the floor again.)

David Brasher Posted September 24, 2011 Author Share Posted September 24, 2011 The problem seems to be solved. It appears that I had incompatible Blender parts. The program comes in four pieces, if you are using it for work on Oblivion, and the four pieces must work with each other and the type of computer you happen to have. It turns out the wiki and the Blender websites can lead you astray. Don't follow their advice when downloading and installing Blender. Go instead to the page on TES Nexus where you can be directed to a place where you can download all four parts in one compatible bundle with detailed step-by-step installation instructions that work flawlessly.
