Solution to building being solid in SL after upload...?

[Sally Lavender]

Hi, this is driving me nuts as I managed once but never again...

I made a very SIMPLE mesh cube which I made into a base floor, extruded 4 walls and left one bit open as a door. (simply a floor and 4 walls and a opening for the door)

 Upload into SL. I have tried EVERY combination possible: Surface (High/Low/Normal) LOD High etc BUT once the model is in sl is is inprnetrable... behaves like a solid cube.

What am I doing wrong? Is the error already in blender ? I export as Collada file and have tried both from object and edit mode...

The weird thing is I managed it once.... Now the exact same mesh model behaves as if it has an invisible solid box around it.

Any ideas/solutions ?

Thanks in advance :) Has cost me sevral hundred Linden already :/

Other than making it "phantom" I have no idea. Phantom probably wouldn't help your situation though. However you should probably consider uploading it to the Beta grid so it won't use all your in-world lindens to test it out. 

You can find some more information on accessing the Beta/Preview grid here >> click me, I'm helpful! <<

Hi, yea, I also had that, when uploaded they were phantom Is rediculous that it should be so difficult, is nothing more than a prim with walls, so not rocket science I would have given up had it not been for the ONE I somehow managed lol

Did you change the physics shape from "convex hull" to "prim"  after upload? SL uses the hull by default for some obscure reason.

Hi That was the simple solution Works great now Thanks  

But naturally another issue appears lol, the entire building is fine except for ONE section of a wall which has become phantom ....

Did you use the highest level of detail as your physics shape? In that case I don't know why a piece doesn't work, it's one object right?

I'd advice to build a custom physics shape though and include that in your upload, something as basic as possible.

OK. There IS an answer to this and while there have been many posts with lots of explaination and pictures, I can't seem to find them. Sure someone will answer more fully but here is the basic idea.

 

You need to make a PHYSICS model that is made up of just the wall prims, cubes are or planes, not touching. You upload THAT from your computer instead of letting SL determine the physics model (bad, bad idea on house as land impact goes through the roof).

According to my sticky note *wink*, the steps are: "doorway - Solid - analyze- physics dae - change to prim".  So in English that means when you go to upload change the settings to Solid, Anazlize. Upload your very simple DAE file for physics. When you get the mesh into world (Aditi is best of course for all this testing) -- change the mesh from Convex Hull to PRIM in the features tab.

I have done this a time or two but find I don't like making mesh buildings. So I make mesh PARTS of buildings and mix them with prims. Best of both worlds and that has been discussed here often also.

 

So do a bit of research and I am sure you will find more info WITH pictures. Sorry I couldn't come up with a link.

Another thing to watch out for is to check whether you can rez anything inside the building.
