Issue uploading a DAE file with booleans

[Jerreh Howley]

Hello, I'm very new to mesh stuff but I always wanted to learn to make things for second life, so I started working on making a mesh horseshoe as a simple practice attempt.

I used bolean modifiers in blender to cut out some parts of the horseshoe, and when I do this I get some errors when uploading the file ;

I'm not sure what this means so any help would be greatly appreciated. I tried applying the booleans, I tried saving the file as a wavefront than back to DAE, nothing so far worked.

Just a few thoughts. 

Unless that is going to be a REALLY BIG horseshoe  your holes should be textures and not made into the model.  The SL uploader doesn't like little pieces in a model made up of bigger pieces.  

Did you apply location, rotation and scale before exporting? 

Did you use the Linden viewer to upload?  

It isn't the boolean modifier in general. I hardly even use it but DID just a couple of days ago and the model uploaded fine. 

In general and assuming you are new to mesh in Second Life --- just because you can MAKE something doesn't mean it should (or can) be uploaded to Second Life - LOL.    Sad but true.   

 

PS. If your standard size horseshoe uploads at anything other than one land impact something is wrong with the modeling -- so far as Second Life is concerned. It likely would be too much geometry (too many triangles). 

 

Good luck.   Hopefully someone else has other ideas.

Did you make sure "Selection Only" was checked when you exported? Your error log contains references to things like "cubefive" even though those are grayed out in your screenshot.

P.S. Also everything Chic said x1000.

[arton Rotaru]

All of the replies above, and the log says Negative scale detected. Models with negative scale will be rejected. Applying Rotation & Scale as Chic mentioned will fix that. However, if you do that on a mesh with negative scale, your face normals will flip, and will pointing inwards. So you need to reculate outside afterwards as well. Used to be Ctrl + N, in old Blender versions at least.

From the error messages it seems, as Quarrel has suggested, that more then one object was being exported from Blender.

In Object mode with only the Horseshoe object selected File > Export > Collada (.dae) 

Then in the export window top right hand corner open the export options panel (little gear icon),

from the Operator Presets choose the sl+open sim static option. this will set all the exports options correctly for a simple static mesh object including the Selection Only option.

 

Also, as already mentioned apply All Transforms before exporting.

In Object mode with object selected: open the Properties side panel and check that X, Y and Z rotations are all at 0° and that X, Y and Z scales are set at 1.00.

If that are not then you need to correct this by Applying All Transforms see images below :
