@ BbB : I downloaded a test file at www.blender3d.com, I didn't changed the settings, just changed the shape of the plane and of the cube to match my scene. The results are never perfect, most of the time you have to edit manually the final mesh (though it's just minor things to adjust).
I tried to make the simulation from scratch, but I couldn't get it to work (the fabric stucks on floating above the object like you said... strange).
But if you edit the provided blend file, it works quite well.
I didn't have time to play with the simulation settings much, but I guess there must be some ways to improve it.

I attached some .blend file with this message, feel free to use it like you want.

@ mrCarnivore : each page is a plane, except the cover (If you put a uv texture on a plane, it will show on both sides).

Thanks Docteur, I'll give it a try. I've been playing with inner and outer dampening and I get closer to something satisfying but I need to convert sharp to round edges on my deflection volume for it to work, which then poses me some normals smoothing problems I can't get rid of. I'll post a WIP to make it clear exactly what I mean.

Here it is. See what I mean. I can't seem to be able to get rid of these weird dark edges on the wood "table". This is a Blender subsurfed mesh with subsurf applied, i.e. it doesn't seem to be a mesh density problem... Any suggestion welcome.

That definitely looks like a problem with the normals.

Enable normal display in blender and check them manually would be my suggestion.

Good idea. Will try now. Here's another one without problem though I used a similar volume. Go understand...

I've checked the normals and they're pointing in the right direction, though they seem to show weird angles, i.e. not aligned with the faces. And now I'll stop polluting the Docteur's thread with my amateur stuff. Apologies...

hey no problem it looks good !
I also have some "dark edges" problem from time to time... I still don't know where the it comes from. I was suggested to export the cursed mesh (can't see any other explanation) as *.obj file, than to import it back in blender.
Still didn't tried it though.

If you can use dxf it's even better, it would erase all messy metadata and retain geometry only

I have exactly the same problem with my ceiling fan.
I tried the tip given by DrBouvierLeDuc and it worked !! I exported to .lwo (for some reasons I prefered .lwo), and then re-imported. And it worked !!

Thx !

I claim to be the source of that tip

Some pride doesn't hurt, that's amongst the few things I supplied to the community ! drBouvierLeduc bring it to you and he was right, the place for information is the public place !

So, glad it works, and thnx drBouvierLeduc for reporting that (and for your awesome images too) !

That technique is used also with nurbs when you can not rebuild parametrization anymore because of corrupted data

btw didn't I read that *.obj format do support nurbs and parametric surfaces ?

Cheerz

Ok, I didn't know the origin. So thank you CTZn for bringing this tip to the community as it helped someone

ah what is the fresnel lamp please???

I tried the export-import trick and it worked for me too. Although when I convert a mesh to an .obj file and reimports it, it comes back at about a tenth of the original size...

Stur · Post by **Stur** » Fri Mar 16, 2007 8:34 pm

I exported to .lwo because .obj was requiring a lot of options before exportation.
.lwo exporter just exports without asking questions, the only problem I had, when reimporting, was a rotation problem. I rotated the object 90° and it got back to its original place. The size was ok.
