LOD problems (multiple mesh LOD)

hostilis

I'm having trouble implementing LOD's for multiple meshes. I've followed all of the 3ds max methods for creating LODs, I even tried the old method. (http://freesdk.crydev.net/display/SDKDOC3/Creating+LODs)

My case: I have a big house that has multiple mesh group. the main one is the largest which consist of the walls and the roof, the detail groups are the doors,windows and etc. Here's a simplified example:



I've checked all of the pivots, applied reset xforms and double checked all of the links.

In game:


Even if I tweak the LOD ratio the mesh doesn't change. I even zoomed out ridiculously to see if it is working but still it doesn't.

I tried exporting everything using 3ds max 2012 and free sdk 3.4.0 and 3.4.3.

I did some LODs from my past models without problems but all of those are single meshes. I can't combine my house into one big mesh because of the 64k vert limit. my deadline is fast approaching so any help is appreciated, thanks!

oh and please excuse me while I dropkick this cat :poly127:.

It seems that the engine can detect the LODs but it doesn't swap the models even if I change the LOD ratio. This only happens if the cgf has sub objects.



Here's the max source of the model:

any help would be appreciated.

this is a known problem. Dont know if its intentional or not. It wasnt fixed in 3.4.3 so make of that what you will..

They really ought to fix it, its a stupid glitch and makes exporting big complex objects so complicated.
