Hi Terry and J-S,
Hi Terry,
Hi J-S. When you convert a file to .flt and then back to .ive, your
PagedLOD nodes are lost.
I meant converting the leaf tiles. Unless I'm mistaken (it's been a
while since I analyzed the structure so I might remember wrong), in a
VPB database, you have a master .ive file, which has PagedLOD nodes
that refer to other .ive files, which might have other PagedLODs, etc.
Eventually you have geometry in .ive files that have no PagedLODs. You
could convert these to flt, edit the geometry, and reconvert. But it
does mean that each LOD of each tile is in a separate file, so it's a
bit of a pain to edit all LODs of a certain region to match (you have
to convert and edit as many files as you have levels, separately).
We have done this for small areas and it works alright ( just editing
the leaf tiles ).
The new .ive file is
also 50X larger than the original and missing its textures, but those
problems are probably solvable.
The 50x larger is weird, but the textures you just have to convert to
.osg with -O OutputTextureFiles to recover them (convert to .osg and
to .flt then delete the .osg file). I don't know if the flt output
plugin has a similar option, I know about that one for the .osg output
plugin so I've always used that.
When you convert from a --TERRAIN based ive file to flt, this gets
converted to geometry. Then when you convert back to ive, you still
have geometry. I don't remember the size difference, but we have
noticed an increase in size.
