Hello Allan,
thank you for your answer.
The problem is how to save all textures without any geometry .
During the conversion every terrain tile is converted and stored into pfb
file without textures in it,
all textures are collected into pfdShare object.After last tile I can
obtain list of all textures with
pfdGetSharedList(shObj,pfTexture::getClassType()).
pfdStoreFile() takes the argument pfNode * . So I need to make dummy
pfGroup and attach all texture to it ?
If yes how ? What function can store the pfList only without any geometry ?
Another way is to generate ascii initfile with names of all textures and
read it in init phase and then load to RM.
But more convenient way form me is to save textures to pfb file.
Do you have any idea ?
PeterO.
