Hello :)
Welcome to CS,
1.) if you have the line engine->SetLightingCacheMode (0); in your code, you
can remove it. The next time you run your application, run it with the
command line switch /relight. It will take some time to load but the
lightmaps should get cached and the next time the application should load
the cached light maps without running a full relight.
2.) The way blender2crystal makes libraries is a little misleading. Firstly
it makes a Texture folder within the .zip file and places the textures in it
but the CS Engine actually looks for the texture on the VFS. If you edit
your library you will see the lines for texture:
<textures>
<texture name='ninja_test_model.png'>
<file>/lib/textures/ninja_test_model.png</file>
</texture>
</textures>
You will notice that my code above has the extra /lib/ portion in front of
textures. This means to load my textures from my library file and not my
Textures file/folder that is defines as @data/Textures within VFS.cfg.
So, you can either change the place the CS Engine looks for the texture,
then re-add the library file back to your (library).zip file, or you can add
the texture file to your (texture).zip file.
Hope thats not too confusing!
