3 years ago ongoing implementation notes:
- approach is to only support reading texture files within RPKs (this is the only thing supported by PRT API, see prt::getTexturePixeldata, https://esri.github.io/cityengine-sdk/html/namespaceprt.html#a2b2c3b2fef77f2d7da8ab5919687507c)
- Houdini requires our custom FS classes to be in a separate DSO in the dso/fs subdirectory: https://www.sidefx.com/docs/hdk/_h_d_k__f_s__add_custom_helper.html
we currently unpack RPKs (at ResolveMap creation time) so houdini can read any resources (e.g. textures) after model generation.
task: implement a "rpk:" schema handler based on this example: https://www.sidefx.com/docs/hdk/_f_s_2_f_s__home_helper_8_c-example.html
(open implementation question: can we somehow reuse the PRT cache for this?)
