|
|
# human-readable source meshes instead of binary blobs. Every *.obj found under
|
|
# Resources/art is baked and exposed under the same :/gui/<relative>.binobj path,
|
|
# so new models just need to be dropped in next to the existing ones.
|
|
#
|
|
# Usage: include(cmake/generate_models.cmake)
|
|
# Requires: target "Telegram" and function "nice_target_sources" to exist.
