Light Pointcloud is a fileformat used since Sonic Frontiers, that's used to place lights (.light) in a stage using a collection of instances with resource names.
File Format[edit | edit source]
This is one of the many BINA file formats.
The structure of this format is very simple, it contains a signature "CPIC", the version "2" (no instances have been found with the version 1) and the list of instances itself.
The structure of an instance is
- Instance name, to easily differentiate between different instance.
- Resource Name, to set the MIRAGE Light file name of the instance.
- Position, straight forward.
- Rotation, straight forward.
- Scale, straight forward.
- Unknown value.
Technical Info[edit | edit source]
Since this is a BINA file format, it's very easy to show this type in a struct/memory map it.
struct Instance{
const char* instanceName;
const char* resourceName;
csl::math::Position position;
csl::math::Position rotation;
int unk0;
csl::math::Position Scale;
long unk1;
};
struct PointcloudLight{
char signature[4];
uint version;
int instanceCount;
Instance* instances;
};
