Use the .dae- the Blender importer likes .dae format a lot more than it likes .gr2. [[File:MeshImportsWithLODSS.webp|thumb|A mesh importing.

The mesh will import in with 1 or more LODS. These are level of detail meshes, intended to be viewed at a distance so they are lower poly. You only need the best quality one as we are making new LODs later, so delete anything that has LOD in the name. | The mesh will import in with 1 or more LODS.

Some people have had success pasting the code from in game meshes into their code, specifically clothbuffer values, which caused the physics to be less flappy and enabled the collider mesh to be exported without issues. Which is worth a try if you have a lot of patience and experience with coding. | Some people have had success pasting the code from in game meshes into their lsx mesh code, specifically clothbuffer values, which caused the physics to be less flappy and enabled the collider mesh to be exported without issues.

'''-LOD Level''' is what level of LOD it is. Meshes generally have no more than 4-5 LODS, usually depending on how 'common' an asset it is. (A common peasant shirt will have many LODS while an armour intended only for the player may have only 1 LOD.) | '''-LOD Level''' is what level of LOD it is. LOD0 is the best quality, cutscene one. Meshes generally have no more than 4-5 LODS, usually depending on how 'common' an asset it is. (A common peasant shirt will have many LODS while an armour intended only for the player or important NPC may have only 1 LOD.) | ||
'''-Lod Distance''' is the distance from which your mesh swaps to the next LOD. For this reason, your highest quality mesh should probably be something like 9-15 metres, your middle ones 15-20, while your last LOD always needs to be set to 0. Or it will vanish from a distance. There are certain cutscenes in Act 3 and elsewhere where your player character is seen from a very long distance, so this is important! | |||
If you don’t particularly care about it performing well on bad computers, you can have no LOD and just set your high quality mesh to have a Lod distance of 0. | |||
'''-Export order.''' Generally all your LOD0 meshes go first, then your LOD1, LOD2, LOD3, assuming you have multiple LOD0 meshes. Look at imported game meshes for reference. If there is not a consistent 1, 2, 3, 4, export order, the mesh will refuse to export. | '''-Export order.'''
