Why do my cars have weird shaped shadows like these? I import as shadow meshes the same models I use for the main meshes.   |

hi! I'm sorry, I'm not understanding or seeing an issue in your pictures... can you point out or explain a bit more what is it you're referring to?
edit: oh wait,I assumed both were your cars. please provide the package and blend file so someone can take a look.

Hey Lory I already showed you a solution in Telegram but I can show it better with this pictures I hope:
1 - Decimate your Mesh to half of the normal poly count or a little bit above.
2 - Apply the Decimate changes.
3 - Go into "Edit Mode" and select everything with "A"
4 - Duplicate it and Apply it with a short right click
5 - Click "CTRL + F" and choose "Flip Normals to flip the duplicated Polys.
6 - Now you have a double sided mesh that solve the shadow issues. It needs to look like the picture.
7 - Go back into "Object Mode" and resize the mesh with "S" to make it smaller than the normal NON-Shadow LODs.
8 - Save your Mesh.

I know this issue, he means the wierd scratches inside the shadow which shouldn't look like this. I got the same issue a year ago with my cars and solved it with the method I posted in pictures. |

ooohh!! mm I see.thanks! have you tried only decimating? duplicating and flipping seems pointless to me.

Neither decimating polygons or flipping normal seem to work. Any other solution? I keep creating but my recent cars' shadows always have that issue in game

Can you share a .package with the issue so someone here can take a look at it?

It looks like it's something with the structure of your shadow mesh. I used a solidify modifier on it then decimated with a factor of .25 to get the polys back in the range of your LOD 0. It helped, but there are still some little jags on the shadow. I don't think it's quite as noticeable through.
Maybe try filling in the space under the car?I was messing around with filling in the space under the car for my own curiosity and realized your shadow mesh wasn't uv mapped properly. I deleted the the ground shadow from your mapped LOD 0 (High) mesh, joined the glass and car groups, and changed the cut value to zero to create a Shadow LOD. That completely fixed the issue   |

That completely fixed the issue What do you mean when you say that it's not correctly mapped? My meshes are based on the Centurion cupboard, meaning they have CUT 2 for the flat part on the bottom, CUT 0 for the main mesh, and CUT 1 for glass parts. Usually all I do is literally deleting flat shadow and glass parts and then I import the solid car, and that seems pretty similiar to the way you described your process (the only difference I see is that you joined the glass parts instead of removing them). |

This is what the UV map of your LOD 0 (High) car mesh looks like in Blender:  This is what the UV map of the shadow mesh looks like in Blender: (like it hadn't been mapped at all)  When I used your properly UV mapped mesh to create the Shadow LOD, the shadow appeared without the jags in game. I don't know if you need the glass group for the shadow, but it worked when I joined the two groups together for the shadow mesh. |
