Export of characters was the vexing thing here... As for the import, use the newest set of scripts for import (we have it in our tools folder, first page of this topic, but I’m not sure it’s the newest version, you’d have to do your research on that, still, the version uploaded will do) and link the textures. Either set the paths for the texture folder first (...\Mafia\maps) or use the Material Editor (press "M") to find the given texture(s) manually. If you still can’t see them in the viewport, you have to right-click the material thingy in the Material Editor and choose "Show Material in Viewport". Or am I missing something here?  |

| Wonderful progress goin' there, I remember that mod with new re-rendered lightmaps of the levels, who made it? Boz? We should ask him to release some files to add them there. We should ask someone who can modify ls3d to try using multi-core of newer cpus for better performance, game is still lock'd to 63 fps too... |

I think Boz is busy at Madfinger Games, so I'm not sure if he will be able to help.
He's amazing at modding Mafia though, and his Boz mod is incredible, but he might be too busy at least at the moment. |

Yeah, that was him, he even had some tool for baking them (we tried MWE but somehow that did not work out).
I don’t know anything about engine modifications but a completely new engine would be nice.
You can unlock the fps using the newest version of the Widescreen Fix. https://thirteenag.github.io/wfp#mafia |

You should really try this yourself... Bake some in different places in different resolutions, compare what you see in the program and what you see in the game. Or ask in the MWE topic... For all I know, MWE is the only tool that is able to bake lightmaps. I remember we even talked this over with Boz a bit but we were never able to even characterize the problem. God knows what causes it... Maybe there isn’t any. |

| I thought about giving Mafia modding a try, but I don't know a thing about how to get started or how it works, plus I'm in school currently, so I'm pretty busy most of the time. |

Full import of the map from mafia 1 to 3ds max would not have prevented. |

Do you mind posting a screenshot along with the exact lmap settings you used? |

Sorry, no time to do that again. But it should be easy to replicate (and maybe clear out a few things). We really tried all kinds of settings combinations to determine what’s going on -- I mean every single combination you can think of. The city is one chapter. Though you can’t really see the settings, https://1drv.ms/u/s%21AoO553Xc23G7iHNA7iqPEU_liNl2 these are some "test" we have done. You can take a look at 1-18 and M1-M18. Different levels of shadows (going up) in MWE and in the game. You can for example see that 16 seems more detailed in the game, though 18 should be the more detailed one. The basic idea is that it never looks the same in the game and in MWE. (I have another set of screenshots for the bank mission https://1drv.ms/u/s%21AoO553Xc23G7iHLphEigk6vM_r1z). For example the shadows the window casts -- in MWE, it looks very detailed, including the "bank" lettering, while it’s blurred in the game. Then there were problems with different edge bugs. You can see that on dd15 for example. The place under the Giuliano Bridge was a problematic one as well (out of what we tried). "The same" case with the standing ashtrays at the bank or round tables on the steamer. Normals are correct but when we created lightmaps for these (no matter with what settings, we tried them all), as there was one in the original game, there would always be an edge on the body. So firstly, the level of details seems to work strangely and then there are those edge artifacts.
We also later established (looking at a black shotgun right under a light at Vincenzo’s) that what they may have done at IS was first setting up lights for creating lightmaps, baking them, getting rid of those lights, and only then adding the lights that are actually there. Which would be yet another problem when recreating lightmaps for new models (thank god nobody’s working on anything). Moving the lights of course changes the edge problems, so we tried stuff like moving the model somewhere, lighting it somehow, baking the lightmap and then moving it back. But it never really looked good, so we just left it... But that wouldn’t really be a problem of MWE.

| Hopefully the lightmap issue is fixed in the next update for MWE if there is no workaround, but as long as it just looks good then we should be glad. |

I don’t know, maybe it’s not a bug at all. Somebody should test this in a "clean" scene, a newly created one, with new lights and so on, to determine whether there even is a problem. Who knows what are the causes in the cases I mentioned... But this somebody is not going to be me, sorry. |

On regards of the buildings in Mafia 1, there must be well over a hundred unique building models including the prison, church, prosecutor mansion, car lot, barn, Sarah's house, Paulie's apartment, Salieri's and Morello's bars, etc. It'll probably a long time before we even scratch the surface in remaking the models.

Thanks a lot for the detailed explanation, Honza_B.

It looks like the game scales down lightmap textures. The game possibly has a hardcoded maximum size for lightmap texture atlases and scales down any patches that are too big. If that's indeed the case, increasing the tessellation of the mesh should help as that allows MWE to allocate smaller clusters for the individual lightmap patches and hence stay within that size budget, at the cost of increased drawcalls.

The hard shadow edges in dd15 are due to discontinuities in texture space. MWE allocates the faces at that shadow edge to different clusters (i.e. allocates different textures for them) in order to stay within the texture size budget that's configured via the Size option. Discontinuities are a general problem with lightmapping. There're ways to mitigate these effects but none of them are implemented in MWE. In case of dd15/16 you could work around them by increasing the texture size budget.
I'm unable to reproduce the edge issues you had with the ashtrays or round tables so far but maybe I just picked the wrong examples. I only tested with the vanilla models, though.

That's my impression, too. I have come across such a setup in mise18-pristav. Rebuilding lightmaps for &&podlaha06 does not reproduce the sun light that floods in from the two open gates. However in that case it seems they didn't delete any lights but rather removed sector &&podlaha06 from the light sectors of the main directional light after they had created the lightmaps, possibly in order to prevent ~barel12507 et. al. from being lit. Readding that sector to the list fixed that and enabled MWE to properly reproduce the lightmaps as seen in the vanilla mission. Maybe it's a similar issue with Vincenzo's workshop and other places where you've encountered this phenomenon. |
