Hello, Kabanos.
If you mean the starting Spells and Secondary Skills of Heroes, I don't know how to do that yet.
I know Karyoplasma is creating a program called "Hero Editor" that let's you "edit hero secondaries, specialties and starting army.".
He posted a link to it on page 107 of "How to edit HotA?" thread (I think it is on beta state, and only works for 1.7 for the moment).
I'm glad you liked the tutorial

HotA creatures are actually quite easy to edit.
They are all in the beginning of HotA.dat, you can even see the text description on the right (at least in Hex Editor Neo) which creature it relates to.
It should be fairly easy to figure out what the numbers around these addresses stand for or I can maybe help, if you tell my exactly what you want?
Is hex editing the only way to edit their names and basic stats like number and whatnot? I was looking with MMArchive but could only find the original creatures in CRTRAITS

Cove and Factory creatures + Fangarms, Satyrs, Leprechauns and Steel Golems must be edited in HotA.dat, they can't be edited through crtraits or other txt files.

So I edited a name and now it is crashing when I try to load it. Is there some sort of anti-cheat you have to avoid tripping?
Edit: or do the names need to be the exact same length? I just noticed I accidentally deleted an 06 value at the end of the name, so I'm guess that was at least partially the culprit.
Going to do a bit more fiddling
Edit Edit: I can easily change the name to an equal length name, but when I try to change the length of the name the game no longer loads. I'm only overwriting 00 s so not sure what I need to change to make that work

I might be wrong, but you need to change the length of the string.

There are two main types of strings in this game. With preceeding length (pascal-style) and null-terminated (c-style), so depends which one you are trying to change. Also notice that you cannot wipe any characters following a string.

Okay so I have this: 06 00 00 00 53 65 61 6D 61 6E 06 00 00 00 53 65 61 6D 65 6E 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Which is "Seaman" and "Seamen"
and I changed it to this
06 00 00 00 53 61 69 6C 6F 72 07 00 00 00 53 61 69 6C 6F 72 73 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
"Sailor" "Sailors"
Note I changed what I assume denotes the length of the string in bold.
All I can figure is the sixteen 00 s after the names are important, but I'm not sure what to do about that.

I guess 06 00 00 00 is the length of 53 65 61 6D 61 6E (probably "Seaman", can't convert on the fly). Then the next string follows. So, you have to change the length (06 00 00 00) and the actual string. To make strings longer you will need a pointer to them.

Okay I did it! All I had to do was add an extra 00 after I overwrote the one with my 73.
I didn't actually know you could add (make the file larger without breaking everything) instead of overwrite, but ctrl-c ctrl-v seems to have done the trick

Yeah, congratulations  Was writing a reply In general it depends on how this array of strings is parsed.

Thanks Feeling pretty proud for figuring it out even if it is really basic haha. Most hex editing I've done before is just switching the victory condition in Civ V save files.

Warning  Never do such a thing with an executable or dll. HotA.dat has a custom format, so it allows you to change its length, I suppose.
Or... you've just overwritten something else. You never know

Good to know. I did think it was strange that it worked because I could have sworn I'd read somewhere not to do that. Like you said, just this file I guess. If my game explodes somewhere down the line I'll update my post

It shouldn't. If the parser reads a block of strings it should consider its length, so the next block may be read just after the block of strings. So called consequential reading. In a nutshell, if the whole HotA.dat is loaded into the memory at once, it's OK to make it bigger. And I think it's the case.

homm3 creature modding
Hi Juas and everybody, I am new to this whole modding business. Maybe therefore I cant see the point in modifying hero skills and stuff because this is something even the map editior allows you to do. What I am looking for is a post which transparently shows step by step how to open the lod files to then substitute bmps from one creature of a faction against my own bmps. So that finally my 6 year old son sees himself on the battlefield instead of lets say magies. That cant be too complicated. I did not try any implementation right now but saw in your thread, Juas, that things are more hidden then one might expect them to be. At least I already found the mmarchive, lod tool and much more. But some of the guys producing cove and factory or other mods must be able to showcase how their business works simply in a 5min youtube video for a single detail to be modified, right? Does anybody of you know of such a kind of tutorial? Far off, but closest to this I found the following from one of the vcmi-dudes:
https://forum.vcmi.eu/t/how-to-open-def-sprites/6174/7
Any ideas? Thx a lot in advance!

Don't expect any help from the official HotA Crew, they are the last ones to help you mod HotA sadly.
I can't help you with the thing you are asking either, but hopefully someone else can...

@Nikulani
I'll be a bit brief, but feel free to ask for details.
I assume you can use MMArchive to open .lod files found in the /Data folder of H3, and can preview .def files inside them (such as those of combat creatures: they start with C; adv map ones start with AVW).
Get Defr Preview and Def Tool from here: https://grayface.github.io/wog/
Extract the .def you want to edit or replace, such as Magi. Open it with Def Preview. There should be a panel at the top. Press the 5th button "Extract All for DefTool". Then, open the newly generated .hdl file using Def Tool.
For editing the frames, open them in Adobe Photoshop or Gimp and edit each one of them manually (remember to respect the #00ffff color pixels, which are replaced with transparency in-game). You will also have to add their final, edited outline to the shadow frames, found in a subfolder with a self-explanatory name. Once you're done with all that, open DefTool, press on the big square button with a wrench on the right, and you got your new Def file. You can check it out with Def preview, and if it looks well, replace the original with it in .lod (but you can make a plugin that does not alter the game files, if using H3 Complete/SoD with HD+ mod).
Hope this helps and will make your son happy!

Hi Nikulani!
Good thing that FirePaladin responded you, because I don't know anything about modding graphics. Hope that works for you and your son becomes a new fan of the game

What would be the most straightforward method to edit the sound effects of the dwellings on the adventure map? In particular, I want to change each of the "neutral" dwellings that have the same "sword" sound effect and match them with something more appropriate (e.g. change the Crystal Dragon dwelling to either the Cyclops Cave effect or perhaps the Crystal Cavern). I'm using Homm3 Complete SoD version, not HotA.
