.obj -> .sur converter
-
@ST: Please don’t mix up things:
- The type 5 part is the convex hull around everything (which you call shrink wrapped)
- It even is there if a shield bubble is included, but it is the same as the shield bubble, since it is the largest part around the ship (convex hull…)
As for the sur splicer: See my last post (maybe you missed it?)
@FF: Also don’t forget the bsp tree, which usually does a major speedup in collision detection. None of the custom generated .sur files had one so far.
Concerning HardCMP: I have one .sur file it doesn’t like, but it’s rather large. Gonna have to look into that some time.

Yes there’s been a flurry of posts, I’ll read them and check and fix my posts.

Mad props to you, Schmack

ok i done some tests tonight
i don’t know if it can be usefull for you but …test on the a9, multipart cmp —> it works like a charm
test on the colony3station (who is pretty big and complex … colony3 station) –-> no way, with several cmp, no differences, no hit registred and no hull detection
test on the avatar station, it seems to work
i noticed one strange thing, maybe it can be important for you to knowat avatar1.jpg, i can pass through
then at avatar2.jpg, i shoot on the base
and at avatar3.jpg, i can’t pass anymore
it’s the same place, exactly
i don’t know what the laser has done but can he “activate” the detection ? -
@FF: Thanks ^^
@Mirkha: Don’t forget that it is attached to root only. I would say that’s why it did not work at all.
Concerning the flying through: I would have to test it myself with the model to be able to draw any conclusions.

Nice tool Schmack, the recent updates make it work like a charm. still crashing on higher poly objects but that does not bother me at all considering sur meshes should not be 9K in poly count.
Nice thing is now that i can use lightwave to create the models, hardpoints, and sur mesh. only using Milkshape to convert the mesh to cmp.
next thing to have would be a tool to convert obj files to cmp, with a scaling factor. now that would be totally juicy to match this tool.
Cheers Mate, two thumbs up.

Just so you know, Schmack, I redid all of FW:ToW surs using your converter, all 124 ships work flawlessly. Not only that, we saw some significant performance improvements
The only thing the exporter doesn’t do are the multiple component .surs but that’s such a small issue.
I’ll do the stations next and tell you how it goes.

I have made a station sur with your soft, and i encounter CDT when trying to fly through, collision are OK but few second after some collision, CDT, don’t know if its the sur or the CMP of my station, will make another test without the sur and if CTD again, then the sur is GOOD and my cmp is crapy lol^^
ANyway, it’s a good job, and you soft let me make good surs for some ships which have previously bad surs
Thanks for your soft

Well i’ve tried this and managed to create a sur that fails every time on every model i’ve tried so far. Clearly i’m doing something wrong.
Process of what i’m doing is as follows,
1. Import model into MS as a cmp. ( Do i need to import the hardpoints as well?)
2. Export model as OBJ file (end up with an OBJ file and a MTL file)
3. Open new converter, import newly made OBJ file
4. Left the number as 5 (no real idea what it does anyway)
5. I tick the second box (because it seems to make sense)
6. Hardpoint section left blank (prob the cause of my errors tbh)
7. Can someone show exactly what needs to go in this section please. All very well saying stick the hardpoints in but how? What’s the format for inclusion? Is it,addon = ge_kf_engine_01, internal, 1
equip = ge_kf_engine_01, internal, 1
ge_kf_engine_01, internal, 1You see my point here? With no documentation how are those who didn’t go to sur school expected to work this out?
Any help appreciated
PS. No complicated replies please, pretend i don’t know anything about surs or this utilty

I was just about to post much the same ^
Interested in this tool… as i have some slightly unconventional ships and a few base models still in the hold due to my severe lack of understanding on anything sur related apart from click here do thisI only just finally wrapped my noggin around LS’s sur builder and its great for most ships as i don’t have many multipart ships… but as i said for a few, stock sur’s and close enough just won’t cut it.
So yeah… I too would love a rundown on the exact steps taken to get a .cmp into MS… to be ready for this tool. do we strip it 1st or just tell it to not import hardpoints… etc, what do the funky values do?.. and all that jazz
-
Gibbon, are you importing the SUR model, or the ship model itself? If it’s the SUR model, I’ve got nothing, but if it’s the ship model… As the internet meme goes, you’re doing it wrong. If you’re importing the ship model, the SUR it creates is far, far too complex, and will most likely hang the game. Use a simpler model in this case. Leaving the hardpoint section blank isn’t an issue, at least, it wasn’t with me.

In what messed up universe is this a small issue? Is this a case of not detecting internet sarcasm, or do you really think this isn’t important?

depending on the ship’s mesh it should for fighters usually not be an issue to convert the whole geometry. for the hardpoints, you don’t need them from the cmp, just write down a list of hardpoint names as you called/want to call them in the cmp itself and you should be fine.
one more question i’d like though to ask myself as well: how exactly to change certain sur part’s attachment to other groups than “Root”? there is an offset, but where is it and do you have to encode the value of the nickname’s hash (or UTF ID) or can you, like in the cons nodes, input a string directly up to 32 bytes?
-
I can’t import the sur model as i don’t have a sur to start with, that’s what the utilty is for lol. Which brings me to the next point you raised, how would i make the model simpler?
@ Gisteron
That’s kind of my point though with the hardpoints, how should it look if i want to put them in, what’s the format? Example please.

I have made about 20 fighter surs so far, have only tested 7 thoroughly. Those 7 have passed 6-8 hour stress tests .
Dev server is setup so that 2 factions fly the same ship with the new sur and shoot each other. Loadouts include guns, missles and torps. Zone set to spawn 30 npcs. Also have a base in the center shooting at both factions. I periodically jump in the middle and shoot at them, bump them with my shield down, and let them shoot me. No errors or crashes.
This is the method I use for fighters…
.cmp --> MS3D :
Import hard points and auto load, are the only boxes I check.
Then export to .OBJ
.OBJ to .SUR converter:
I leave the 1st box at default 5,0
Then I check 2nd and 3rd boxes.
Then enter the hardpoints in the order they are listed in HardCMP.
example:
HpCM01
HpEngine01
HpEngine02
HpMine01
HpMount
HpShield01
HpThruster01
HpTractor_Source
HpCloak01
HpTorpedo01
HpTorpedo02
HpWeapon01
HpWeapon02
HpWeapon03
HpWeapon04
HpWeapon05
HpWeapon06
HpWeapon07
HpWeapon08Going on what StarTrader said about needing the hardpoints in the sur files,
I would think you must enter them or you will run into the random crashes everyone was getting with the previous methods.For larger ships and stations with Vertices over 8-10k I use MS3D’s DirectX Mesh tools or LithUnwrap’s Optimize tool, to lower poly count. The DirectX mesh tools seem to work ok on some models, but not others. For the ones that dont, I Ctrl Z to undo any changes made by directx mesh and save as a MS3D file. Then open the mesh with LithUnwrap, Optimize and save then back to MS3D, weld vertices, export as .OBJ.
I also made 15 or more surs for battleships and large stations last night and will be testing those today. Will report back with results.

I’ll say it once more: this isn’t a magical big button “make perfect SUR”. It requires you to make the simple model from scratch (like you would have done before with the old MS3D SUR exporter) and then use that. Just like I said in the past, this is very likely to be how the original devs did, too.

@ Ben_Kai
Finally someone who understands where i’m coming from. Thanks very much for that, appreciate the heads up.
@FF
To paraphrase you FF, just like i said before, I’ve never messed with surs, used to use resized vanilla ones and it’s only recently i started using Lancers utilty because it does what i want and very easily. You’re assuming way too much that everyone understands this poxy format, and to a new modder what you say still doesn’t mean dick.
The whole point of a utility is that everyone can use it and not just the chosen few who understand the format. So enough with the as i said before nonsense and let’s have a full tutorial of this program so we can ALL use it. Get it?

Acctually I call BS on that one…. Compared to what everyone had to go through before to get a sur that worked halfway decent.
It is quite magical. :lol:
Looking at the original ones I believe they were made like that.
If you want to go through and make 20 to 100+ simple models for all your fighters, capital ships, bases, etc, and waste your time, you can.
You don’t have to…
I have 9 tested surs, using the method I posted above, that I can upload to prove it.

I have appended some sort of roadmap to my first post. This should help to clear some things up.
Don’t forget that this is still a beta and I have to admit I am somewhat surprised that the generated .sur files work that good. I expected some more problems, since I have no clue how the tree of the bit section is created exactly in the vanilla files. This strongly supports that my theory was correct and it is a bsp tree, also the performance improvements FriendlyFire reported speak for it.
Which brings me to my next question ^^ FriendlyFire, how exactly did you measure it? And is it clientside only or serverside aswell?
As for the rest: I will try to use your feedback to generate a somewhat understandable documentation and maybe a more intuitive gui. But I am afraid the hard work of making collision meshes can’t be much more simplified. You can search the web for meshlab and polygon reducing, it has a nice algorithm for that. Sadly I discovered a number of bugs while testing it (mostly crashes), but at least the polygon reducing seemed to work (you have to play with the options). I will try to also include a short explanation how to use this program in the documentation later (or maybe one of you guys finds a better way ^^).
If anyone is not able to generate a working .sur file please hand me the model! Only this way I can see whether there are still errors.
I will have a look at the ones Mirkha postet.

Well this is also an issue which someone should test. In theory a collision mesh build only out of convex elements should be less a performance hit than a polygon reduced one. The important question is, how much difference does it make?
