.obj -> .sur converter

i have “disassembled” Port Franc 1 (large station) in some pieces of station, to make a “wreck” and use your software with hardpoints checkbox uncheck. The Sur seems to be good in HARDCMPViewer, InGame, Hit detection is OK, and collision detection work 3 or 4 secondes, then FL freeze when i try to pass in he "wreck, without make any collision.

I can upload the model if you want.

Here is a screenshot of the CMP to understand what i mean :

and a screenshot with the generated SUR:

@Sushi: Did you encounter no bugs in collision etc? I have Mirkhas model here which does not work correctly. But it’s the only one so far. At least I have a proper testcase ^^

@Ezekiel: This sounds like the one known issue. Should be fixed in the next version which I should be able to finish in the next days.

Nope, haven’t had a problem with any collisions even with some of our bigger models

@Ezekiel: i had that problem, too, with lancer’s sur_builder. btw the sur you have there rather is built with the sur builder, at least it looks like it is. Schmackbolzen’s sur conversion software would not generate a sur geometry, it would convert a geometry you input to it to the format of freelancer hitboxes.

The sur you see in the picture is built with the schmack software.

this is the steps i have followed :

open the ms3d station model
regoup all meshe in 1 group
export as .obj
use the software with default values, without check any options and of course wthout naming the hardpoint.

Yes,
the CMP is in attachement.
Hope this can help you.

So, any news ?

OK, good news so, i will remove doule vertice myself for now.

And good luke for your exams

Firstly, i said i wouldn’t be back but here i am. The reason for this post is a simple one, to show you what i’ve done with Schmackbolzen’s utility.

Now i wouldn’t even bother posting this if it wasn’t for one person and one person only, that is Ben_Kai. I got so annoyed at some people in this thread for their know it all attitude and their collective assumption that we should all know how to use this utility. Utter nonsense. Very few people can use this utility properly without some instruction and the information posted so far is …. lacking, at least to someone who hasn’t got a clue about sur files.

The real hero as mentioned is Ben_Kai. He sent me a tutorial on how to use this utility that even my cats can understand, and imho this should be included with the converter because then EVERYONE can use it and get results.

Enough ranting, onto what i’ve accomplished. A new asteroid base with flyable interior. Now when i first put this model into my universe, it had the annoying habit of vanishing after about a 60 degree turn. I thought it was the sur file causing this, so i made one with LS’s utility, same problem. The model was saved as a single group model.

Next up i thought i’d save the model again, this time as a multi group model, five parts to be exact. Now it works fine. Interestingly the sur file is the one i made for the single group model but works perfectly well.

Points of interest, it’s detecting every undulation on the surface of the asteroid, also the fly through entrance as well with all the various internal parts properly covered by the sur which the utility accurately finds. There is no cheating going on here with the use of the phantom physics command. I’ve tested this base in a full battle environment and all parts receive hits, external and internal.

It’s a top utility, that with the brilliant tutorial i have and a copy of Lithunwrap, makes perfect surs.

@Gibbon

Nice work mate. Nice Work. mind sharing that tutorial?? or a link to it or something? that is cool stuff.

You ran the original model through FL Model Resizer? It sounds like it was being culled by the game because it didn’t have a radius.

Great news that you’re able to use this incredible tool.

@ Sushi

I don’t remember doing so, but least i know the multipart version worked.

Here’s the tutorial made by Ben_Kai

MODEL PREPARATION

1. Import CMP into MS3D. “auto load”, is the only box I check. “Import hardpoints” is optional

2. Use DirectX Mesh tools to remove some triangles. Move the slider, for most models it will only reduce by 5 - 10%. Click the save button that has the - sign.

(Note on above: If the model is low poly to start with, you can ignore 2 and move onto 3)

3 . Export as .OBJ. You can try to import back into MS3D and use Dx tools again, but I usually just reduce more triangles with LithUnwrap. I’ve noticed that using DX tools numerous times begins to degrade the model to the point where your SUR will not be very from fitting. For small fighters this is fine. But for larger ships and stations I think It kind of defeats the
purpose. I guess you could delete some triangles manually inside the mesh but I’m not a modeler so I dont attempt it.

Close MS3D.

LITHUNWRAP

4. Open .OBJ with LithUnwrap. Go to File - Model - Open. Go to Tools - Optimize model. Check all 3 boxes, click OK.

5. Save mesh as .OBJ. Go to File - Model - Save. Make sure format is .OBJ.

6. Import .OBJ back into MS3D.

7. Go to Edit - Select All. Go to Vertex - Weld Together. Make sure you dont skip this step or your SUR could have huge holes….

8. Export as .OBJ

OBJ CONVERTER

9. Select your .OBJ. I leave 1st option at default. Check 2nd and 3rd boxes then input your hardpoints. I will add that on bases i haven’t had to add in hardpoints

10. Job done

Thanks to Ben_Kai for the tutorial, if i can use it then anybody can.

Programs used, Milkshape, Lithunwrap

Awesome stuff, thanks Gibbon.

I have a few capital ships that will benefit from this method.

i have had some really good luck with this tool and simpler sur files so i am looking forward to giving this method a go.

Cheers mate.

Gibbon, glad you did come back. Hope you keep coming and keep contributing.

Would you mind posting your sur file and cmp file please, I am curious to see how the interrior surs are constructed, as they are working well for you?

Thanks in advance.

schmackbolzen: Good luck with your exams, best wishes.

ST - you made a spelling mistake!

Yes, so I did!

It’s hard using that hand in my mouth to hit the keys, it’s still fresh and not rigor-mortis’d yet!

Thanks for the tuto, it works fine with some models i have tested

Schmackbolzen make an awesome tool, and this tuto make it easy to use

Thanks a lot for the work

Okay, for the Discovery mod I’ve used this tool to rehitbox 205 custom ships (and counting). So far, no problems, although hitbox testing is still ongoing. Some thoughts:

Someone mentioned shield bubbles. Those are seperate SURs assigned through the shiparch and the corresponding shield entry in select_equip. Would be outside of the scope of this, although I see no reason why this tool should not be able to create a hitbox of a very simple egg shape. Point being it’s a seperate model entirely, and not part of the ship itself.

Being able to assign named components so destructable models and hitboxes moving along with animations can exist, would definately be a plus. That’d make bases with animated bay doors possible.

I’ve fed the tool clusters of convex shapes (basically, when supplied a model, I manually break it up into pieces, use Milkshapes convex tool to wrap a convex untextured shape around them, and delete the original shape). Noticed if I don’t check the box to use convex hull instead of splicing, the SUR tends to get a lot larger. Not sure why.

@ Gibbon

Glad you got it worked out and decided to come back! Snazzy lil rock base!!
