Func_Msgboard: OBJ-2-MAP V1.1

Posted by JneeraZ on 2015/05/24 18:23:54

So I added a few new features to my OBJ-2-MAP utility and put together a small web page explaining how to use it.

This is a utility that can take OBJ files exported from any modeling app and convert the geometry inside into Quake brushes.

Have at it! I think everything will work.

Ha, awesome! Thanks for heading that up, I appreciate it...

Wow, that's amazing you were able to decompile the whole thing :o

So it is actually an openable project now?

#43 posted by khreathor on 2015/08/04 22:56:21

.Net decompilers are very clever these days.
Yup it's a whole VS project, decompiled to C#.

Patch

Hey!
I'll prepare git repo next week.
Sorry you need to wait, I was extremely busy last days and I'm heading on 4 day holiday atm, so I'll be away from computer till Monday (I'll lurk from mobile ;) )
Here you have binary, so you can use my latest changes:
http://78.47.23.219/OBJ2MAP_111.zip

It saves settings to XML file (OBJFileName.xml) when you hit GO! and load settings when you choose OBJ file.

Happy mapping!

Blender OBJ Export?

#45 posted by ShoTro on 2015/08/23 15:14:33

I have tried many times trying to get blender OBJ export to work with this tool, but each time I get a NullPointerException in the debug window.

#46 posted by JneeraZ on 2015/08/23 16:26:56

Shoot me the OBJ file and I'll see what I can do about it.

ShoTro have you tried this build: http://78.47.23.219/OBJ2MAP_111.zip ?

I have used it with blender and had no problems.

Hey Kreathor

Could I grab your decompiled source? Wanted to play around with a few things.

#49 posted by adib on 2015/10/01 18:50:04

What languages/tools you used for UI and code itself?

AFAIK It's C#

eric

There's a repository that Kreathor set up over here ...

https://bitbucket.org/khreathor/obj-2-map/wiki/Home

The source has actually been updated and had a few features added ... so you contributing to that source tree would be ideal.

Ah, Cool!

#54 posted by ericw on 2015/10/01 20:24:05

Looks like it's a private repo, I just asked kreathor to add me.

I'm going to try doing import of UV's and texture names from the obj file. If the model is triangluated and you export to Valve220 it should work flawlessly.

Mother of god...

Repo Is Public Now

#56 posted by khreathor on 2015/10/01 21:39:34

I made repo public! Sorry for inconvenience! :)

#57 posted by necros on 2015/10/02 02:55:49

ah mah gahd, this is awesome you guys!

#58 posted by Lunaran on 2015/10/02 05:28:10

There's a fewest-planes wrapping algorithm floating around somewhere that would be ideal for exporting weird shapes like dragon heads in an optimum minimum number of convex brushes ...

Oh My Goodness!

#59 posted by Skiffy on 2015/10/02 16:54:00

Just out of curiosity is it possible to use valve220 map formats to make quake1 and 2 maps for the compilers?

#60 posted by adib on 2015/10/02 18:20:15

Yes, modern Quake compilers can process Valve220.

#61 posted by Lunaran on 2015/10/03 04:17:36

This has probably been asked a dillion times, but does the .bsp format support arbitrary texture alignment or is it as limited as .map and you need .bsp2?

Final .BSP Dont Care

#62 posted by Skiffy on 2015/10/03 04:40:27

.bsp ultimately does not give a crap since its turned into pure polygons with uv coordinates. .map brushes and the way the data is stored was purely out of speeding things up during those dark days when unwrapping and texture alignment was a pain in the butt.

In fact you could in theory edit the texture mapping after a compile and replace it.

#63 posted by Spike on 2015/10/03 06:49:20

its only quake3 that has actual xyz+st+lmst+rgb coords. the earlier versions all calculate everything based upon the xyz and their texinfo's texture planes (basically like valve220 with the scale+rotation things baked in to the plane itself).

this means the (software) renderer can generate the s+t coords dynamically after clipping, instead of having to clip those s+t coords to the screen too and getting extra imprecision+inefficiencies from doing so.

#64 posted by JneeraZ on 2015/10/03 11:37:50

Wait, really? So ... potentially I could, say, model an entire level and then use whatever eric is cooking up to turn it into an actual map? With custom UVs everywhere?

Don't tell me that's true ..I'll never sleep again...

bsp.exe will be having a right old party, but it sounds like it :}
