Leadwerks Obj Fixer

[Einlander]

Ever made a level in csg and exported it to obj? Well you probably found out that you end up with one massive mess of polygons. This tool fixes that. It will take a leadwerks exported mesh and fix it to something that is easier to handle.

 

What it does:

Separates all the objects into mesh groups.

 

What it doesn't do:

Anything with textures or uvmaps. Leadwerks doesn't export any of them

 

It was written in vb.net so it should run in wine if your on linux.

Very Cool.

 

I was thinking about UV map exporting to obj, and I think you can by exporting it as a vmf and using propper to convert it to an obj. I'll check it out tonight.

Let me know how that works. I would love to be able to export buildings from leadwerks.

My goal was to use propper but since it's a modified version of vbsp, it needs the Source Engine binaries to work and will not build a obj unless you have your textures as a vmt in a source project. It's a lot of work for a simple thing, but do-able.

 

Here's propper's source code. Maybe some one here can make it a standalone app?

I found a convoluted way to get it into a editor with the uv's in place. But you will have to add the textures back yourself.

 

You need 3 things:

Crafty : http://nemesis.thewavelength.net/index.php?p=45

Delgine : http://www.delgine.com/index.php?filename=product_deled

and a Delgine plugin: Map Importer http://www.delgine.com/plugins/viewPluginCategory.php?catid=39&catdesc=Importers

• First you make your map in Leadwerks and export it to vmf.
  
• Open it in Crafty and export it as Map
  
• Import it in Delgine and export it as obj.
  
• Import the Obj in your 3d editor.
  
  • Y is UP and Z is towards you
    

  [*]Scale all uv's to .1

  [*]Add your textures back in. It will look exactly how it does in Leadwerks.

This is a lot of work though.

Unless they are desperate, nobody is gonna want to do that. I was hoping I could just make a batch that converts the vmf to obj.

 

Really odd that editor's obj export doesn't export the uvs in the first place..

[Einlander]

The problem with vmf/maps are the uv's are not relative. they are absolute to the texture. so you need the texture to derive the uv's. There is probably some math to convert them without, but i have never seen it done.

This is a lot of work though.

Or just open in UU3D, perform a UV unwrap, select the faces of the object and assign them to a separate mesh group, and then save as FBX.

I could be wrong, but I was always under the impression the whole idea behind the OBJ export was for the user to have a layout/size reference for their real models in a modelling app that would replace the CSG in the LE scene.

[reepblue]

That was most likely the intended purpose, but I can think of a few cases in which an artist might want to bring a brush (or a set of them) into their model editor. Depends on what you're trying to do really.

[macklebee]

Maybe, but surely any actual modeling application can create the UV's without too much difficulty? Perhaps, if its really a feature people want then maybe ask for it in the Suggestion Box forum? But I don't think the World Editor was meant to become an actual modeling application - I mention this because I have seen a post complaining about the lack of UV mapping because they were using the LE Editor to create objects to export and to be converted to B3D that had to be for something else other than LE4. Do people think that LE4 is a replacement to 3DWS?

 

Edit- tryed out the obj fixer - works great. Create the obj asset, use the fixer, open in modeling app and create UV's for the individual meshes. Pretty straight forward.

Its alright as long as you never adjust the textures in leadwerks, or scale them or apply multiple texture's to a brush. Then it all falls apart.
