modeling with sketchup

[Shelltoe]

couldn't upload it here for some reason. it's a zip with a 800cmx800cm cube exported from c4d without root node as 2010.0 ascii fbx and a converted to 2013.3 ascii.

and just made sure both import nicely for me

 

[thomthom]

Excellent! Thank you very much!

The crash at game exit which I'm seeing seems to be related to the texture for the asset. When I removed the texture the game did not crash upon exit.
Originally my test texture (1024x2014) was a PNG. I thought it might be something with the format and converted it to JPEG. But still I get a crash.

Anyone got a sample texture that works for them?

(Oh, and that FBX cube - I diffed it to a similar cube from SketchUp and I see that SU inject two levels of nodes. CS seem to accept one extra level though.)

 

[Shelltoe]

1024x2014?? 1024x1024 typo?

here some 256x256 maps i used

the cube was actually done in sketuchup and exported as fbx. guess its the converter doing things different

Indeed! Fat fingers towards the end of the day...

Tried your texture - I still get a Stopped Working message upon exit. That's with my own FBX and textures, but also with that 800x800cm FBX and this smaller 256x256 texture map.

Now - it only happens during Exit - so it's not a show stopper. And I'm not sure if I see this message because I have Visual Studio installed and normal users might not see anything. Though the programmer in me is not liking this.

 

[Shelltoe]

as a programmer check your logs

i'll check the cube with my texture. i'm on mac os x though and probably won't be able to boot windows today.

EDIT: No Error in Unity Debug Console or System logs. besides telling me intel hd 4600 isn't exactly a gaming gpu

 

[thomthom]

Yea - was looking for those. Haven't located them yet.

But - I did find this thread: http://steamcommunity.com/app/255710/discussions/0/610574827763707979/#c611702631234632142
Seems like I'm not alone and it's a known issue with workaround - which seemed to work for me.

So that's good - I was afraid it was the FBX assets that corrupted something.

 

[Mr Maison]

It happens to me all the time especially when quitting straight to desktop. I just ignore it for now as it doesn't seem to do any damage. But thanks for that thread. I missed that info.

ThomThom you are a godsend to us Sketchup users for this game. Seems your script will make the Sketchup route the easiest and quickest of all 3D SW options if it works as intended.

Well, since the FBX exporter in SketchUp is Pro it somewhat limits the users. I'd think a good number of modders are Make users. I wonder if there are FBX console utilities out there - where one could then as a workaround export to collada and then convert to FBX. I dunno - that's one for later.

as there are no collada export options in SU you'll want to scale it during or before conversion

EDIT:
- export from SU to collada
- run FBXCONVERTER collada_file fbx_file /v /l /-e /f201300 /ascii
the converter seems to create a "take" but CSL shouldn't care about it

still requires 2.54 ingame scale as all floatpoints are in inch and CSL seemingly does not care about the colladascale

<unit meter="0.0254000" name="inch" />

<float_array id="ID8" count="174">157.4803150 157.4803150 0.0000000 -157.4803150 -157.4803150 0.0000000 ....

it doesn't seem to care about hardly anything besides the float_arrays

You mean unit options? There's a bunch of other options available:

And it's the only (I think) exporter which have exposed the options to the API:
http://www.sketchup.com/intl/en/developer/docs/ourdoc/model#export

Not sure how the collada format is in terms of units - maybe it's all world units... maybe that's why we don't have the unit options for this format. Need to look into that.

Excellent! That's great!

This is all looking very promising.

Yeah...you're right. You think Autodesk FBX converter would change anything if users exported via dae or obj? That may be make users best hope for now.

yeah unit option was available with version 7. 8 removed it (tried v7 but didn't help)

as far as i can tell CSL doesn't care about anything but the actual point arrays. you can remove almost everything inside the fbx and CSL will load the file.
the geometry float array has to be scaled x2.54 and you have to do some matrix calc to rotate them
there is a fbx sdk which might help.

everything seems to import nicely if you put ingame scale to 2.54 and "rotate X" 3 times though

 

[thomthom]

I cobbled together a prototype export-patcher: https://github.com/thomthom/cities-skylines-sketchup-tools/releases/tag/0.1.0
It will try to patch the exported FBX to remove the extra nodes in the hierarchy - as well as automatically set the needed export options.

Require SketchUp Pro 2014 or newer, Window only - for now. Once tested that it appear to work ok I'll try to adjust it for wider compatibility. The lack of OSX compatibility is just that I haven't had time to dig up my mac and find where the preferences are yet. It will be done later.

Please note that this is just a test version for now - it might not succeed. If you find issues then please report them in the GitHub repository: https://github.com/thomthom/cities-skylines-sketchup-tools/issues

Once it seem to be stable I'll release it officially on Extension Warehouse.

 

[Mr Maison]

ThomThom it worked on my end except for some minor texture issues that I'm not sure is me or the plugin. Using Sketchup2015 Pro. If I was on that side of the pond I would buy you 2 beers. Reporting in Github.........

 

[thomthom]

Thanks for testing.

The shift of texture color sounds like the color variation feature:

 

[Shelltoe]

took a quick look at your code. would it be possible to rotate and scale the mesh inside sketchup before exporting to dae?

 

[thomthom]

Yes, one could apply scaling and rotation transformation on the mesh before invoking the exporter - then reset afterwards.

Been testing the extension with real models today and it seems to be working ok. I wrote up a summary for the exporter extension: http://www.thomthom.net/thoughts/2015/04/export-from-sketchup-to-cities-skylines/

I'll see to adding OSX compatibility next then start looking at other improvements.

 

[Shelltoe]

yeah exactly.

the OS X "registry" path you might be looking for should be "/Users/<user>/Library/Preferences/com.sketchup.SketchUp.2015.plist"

 

[thomthom]

Yes, I expected so. Just need to figure out the structure of the settings.
