Flatiron

Hi all

I use Flatiron to automatic unwrap and bake buildings in my scene, but the UV map don’t seem to work right in Unity. It all look ok in Max after I collapsed it to mesh and hit render or in the viewport.

Any ideas what’s going wrong?

Thanks, Fillock

Hello!

A quick question.

If you collapse it, save it as a fbx/3ds/whatever, close 3DMax and open it again with 3DMax, the object saved before has the UV’s good?

Hi, looks to me like the UV’s are getting auto generated yet not applied or something here.

Would you be able to send the FBX and original Max file over to me a support@unity3d.com in order to let me take a look at your channels and help out

Thanks both!

I did export to 3ds, restarted max, imported it to Max again but without solving the problem. Hi Joe Robins, I Zip’t and sendt it, thanks.

As mention in the mail: After the Flatiron job is done it ads a FlatironModifier in the modiferer stack in Max, I don’t think it exports to Unity, but the geometry seems to keep the information when colapsed to Mesh, but the map channel 2 is no longer posebly to acces… dont know if thats relevant to the problem?

Ok so what Flatiron doing is generating the UV’s in an additional channel.

Unity’s shaders by default use UV mapping channel 1 for all diffuse textures, which in this instance isn’t how your mesh is set up.

I don’t have Flatiron installed as a plugin but if you collapse down the mesh, and look into the map channel info you can fix this.

please see the following two images that show a before and after of the mesh with a description of how to get things sorted :slight_smile:

Oh btw, you will find the Map Channel info dialog at the bottom of the Tools dropdown menu

in Unity3D - Inspector - SwapUVs - Apply

btw. is there any (cheaper) alternative with the same main functions like Flatiron?
I’m really thinking about purchasing, but it seems really expensive compared to other plugins.
