Sketchup import formats?

Recommended Posts

  • Greetings,

    My son, Ben Kadie, would like to import a model Google 3D Warehouse to C4D. Using Sketchup Pro 7 (free for 7 hours of use), we've exported the model to many formats. But every import to C4D has problems, mostly with textures. For example:

    Ben would be grateful for help converting this model. Also, we'd both love to know what's going wrong and if anything can help in the future.

    The model in all the different formats is available as a 50 meg zip file from mansion.zip

    Thanks,

    Carl & Ben

    Have you tried exporting in Obj format? Then in C4D you can use the free "Riptide" plugin to import the model and textures.

    Hope this helps.

    Try Collada. I reimported your model into Sketchup then re-exported as a dae file and apart from a couple of reversed faces it worked OK.

    However, check the following. Before exporting, explode the group. Then go to Window -> Model Info -> Statistics and click purge unused. When you export to Collada, select options and untick export 2 sided faces, tick triangulate all faces, export texture maps. The rest should be unticked. When you import in to C4D, tick the Fix transparency box.

  • Steve,

    Thanks! The steps you suggested worked great. The result so far is attached. (Also, below are the notes I made for Ben and me for the future).

    One follow up question: What is the easiest way to fix the reversed faces? I can select with the Polygon tool and right click and see many options, but don't know which to use or if this is the best way.

    - Carl

    Notes on importing for Sketchup:

    IN SKETCHUP PRO 7

    Tools, Select, click the model

    Edit, Group (1 in model), Explode

    Window, Model Info, Statics, Purge Unused

    File, Export, 3D Model, export type: Collada File, Options (lower right hand corner)

    Only "Tranagulate All Faces" and "Export Texture Maps" should be ticked.

    Save

    IN CINEMA 4D

    Edit, Preferences, Import/Export, COLLADRA Import, Fix Transparency for incompaible files

    File, Open, the file

    To fix reversed normals, ????

    Function>Reverse Normals - if you have the reversed polygon(s) selected.

    Function>Align Normals - with the object selected in the OM but no polygons selected.

    Cinema's materials are double-sided by default, but if you apply a strong one-colour material to the entire mesh and set it to Back only, it may help in identifying where there are reversed normals.

    It's best to get the faces facing the right way in Sketchup before you start. They show blue if they are pointing the wrong way (turn on View-> Face Style -> Monochrome). You can try Orient faces or for individual faces Reverse Face but there is a plugin available that allows you to paint all the faces and they turn so that outward is towards the camera. It is called FrontFace and is a real timesaver. Unfortunately, because Sketchup is very forgiving about normals, a lot of the models on Google Warehouse suffer from this problem.

    Unfortunately, the texture will not be correct after the normals have been corrected, so the textures often need reapplying. It would be better for models intended for export if Sketchup didn't show the reversed face in the first place (i.e. it was invisible). It would be more obvious. I suppose beginners would get confused though with invisible walls etc.

  • Thanks to everyone for their help. We have a much better idea of what is going on, but sadly we still can't get it working. Like people have said, it really seems to have to do with normals, but nothing we try (including the Sketchup Greyscale/Facefront add in) seems to work for us.

    At this point Ben would be grateful to anyone who could convert the model for him. Here is the direct 3D Warehouse link:

    http://sketchup.google.com/3dwarehouse/details?mid=d0a49a3305229e565bc7a59f3ad92e52&prevstart=24

    Secondarily, we would love to figure out what we're doing wrong so we could do this for ourselves in the future.

    Thanks!

    - Carl

  • [Greetings, with help from Steve in this form and then xrok1 in the SketcupUcation forum, we now have a pretty good manual way to fix "inside out" Sketchup models. Thanks! - Carl]

    if you use the materials window eye dropper (sample paint) tool to click a face, then right click, texture>projected, then right click, reverse face, then left click to paint with sampled texture. for the next face hold down alt to sample and so on... you have to do this face by face but its the only way i can think of.Attachments
