Run it through PoseRay and fix your normals.

hi

Thnx for the quick rep..I downloaded poseray a few moments ago..it seems that it does not convert into obj files..

I was wondering whats wrong with my file up there?

Thnx!

Have you tried searching for Poseray in these forums? One of the many posts might help answer your question.

You can see missing sides in your original image, so it most definately is a problem with your geometry.

If you are looking for a good 3D package, I recommend Blender. It will output wavefront obj files, which can be loaded into Terragen 2 directly. PoseRay definitely helps. I have tried Google's Sketch Up, I think Blender will read these files.

From the manual:
OBJ Output Tab:
PoseRay can save a Wavefront OBJ file and its materials containing all the modifications done in PoseRay. Saving the scene as an OBJ file from PoseRay will save all the scene information such as lights and camera as well as materials. Reloading the OBJ file will restore the entire scene if desired.

Misc. options:
Save normals will save the normals into the OBJ file. Some programs require this information for properly displaying the model.
Save texture coordinates (UV) will save the texture coordinates into the OBJ file. These are needed if the model is texture mapped.
Fix material and groups names. For example a material called skin:2 will be renamed skin_2. This is useful if the importing program has problems with the original naming.
Export camera as a mesh. This will export the camera as a mesh in case you want to use it for realigning the camera of the importing program as it was in PoseRay.
Export options (after pressing save):
Export Name Prefix is the prefix for all the output files. For a prefix name PoseRay will create two files:
name.OBJ: contains the modified Wavefront model.
name.mtl: contains the materials used in the OBJ file. All the material properties will be saved including map names and POV-Ray textures. Specular will be saved as an exponent from 4 to 4096.
Overwrite files (except render) will overwrite all exported files
Include file paths to image maps should be enabled if the maps are located in a different directory than the one used for the POV-Ray files.
Copy all maps to the same directory will make copies of all maps used by the scene and place them in the same directory where the POV files will be saved. Note that when this option is enabled the paths to the images are not included in the output files.
Fix map names removes all non alphanumeric characters from the map filenames.
Fix map resolution to [ ]. This will resize the maps as they are copied. Largest dimension will have this resolution. All resized maps are converted to JPEG format.

It looks like google sketchup makes their models aout of 2d planes instead of 3d solids,
this often causes the 2d planes to apear backwards then converting to another format,
then a planes is backwards it becomes transparent, so look for an import or export option
that deals with convering  normals to positive or non- negitive vauues or somthing like that.

post the model in you can
we might be able to see what that issue is...
obj is a really simple format...




that said - I don't know why people use SketchUp, it's possibly the worst application you can use if you intend to actually use the models for anything other than conceptual design work...and to have the audacity to charge $495...unreal...
there are a ton of better, free applications, blender has been mentioned, Houdini Apprentice, lots of others...

That's because your sketch up program sucks! But that wasn't the question...
Title: Re: 3d modeling
Post by: Henry Blewer on August 14, 2009, 07:03:25 pm
Sketch up was not really design to do more than work with Google World, a gimmick. But for Google it works well. You can take the image maps from the building and put them into a 'real' 3D modeling program. They become backdrop images, Then You can build you objects. Sketch Up may be able to give your objects a floor plan which would make things even easier.

As far as your images 'sucking'. That's not really true. It's only lack of experience, and practice makes perfect. There is a lot to learn, you'll get there.

Don't give up on it so easily! The images you produced at the start of the thread are really good starts. Even if you use it only to visualize what you have in mind, it has been useful. Tools (software) have their own uses, but a screw driver can also be used as a chisel. (not recommended)
My first renders were really bad. Many will say they still are. I keep trying.

Edit: I just looked at your image. Try turning on double sided polygons. Faces are not showing up. There may be a 'calculate normals outside' function. That may help.

I agree with njeneb,
Don't give up! If you had fun with the model, keep at it. As someone pointed out, Blender is free.
I must warn you though, it's fun, and crazy at the same time. Making a model that blends into a TG2 environment is one of the most difficult things you'll ever do. You can spend hundreds of hours working on a model, just to have it overlooked by your peers, but that shouldn't keep you from working at it if you enjoy the challenge! It's up to you. I've been working on a couple of Walkers and neither is up to snuff, for TG2. But that doesn't stop me..
You may think this AT-PT-Walker WIP looks nice. Blending it to TG2 is a 2'nd and 3'd project in itself. ;) Just so you know, and everyone else that downloads all the free models, and pay for views.. A lot of work, went into and behind, your hours of TG2, placement..
Sorry for the rattle.. :)

this link is an improved ruby script for object export from sketchup, make sure you download the objexporter.rb and not the x exporter

Mandrake, if you made that Walker, you're a very good modeler.

Oh did this last night to take a break from the walker, if you want it.

If your asking me that question. No, it's C4D.

Here is the link. It's free ware 3D modeling and rendering, plus image compositing, physics, bullet solvers, and game engine; plus. It is very powerful by any standard, but considering it's free, nothing else beats it. (except Terragen 2!)

And you can do Pro work with Blender, I used this as a reference when I built my Eagle
This was done with Blender.

I liked Lightwave better, but can't afford it now. Blender integrated with YafRay has been very good to me. I still have difficulty doing simple things with Blender, the cool stuff is buried currently. But the upcoming release should be more intuitive. Lots of Lightwavers use Blender for Fluid simulation.

in order to test it I downloaded and installed v7.0.10247 (the free version)
it works fine in that...

I have no experience of sketchup,  Because I WILL NOT install any of Google's advertising gateways (Profducts), on my PCs.   Try running your model through PoseRay again but make sure that you force triangulation. Terragen has become ultra sensitive since version 2.x. to anything but triangles.
