Problem with textures with model on GoogleEarth

[zajj...@gmail.com]

Hi!
I have builded a model of museum. When i had puted it into the Google Earth its some textures started to dissapear - like a holes in walls and some started to flicker like  a triangles going out of the model range. When i had placed *.kmz file into Google Earth it gived error message like a: Warning:Vertex array in geometry triangles: Material2:46988 has more than 64k verticles. Attaching picture of error message and model.
 I was thinking that the problem is with my videocard, i  downloaded new drivers, but problem stays.
 Does anybody know where is the problem?

Dear zajjamai,

That's quite an impressive feat, defining every last brick, window
pane and whatnot in this museum (at least the front and back sides).
I can't imagine how long it took you to do it.

Unfortunately, all these details are simply way, way, WAY too much for
GE to process. There are limits to modelling for the 3d layer
- the .skp file must be no more than 10 MB (this one is about 9.7 MB)
- there can't be more than 5,000 faces (your model info.jpg image
displays almost 15,000, and when I downloaded it, I got 42,000 faces
in the window, with over 119,000 edges!)
- the image textures can't be more than 2400 pixels in either
dimension, and you probably have way more textures (259) than you
actually need, with no more than 2 or 3 faces sharing the same texture

My advice - simplify, simplify, simplify. If you look up other
museums that reside in the 3d layer, you'll find that they don't need
sculpted surfaces where image textures will do the job. Find a good
photo of the front of this museum, or create a brick-surface tile
image rather than carving every last nook and cranny. If you have
Photoshop, you can create .png images that allow for see-through
spaces between metal bars and around weather vanes.

Hi zajjamai

A good resource to help guide you through how to structure your models for Google Earth can be found at:

http://sketchup.google.com/intl/en/yourworldin3d/modelwithsketchup.html

And in particular this PDF has some great pointers on getting a simplified model which still looks great:

Hope this helps.

Just some info about model comlexity in statistics:
Sketchup displays one face as one polygon in the statistics (equal whether it is a triangle or a circle), while classic 3d graphics only use triangles (like Google Earth). So a face with n edges consists in reality of n-2 triangles, displayed like one entity.
