texture compression

[Air New Zealand]

Hey guys.

 

My google earth models texture has a really bad compression problem.

The thing is surtian parts of the model are fine.

It is also fine when you download it its only on the 3d layer.

Any suggestions?  

here are my models.

Hi Air New Zealand,

It may be due to the processing the model goes through for Google Earth. I was able to see some strange textures overlap on the surface of your model in GE.The cause was hidden in the file of ".kmz" format, but the processing your models go through for Google Earth revealed it. If you saved the original file of these models in ".skp" format, you should check them.This solution should be found there.In my experience, it was exchanging a strange texture in SketchUp's default color.

I did check all the hidden geo in sketchup is there anything specific I could try?

What do you mean by "exchanging a strange texture" 

[Shinchan]

A strange texture, "attched screenshot overlapping groups of geo"  was found in the lower part of your model  in GE. 

Did you save the the original file of this model in ".skp" format? Have you also checked the inside of your model in SketchUp?

[Air New Zealand]

Yeah I check the inside of the model and it has the default grey.

I do have the orignal .skp file  

I understand where you are coming from I have checked the normals as well as all the faces on the model.

your summary of z fighting is exactly what I came up with I just cant understand why the converting creates this issue. the only other thing it could be is how google earth breaks up the faces with a single 3k "UV Map"

I will attach the file so knock your self out

[Air New Zealand]

I have a feeling I know what it is there are for some strange reason some non 4 sided faces. I thing the upload and conversion have tried to convert the best It could but has applyed the texture wrong on the new face.

I will fix the model up and see if that changes anything in the next update

I'm also looking forward to a good result at the next '3D Buildings' layer update.

If there was a SketchUp file available for download, it would be much easier for more of us to look at it.
While in 3D View, it looks like you have Z Fighting which is cause when parallel faces are within 3 inches of each other (eg: if you drew 2x2 pickets for railing ... they would z fight or otherwise get deformed/distorted with the GE Compression).

It almost looks like there is already a model on that location and yours is overlapping it (i.e. 2 of the same model in one spot).

In any case, I would suggest going over your model in SU and I bet you will find that you have somehow created 2 faces for each side. In other words, I believe that you should be able to delete a face and you will find another right behind it. Check all the offending faces this way and/or check that there are no faces within 3 inches of other parallel faces.

If all else fails, please Share your SU file so we can take a look at it (preferably v7 version for me).

[SnowTiger]

You might have inadvertently Copied the entire model in that spot (i.e. made a copy but not moved it off location).
There definitely is Z fighting taking place.

If your model has been Grouped, try moving the Group. If only one object (building/model) moves, try Exploding the Group and then see if you can Move anything OR like I said previously, start deleting the offending faces to ensure there are no double faces.

I only looked at the Air New Zealand Hub building but I notice it's
only available for download as a Google Earth 4 model. Are you using
the most current version of SketchUp (v8) to do your modelling? If
not, you might want to update, revise and resubmit the model in the
most current SketchUp version and see if that makes any difference. I
didn't download and look at the model in v8, only in Google Earth, but
I see the Z-fighting going on on a number of faces.

Hi Air New Zealand,

This is probably caused by a "Very tiled texture". I see you are using a texture atlas for this model (I imported the kmz to SU8). This texture atlas is tiled a ton on one of the tiny faces on the front (see screenshots).

Since the tiles are very small, and the texture is also used throughout the model, they will be averaged when it goes through 3D layer compression.

Remove the very tiled texture on the face shown (and any other faces where it is very tiled) and it will be fine.

Let me know if you need a better explanation,

I went through all of the faces and replaced heaps of these faces with the repeated texture I obviously missed a few bu would this mess up the whole model.

Its just strange that some faces are fine and others aren't

I did export the model as a collada file from maya to sketchup I wonder if there was a conversion error that has a hidden thing that causes this

I will try just replacing the faces though with the proper texture
