White patches in TS2010

[hminky]

I am getting what appear to be white patches on my DEM:



They disappear when approached.

I am runnning TS2010 in Win7 64 witn a GTX260 video card in Direct X.

Also appear in TS2009

Trainz Surveyor in TS2009 and TS2010 has a peculiar way of rendering distant ground textures. What do these textures show when coming closer?

[hminky]

They disappear as you approach and if you spin new ones appear.

The patches appear in Driver also. The picture is from driver not surveyor.

They aren't permanent. The patches "flicker" on and off.

Do these patches always appear at the same spots with the same boundaries? How do the "proper" textures look there, viewed from close-by?

[hminky]

Looking at them more in other spots, the patches are transparent, I went to an area where clouds appeared.

Some show up in the same spots. Others areas go transparent at other times.

They appear in untextured and textured areas.

The textures appear normal in the textured areas.



OpenGL showing the spots transparent

I get more spots in OpenGL

What does "untextured" mean in your case? Is this the default Trainz grey/orange grid texture? Or the TransDEM ground textures? If the latter, it may have to do with the notorious "hardware texture compression" feature. Uninstall the TransDEM ground textures in Content Manager and reinstall them with this option explicitly disabled.

The untextured is the Trainz grey/orange grid and textured with the TS09-12 texture

Checked "texture compression" off and ran a Database Repair

Still show transparent areas. Textured with one of the TransDEM textures in the effected area and still shows tranparency

Made a new map as TRS/2006 and it doesn't have the blank spots.

It very much looks like the "hardware texture compression" issue. The problem may affect all kind of imported Trainz objects, not those of TransDEM alone. Other users have reported that a full de-installation of the objects in question and subsequent re-installation with the compression option disabled solved the problem. Some had to try a few times until they finally caught the offenders.

Keep in mind that a TransDEM route not only consists of the route itself, but also references the set of ground textures which you normally only install once.
