[TERRAIN] Wrong Blending/Flickering Texture of Feature

Hello Civ4 modders,

I had a problem with the attached 'nebular feature'. Nearby unexplored plots and in the fog of war, the textures looks totally wrong. Does anybody had an idea how I can fix this?

Regards Ramk

Code:

    <FeatureArtInfo>
      <Type>ART_DEF_FEATURE_NEBEL</Type>
      <bAnimated>1</bAnimated>
      <bRiverArt>0</bRiverArt>
      <TileArtType>TILE_ART_TYPE_NONE</TileArtType>
      <LightType>LIGHT_TYPE_SUN</LightType>
      <fScale>0.8</fScale>
      <fInterfaceScale>1.0</fInterfaceScale>
      <Button>Art/Interface/Buttons/TerrainFeatures/button_nebel.dds</Button>
      <FeatureVariety>
        <FeatureArtPieces>
          <FeatureArtPiece>
            <ModelFile>Art/Effects/Blite/Blite5.nif</ModelFile>
            <Connections></Connections>
          </FeatureArtPiece>
        </FeatureArtPieces>
        <FeatureDummyNodes/>
        <bGenerateRotations>0</bGenerateRotations>
        <VarietyButton>Art/Interface/Buttons/TerrainFeatures/button_nebel.dds</VarietyButton>
      </FeatureVariety>
    </FeatureArtInfo>

 

I compared it with an other feature and my new hypothesis is a wrong DDS-Texture format.
Edit: No, this seems not be right :-(

 

Sorry, I cannot help but curious of what it is supposed to do/represent?

 

It should represent an impassable plot with thick fog.

I switched on an other approach and it now looks like:

 

Woah, that is a mean looking ship. Where'd you get that bad boy?

 

I do not know what the origin source is, but it's part of PAE, see https://forums.civfanatics.com/forums/civ4-ancient-europe.494/
