Actually I created my terrains exactly that way. When I tried DDS textures, I was creating the mipmap chain with the Ati Compressonator, I put the textures in the level folder and in MED I was setting them up as external textures.
But like with (internal) .tga textures only the first texture is rendered with mipmaps. In my terrains the first texture is usuall a gras texture.
I was making some screenshots.

This one shows the terrain with .tga textures (mipmaps created in MED):



This here shows another terrain with DDS texture. While the gras texture is rendered with mips, the roadtexture in the background doesn´t show the mips.



For comparison here are two other screenshots with the modified template code. The road and the rocks are blurred in the distance.





But anyway, if noone else has this problem it is maybe my videocard or something else in my configuration. But the strange thing is, that normally mipmaps do show up. It´s not an urgent issue for me (I´m just testing and developping my skills at the moment), but I wanted to inform you about this and if there´s an opportunity, maybe someone could have a look at this on a different system.

I am using A6 Pro 6.50.6. But I am experiencing the same problem:

Quote:

only the first terrain texture (the second skin) was using the mipmaps. The textures that are used for the red and green parts of the RGB map appeared too sharp (pixelig) in the distance.




I use .bmp as texture, I check the Mipmaps button checked in skin2, skin3 and skin4.

Does something change when you use 24 bit TGA instead? BMP is normally converted to 16 bit, which reduces the colors and could maybe give the impression that it's not mipmapped. If the problem also occurs with TGA, can you upload the terrain so that I can look into the problem? On my test terrain the mipmaps work well.

Hello!

I had this problem also with .tga textures. I made a little level with the terrain file, if you could look into this, it would be great. I also included DDS Textures, where I had the same problems.

I replaced all skins with 24 bit TGA but same. And I found the mirror of terrain is strange, it only show the 1st skin in terrain.

I also post my problem in another thread

Unfortunately I found another problem, that might be related.

For a tree I use two different DDS textures one for the leaves and one for the trunk.
When I store the textures separately (MED setting "external"), no mipmaps on my screen.
If I store the same DDS textures (DXT1 and DXT5) in the model file, they work.



The picture shows the tree model. The tree on the left side uses the DDS textures stored internally, the tree on the right side uses the same DDS files. The only difference is, they are now external.

The model on the right side - in comparison to the identical model on the left - is very pixelated, when the view is not close to the models.

Yes, this could be a related problem. I'll be away next week and am having a tight schedule until then, but I'll look into this problem after my return.

Not yet, but it's still on my schedule.
