Cloud layer issue
Hello,

I am trying to build new clouds and im using textures which are compressed to DXT5 out of monochrome 8bit png.

I get those stripes across the horizon and i dont know why..
There are 2 of them across the hemisphere. I found out that i can avoid them by making BGRA8.. But the size of the texture is too big..

Is there a trick to this, or a solution other than the format?

Are the image dimensions a power of 2?

If not, can you send me the original PNG and created DXT GFX files so I can investigate?
Thank you

No, they are not the power of two, and i used the converter tool.
Tried with the power of two, and the stripe is gone, but the file got larger smile

Here they are so you can take a look..

Thanks.

Textures which will be wrapped (texture coordinates addressing mode) are recommended to be a power of 2 size (this is recommended for all textures used for 3d graphics)

I recommend using non-pow-2 sized images only for images used for 2d graphics (gui images, gui backgrounds, etc).
