Some help with Nvidia .dds format and the mipster script.

Deadity

Hello members.

I am a newb in this forum. I tried to search for this topic but it hasn't been discussed extensively. I wonder if anyone knows about any tutorials on how to make your own mipmaps for the .dds format.

I want to make my own atlas texture, and I wanted to use my own mipmaps so that there will be less seam texture bleeding.

I ran into some trouble and was wondering if anyone could help me out.

I ran the mipster script in Photoshop. The original texture is 512x415 pixels (just testing) and after the script I got a 512 X 1024 pixel image. I tried to save it in the .dds format and got this error message:

Image width and height must be multiple of four

My image is clearly a multiple of four, but I tried to enlarge the image to 1024 X 1024 and I was able to save the image without any problems. This is clearly not the solution I was looking for, and I was wondering if anyone could shed some light on this problem.

I am using a 64 bit version of Photoshop.

EDIT:

I have found a solution to the problem. Apparently the Mipster script adds an extra row of pixels in the 64 bit version of Photoshop. The correct size for my example image should be 512 X 1023. I still wish that someone could point to a tutorial that explains how this script works and some best practices when working with mipmaps.

the way i think i solved it was to save the original image as a dds and let photoshop generate the mips first, then reopening it in photoshop (including mipmaps) and paste in my custom mips on the corresponding layers. resaving with custom mips worked while saving didn't. no clue why though.
