Source VTF Mipmap Filter

Does anyone know of a definitive guide to the various VTF mipmap filters available? The Wiki doesn't provide much insight at all. Through trial and error I found gaussian effective for busy textures but I'd like a reference to take out some of the guess work. Poor mipmapping is a fairly common oversight and can really degrade the quality of a texture.

Nem's photoshop plugin should be the answer to all your problems

I'm using Nems. I'm after info pertaining to which mipmap filter is best for different occassions. There's a shitload of different filters available, a reference would be handy instead of trial and error.

I just choose "generic texture" or "generic texture with alpha" as a preset. You don't need to fiddle with mipmap filters as far as I know (or just use "soft sharpen")

That is what I do 99% of the time (and I'm sure that's all most people do too). I've found that the presets aren't always the best though, particularly for something like highly repetitive tiles. When I have some spare time I'll take some ingame texture shots of the same texture using the different types of mipmaps.

Wunderboy was kind enough to produce this series of images comparing the different mipmap filters. As you can see the mipmap filter can have a dramatic effect on a texture at different ranges which is why box (Nem's default) doesn't always cut it. Definately worthwhile utilising different filters in some circumstances.

*edit: sorry, the sharpen filters comparison was broken.

That stuff is completely different Minos, texture compression, sharpen and mipmap filters are all unique filters. Nem's presets do a fine job selecting the compression type appropriate for different materials. I think it's worthwhile playing around with mipmaps and sharpen filters when the default results are poor though.

I don't allow hot-linking on my site Go to the original article on Texturehub instead.
