DS specs
Hi guys I had some questions about texturing a vehicle to Nintendo DS specs. Does the DS support reflections on car materials from an environment map or a reflection map? Would an artist just basically paint in some static highlights or reflections into the diffuse map for this type of texture. Some info that might help is… -
Re: DS specs
@Eric: Hmm... isn't additive blending required by the OpenGL-es spec? I didn't think it was even optional. Heck, the iPhone even supports GL_ARB_TEXTURE_ENV_DOT3. So it can do normal mapping but can't do a simple additive blend? That seems weird to me. At the least you can do two-pass additive with… -
Re: DS specs
Is there any particular reason your working texture is 1024^2? If you don't have, say, higher-spec assets using the 1024s, I'd suggest working at the final resolution, ie 256^2. Downsampling at this sort of resolution, as you've already noticed, leaves you with a blurry mess for the most part, requiring additional cleanup… -
Re: DS specs
DS hardware doesn't support additive blending. That means reflections will not be easy to do. Ask your programmers, because they will know more specifically what your engine offers. In general, I would not expect reflections. The DS can handle textures up to 1024x1024. Your limit is going to be memory, rather than texture… -
Re: DS specs
i would really recommend to work in 1:1 ratio and do detail work with the pencil tool. downsampling will always make your texture worse. you might try nearest neighbor option. you have to rework some details, but it stays as crisp as it can stay. ;) or the standard way, with downsampling, then a sharpen filter and use your… -
Re: DS specs
Polynurb just paint it at the actual res or don't go higher than 512 x512 if you plan on bringing it down. Photoshop also has an option to resample an image using bicubic sharper in the image size menu. I think the default is bicubic. You might as well and take a look at how all those options work to see how you like them… -
Re: DS specs
Hey guys thanks for the info and discussion. I am indeed working with 256x256 texture space for a single vehicle. I am losing detail in the down conversion when I start working with a 1024 to paint the textures. Wonder if there's anything I can do to retain some crispness to the texture when I down convert it to a 256x256.… -
Re: DS specs
I might try an unsharp mask filter on the large image before downsampling it. -
Re: DS specs
256*256 is enormous. You'll be severely limiting what you can have in your environment and elsewhere if you go using textures that large. 128*128 is generally workable for characters and vehicles and so-forth, though you're better to opt for lower than that if you can get away with it. Be as efficient as you possibly can… -
Re: DS specs
we here at shin'en have reflection mapping in our engine. it's a "hack" so you need your programmers to implement this as a feature. i wouldn't recommend thinking in higher then 256*256 texture sheets(=64k). you have to squeeze eveerything in your 512k budget, including fonts, hud, etc.. and if you use both screens for 3d…
