  1. We are migrating the Unity Forums to Unity Discussions. On July 12, the Unity Forums will become read-only.

    Please, do not make any changes to your username or email addresses at id.unity.com during this transition time.

    It's still possible to reply to existing private message conversations during the migration, but any new replies you post will be missing after the main migration is complete. We'll do our best to migrate these messages in a follow-up step.

    On July 15, Unity Discussions will become read-only until July 18, when the new design and the migrated forum contents will go live.


    Read our full announcement for more information and let us know if you have any questions.

    So I was glancing at GLview and I saw that one of the two unsupported things for OpenGL 2.0 are texture_non_power_of_two. So when that is supported will we be able to bring in any texture size we want to unity if you add that support, because that would be realy nice. Jeff

    Problem is that only top of the line video cards today support it, so it won't be viable for games for a long time.

    And even then, non-pow-2 textures work somewhat slower than pow-2 ones; you can't DXT compress them and they have a bunch of other negative effects. So at least for a while realtime graphics will still be using pow-2 textures.

    Well at least you could offer to internally transform a non 2^x texture to one. So you would be free to just throw a texture in and let the tool take care of. No big deal, it's more comfort but can be handy if you deal a lot with non 2^x textures.

    We could do that, but we would rather educate our users, so they don't end up with a bunch of suboptimal games...

    It's a tradeoff, I guess. We do a some of these things for meshes, and we might do textures at some point as well....

    Hi Nicholas,

    you benefit at points where you take picture material you find somewhere and which is not thought as a texture from scratch or photowork for instance which you just can use and tryout before you have to make it a 2^x texture. At this point when trying out graphics i'm not after optimisations just after the effect so there you can spare time. Also not everytime you need the best performance, right?!

    I would say it's a plus if it would be there. No one must use it but it makes things more handy...

    If we make it just work, then people will use it all the time without knowing better. Having a Photoshop droplet that scales an image to 512x512 is not _that_ hard to do.

    I'm not overly religious (about this point, that is ;-), just feel we have better things to do. If it's for dev. speed, there are things that make a MUCH larger difference once you work on a real-sized project, and as features go, it's doubtful return on investment.

    I would agree that there are more important things to be done but i disagree that it won't be a time saver as from contract work i know that it's very helpful!

    I think this is a perfect use for an Automator workflow. I have a few in Finder that for instance convert to jpeg... scale to 512x512...

    edit: oh maybe this doesn't scale independently in both directions ;) Have to crop the images in some way pre or post scale. Or get some Photoshop automator plugin perhaps.

    Hi aarku,

    first starting an automator is a further step and hmm what should i say, for example take a project where the program reads in external data like textures so that the client still is able to change his content as he wants. Believe me there will be for 100% no matter how often you say it people who will use non 2^x textures and and and...

    /me postulates: It is more handy!

    By the way sw3d does it and believe me they didn't implement it for no reason.
