Strange UV error
Hi. I am hoping any of you know what´s going on here. I am using 3dsmax 2012 and have a weird error. I have Unwrapped a 3d model, and up close in 3dsmax it looks correct. But when I zoom out in the editor I get lines at the edges of the model, it´s like the texture/UV moves/scales when I zoom out. Anyone have any ideas on… -
Re: Strange UV error
Thanks for all your answers, it helped a lot. The simplest way I found was to resize the 1024 atlas to 128 and then map it on the models. Then switch back to the 1024 atlas, and it looks good enough. -
Re: Strange UV error
There is nothing apart from re writing your own shaders and post processors to preserve that edge 100%. It's going to bleed, there's nothing you can do to stop that. What you need to do is make the bleed look good despite that. and you've been told how to do that already. If thoose solutions are 'incompatible' with what… -
Re: Strange UV error
Using tiling textures packed into one sheet has some unavoidable issues: http://udn.epicgames.com/Three/TerrainAdvancedTextures.html There will always be a slight bleed, even with a few tricks to pad those tiles by a couple of pixels. If you do crack it though - let me know! I spent a bit of time looking at this a while… -
Re: Strange UV error
Yeah, it's the mipmaps, nothing to do with clamp vs wrap. This is what you get when you try and tile a clamped (as opposed to wrapped) texture: -
Re: Strange UV error
MaliceSmash - actually you can do this in max, got to bitmap output in the material editor and clamp is there. Kurt Russell Fan Club - from what i remember if you are tiling a texture map , the clamp just means you dont get a 1 pixel black line around the texture. i am not tech savvy enough to exaplin it any further:) -
Re: Strange UV error
Yes, it´s the clamp function, I seek. -
Re: Strange UV error
yeah that 64 pixel paddding EQ mentioned also looks very cool Presentation wise:) if it's a tiled texture , is n't there an option to 'clamp' the texture so you don't get that 1 pixel bleed. long time since I have done this stuff with blitz 3d engine, can't find an option like this in max. -
Re: Strange UV error
No, I think you still misunderstand. Mip mapping is where your graphics card will choose lower resolution versions of your texture when a polygon is small (far away or at glancing angles). The lower resolution effectively blurs your texture. There are other things you can do as well as padding - make sure any texture… -
Re: Strange UV error
If you're sticking your tile borders at the halfway lines, then you're already minimising the effects of mipping as much as possible, without switching your texture filtering to point, instead of bilinear/trilinear/etc. The problem in this case is not so much the mipping (though it contributes), but the filtering.
