problem with really blurry textures

Hi, I have never made a game of the size that I'm working on right now before, and I have ran in to some unexpected problems.

When I try to add textures to the game, it gets really blurry, it looks terrible. I have looked for an answer for a while now, but I just can't find anything that works. I have tried switching the texture mode to advanced, using different file formats (.jpg, .jpeg, .psd) and changing the export resolution, but I barely see any difference.

I think the problem might be that the object is to huge because I never have any problems with blurriness when I add textures to small objects (x2.56 y5.12), but when I try to add textures to the larger objects (x26 y15), it suddenly gets super blurry.

Is there anything I can do along the process to make the textures look better? Thanks a lot in advance!

TL;DR: adding textures to huge objects makes the textures blur out, is there anything I can do to make it look less like a nintendo64 game?

PS: I use gimp to make the textures

The source format has no effect at all, aside from the resolution. What matters are the import settings in Unity.

Thanks man, that explains why most of the things I did in gimp didn't seem to have any effect at all.

What import settings should I be using to make the image crisper? I use an orthographic camera, is there anything different I have to take into consideration because of that? Anything more I should know, I'm still really new to materials and textures.

 

You need to change the texture/atlas import settings.

1. Select your texture/atlas
2. In the drop down menu at the top go to advanced
3. Play around with turning mip mapping and and off (depending on your texture size), filter mode, ansio level and format.

Do that until you're happy with the level of compression and amount of filtering. Here are some links explaining ansiotropic filtering and mip mapping. Hope that helps.

EDIT: As to specific settings it depends on the kind of game you're making and what platform you're making it for.

 

Thanks CJO, playing around with the settings makes it better

but

Just tried to use a larger image, and everything seems crisper. I am trying to play around with the settings to make it seem even more crisp. The only problem I have now is that the image seems insanely large, it's I use a 2600x1500 image for a 2.6x1.5 plane, is this really overkill or should it be like that (sorry for noob question, never had to deal with stuff like this before...)?

 

That's pretty large. How close are you zooming in on these objects?

For most cases, your in-game texture width and height should be a power of 2. (i.e. 256, 512, 1024, 2048).

 

I use orthographic camera and the size (zoom) is set to 4, what size should I use?

Here is a screenshot of the (untextured) game with measurements (x)x(y):

The measurements are how large the actual object is, not how much is showing on the screen

Edit: I have scaled the texture to 1024x1024 because 512x512 made it visibly blurrier. Is this still to large?

 

Having the same problem with having to meddle with a lot of settings just to import a clear image. All I am trying to get the image onto is a plane. Resizing camera, resizing plane, changing camera from perspective to orthographic, changing advanced settings for the texture import, turning off compression, toggling mip map. All not producing a clear image. Unable to find documentation on a way to import textures and get it right. Wish there was a reasonable explanation.

 

Just throwing this out there, but are you guys tiling your textures? have you modified the UVs on the model or is it one texture stretched across a large plane?

 

I was able to fix it by going into the Atlas texture made by NGUI and unchecking the option of "Generate Mip Maps"
