I'm using a low resolution texture (128x64) from an old game as a background image to help me model but it gets blurry (or aliased I guess) which ruins everything.

I heard that one might need to increase the size of texture but if I do that then texture will get messed up and I want to keep all pixels of it in the same place without "JPGing" it.

Is it absolutely impossible to get sharp background image? Zooming doesn't help either. My version is 2.79

And the texture itself

  • $\begingroup$ the problem it self is that the raster image has a very low resolution. By resolution, it meas that are used less pixels to descriminate an entity like an object. As you zoom in, and as it is a raster image, Blender, or any other software wont be able to increase automatically the number of pixels by area. What you can do is vectorize the image in external software (like Inkscape). Inkscape can try to vectorize automatically or manually. Once you have your raster image vectorized, you can zoom in, and save with an higher quality jpg or png. Remember that the vector image wont give new info. $\endgroup$ – MCunha Sep 19 '17 at 17:19
  • $\begingroup$ @3pointedit Nah, disabling mipmaps did not help. Thanks anyways. $\endgroup$ – Mickety Sep 19 '17 at 17:57
  • $\begingroup$ @MCunha I didn't understand a word why Blender can't just put small textures as background images without messing it up but you did give me a great idea about vectoring the image in order to increase it's size without data loss. I guess I'll have to stick to this solution unless a better one suddenly appears. $\endgroup$ – Mickety Sep 19 '17 at 17:59
  • $\begingroup$ if you take irfranview and do the most easy method of scaling an image, you would keep the pixel blocks. $\endgroup$ – user3800527 Sep 20 '17 at 6:51
