Well, why not make high res textures. For example, rather than 256 x 256 textures, use 512 x 512. Or make sure you aren't viewing at an angle, or too close, etc;

Omega is right. If you have a building ten feet tall (in Glest scale) and it's only 10 pixels tall on the texture, you'll have foot tall blocks of color. Obviously glest and blender can't add things that aren't in the texture. I'm assuming you're using blender of course.

My recommendation would be to
1. use a higher resolution texture as omega suggested (change the numbers when you're going to run the "Export UV" script) and
2. rescale portions of the UV that are less important to give more space (and thus more pixels - meaning more detail can fit there) to the more visible sections.

For #2, if you didn't know you can press "S" to scale the portions of the UV you have selected - just like in the 3D windows. Additionally you can then press "X" or "Y" to limit the scaling to either axis (X is left-right and Y is up-down). You can also press "M" to mirror the selection, in case it fits or lines up better flipped around. And of course, "R" allows you to rotate it.

So for instance, if you had a tank, you could make the portions of the UV that include the turret (which is seen more) larger on the UV grid. Obviously you'll probably need to shrink other portions to make everything fit on one texture, so something else will have less detail on it.

If you've got it in Glest, can we get a screenshot? Maybe seeing it might help us get a better idea. Also a picture of the texture as well would be useful.

Honestly it doesn't look bad in the image. It just looks textured. Keep in mind that, even when zoomed up closer in Glest, the game will be smoothing the image to some degree. To test how it'll look, export it and pull it up in the g3d viewer.

Out of curiosity, is that the correct picture? I just now noticed that you said "building" but the image posted looks like a sword.

Even if it is pixelated (I'm not seeing it, but I'll take your word for it) it should still look fine in Glest since the camera is zoomed pretty far out.  For alpha, if you're modifying your texture in GIMP, you can select the part you want to make into alpha, then click "colors" > "color to alpha", and then mess with the settings until you've got it the way you want, then apply it.  There's a little preview window that should show you what you're working with.  The part with the checkerboard pattern is the alpha.  It might take a little practice to get it looking the way you want it to, but just experiment around with it and you should figure it out.  After making the alpha, I generally use a bucket fill with opacity of .25 and a black color, so it makes the color less bright.  That's just my preference, though.

I'm confused... the model is a person but the texture is just a sword?  Anyway, here's what I got:



What you might be doing wrong is that your texture is a jpg file.  For Glest, textures have to be uncompressed tga.  You can convert the file by opening it in GIMP and saving it as a tga.  When it asks if you want RLE compression, make sure to leave the check box empty and the origin at the bottom left.  Also, the texture has to be in the same folder as the g3d in order for it to work.  I have no idea about 3ds, but for Blender you have to follow this guide https://docs.megaglest.org/Texture_material for applying the material, so I'm guessing it's something similar?  Also, make sure that all your objects are selected when you export, or you'll be exporting a totally blank file!

Yea, that sounds like an export problem, as well as the texture being the wrong format (but I think it would error out of the program if it had exported it at all). Perhaps the .jpg is causing the export issues?

Hmm... I think you're right about that.  Since the g3d is opening properly, but nothing is showing up, it sounds like you're just neglecting to select the objects before you export.  The script only exports what you have selected, so you're exporting nothing.

When all else fails, ask strange, unusual, or obvious questions.

What just came to my mind is "Is the texture 100% alpha transparent?

ok I took a look at it too.

1. you exported three different objcets in your .obj file.
 - A man ( without any texture but with fragments of a glest man UV mapping )
 - A simple block ( don't know what it should be, but it had no texture or UV mapping )
 - A sword with UV mapping but with a material, but both material and uv mapping have no texture!?!

and as someone said before a jpg as texture which is not supported by glest. ( only uncompressed tgas )

It's there...


it's just to small to see...


I had to bump that all the way up to 1 to get the image above...

To avoid exporting everything from the scene, use 'Export Selected...' rather than 'Export...'

Cheers.
