spell/skill icon grid layer?

[bongobeat]

thanks all for your answers

which is the correct format for the output file?
DXT3, DXT5?

[dxt3 or dxt5] I would say that it depends on the the alpha content of the image, but that in most cases DXT5 is the format to use.

(sorry if I am repeating stuff)

using GIMP -
1. Create new (use foreground colour fill)
2. Filters > Render > Patterns > Grid
3. Adjust line width and spacing to suit
4. Use Text Tool (change colour to white) to add layers of number
5. Merge down all text layers and you should be good to go

Or here is a link to imgur with the 3 atlases (1024x1024 items, 750x900 traits, 256x256 conditions)

Once in your icon atlas, select open as layer, then once the grid has been added, reverse laer order

thanks for the precisions


Akroma, no problem for the repeating things

I already downloaded your grid texture when I searched for this post, but I wanted to know exactly how to create the full texture (with icons I mean).
First by seeing your grid I was wondering if you have to put all icons "by hand", it seems weird for me and then I though there is something special to do with the GFX atlas toolkit. But ... no. In fact I wasn't sure why you made that grid.

Well, after all those explanations, I know, now, that you have to make your atlas "by hand".

Anyway, thanks again all for your help.

For icon atlases and GUI elements in general I recommend not using compression at all (save as uncompressed RGBA8). S3 compression artifacts look pretty bad on 2D images, especially on icon atlases since the icons will bleed into each other.

edit: For the same reasons you typically don't want to compress particle images. Of course you should still compress most of your textures for 3D materials.

I really wish Id know this sooner, thankyou for the info Minmay

To show a simple example of this effect
(Left - no compression, right - [dxt3 or dxt5])
