Also, for spritify you can use this tool: Just insert yours sprites and start the .bat-file what you need or make the new one.

Make this code, then it's not crop sprite at 128 pixels anymore. And it makes one sprite sheet with 8 columns.

Code: Select all

montage "Sprites/file*.png" -geometry +0+0 -tile 8x -background rgba(0,0,0,0) -quality 100% Sprite_x_8x.png
With 8 raws:

Code: Select all

montage "Sprites/file*.png" -geometry +0+0 -tile x8 -background rgba(0,0,0,0) -quality 100% Sprite_x_x8.png

If your sprites have too big alpha border, it can be cropped with this script:

Code: Select all

magick "Input/*.png" -background none ^
   ( -clone 0--1 -layers merge ^
   -set option:cropper "%%[@]" +delete ) ^
   -crop %%[cropper] +repage ^
   MIFF:- | magick montage MIFF:- -background none ^
   -tile 2x2 -geometry +0+0 Output\best_spritesheet_2x2.png
Examples, code from this forum, a lot of thanks to GeeMack.

Pros: You are cut all alpha from sprites, so your spritesheet will have much tiny dimensions. All sprites have same dimensions, no pixel with graphics will be deleted.
How to use: place your sprites to Input folder and start .bat-file.

For people having trouble when trying to generate the sprite sheet, specifically when blender can't find the "montage.exe" file, here's a fix I did.
I replaced line 121 in the spritify.py file with the full path + file name of the montage.exe that ImageMagick installed :

Code: Select all

"C:\Program Files\ImageMagick-7.0.8-Q16\montage.exe",
where it used to be

Code: Select all

"montage",
Idk for sure, but I think it has something to do with environment variables or something.

My problem now is that it's removing transparency from all the output images no matter what color I choose for the background... I've done a little research and found it might be a bug with montage.exe. Idk.

Don't forget this part:

Code: Select all

-background none

Use such code:

Code: Select all

magick "Input/*.png" -background none ^
   ( -clone 0--1 -layers merge ^
   -set option:cropper "481x337+328+315" +delete ) ^

   MIFF:- | magick montage MIFF:- -background none ^
   -tile 2x2 -geometry +0+0 Output\best_spritesheet_2x2.png
pause

And, for making icon 128x128 use this:

Code: Select all

magick "Input/*.png" -background none ^
   ( -clone 0--1 -layers merge ^
   -set option:cropper "%%[@]" +delete ) ^
   -crop %%[cropper] +repage ^
   MIFF:- | magick convert MIFF:- -background none ^
   -adaptive-resize 128x128 -gravity center -extent 128x128 best_icon_128b.png
pause
transparent background supported.

I hate bumping up very old threads, but my search through the forums hasn't been very good.

Blender recently had a major update to their UI, and I'm wondering if anything in this thread no longer applies (I noticed in the images it uses Blender Internal which doesn't exist anymore)

Great! here goes my bookmark. I'm a newbie at 3d modelling, but I will try my best and maybe create something worthwhile.

So, Blender has a number of things that are different/not working from this tutorial, but they're easy enough to get around.
Firstly, changing background to transparent in 2.8 has to be done something like
https://blender.stackexchange.com/quest ... d-in-eevee

Secondly, the shadow receiver plane doesn't work with the new default render engine, and I haven't figured that out yet.

Lastly, the spritify tool wasn't working for 2.8, so I updated it
https://github.com/jmattspartacus/blender_spritify

I'll make a separate forum post about updating it.

Can you adjust it to use this code? Here is a special cropping before the spritesheet.

Code: Select all

magick "Input/*.png" -background none ^
   ( -clone 0--1 -layers merge ^
   -set option:cropper "%%[@]" +delete ) ^
   -crop %%[cropper] +repage ^
   MIFF:- | magick montage MIFF:- -background none ^
   -tile 2x2 -geometry +0+0 Output\best_spritesheet_2x2.png

I'll look into this in a bit, currently working on finishing up texturing some models to render.

This guide was created for Blender 2.66a, but should apply to any other version (UI might hav....
Thank you so much, SkaceKachna! that was extremely useful guide.
in blender 2.8 with Eevee renderer it was a bit different, but still easy.
btw I've updated the script to work with blender 2.8

Download the updated script here.

What is the scale in Blender compared to the game? I will be importing models from SolidWorks using mm scale.

1 meter (or 1 unit) is 32 and 64 pixels for low and high resolutions. The tile size.

Set the camera to orthogonal mode, set the output resolution to 512x512 pixels, it will be the area size of 8x8 tiles for hr graphics.
