MerlinX420,

- Ideally we want to move away from allowing GPL as an art license, because the GNU and FSF folks don't recommend using GPL for art

- In Reality we can't because the behemoths of free games (e.g. Wesnoth) are still under the GPL mandate.

Hard to choose what to do.  Hopefully new projects don't do GPL content mandates so we can move past this eventually.

This is a weekly discussion/argument in our IRC channel. 

raptorus,

Thanks!

Yes, I coded this alone.  I started in January 2010, so not even 1 year so far.

Here's how I render those sprites:

1. First I animate the model facing one direction.  In Blender all the animations are on one timeline.

2. Next, I have a Python script I wrote that I run inside Blender.  This renders each frame of the animation then rotates the scene 45 degrees.  It does this 8 times to get all 8 directions.  I run this in Blender 2.49, have not tried this yet in Blender 2.5

3. The result is lots of individual images.  I then use ImageMagick "montage" to combine them into one image.  Example: montage -background "transparent" -geometry 128x128 -tile 32x8 output.png

The Python script:

import Blender
from Blender import *
from Blender.Scene import Render
pi = 3.14159
deg45 = 45 * pi / 180
context = Scene.GetCurrent().getRenderingContext()
basePath = context.renderPath
for i in range(1,9):
    # objects without parents should be parented to RenderPlatform
    platform = Object.Get('RenderPlatform')
    platform.RotZ = platform.RotZ - deg45
    platform.setLocation(platform.getLocation()) # refreshes the child locations
    context.renderPath = basePath + str(i)
    context.renderAnim()
    Blender.Redraw()
context.renderPath = basePath

Love it! I've entered this into our "Halloween" art challenge.

The theremin really nails it!

Well done!

I'll probably make the "depleted" version darker so that I can, in my colorblindness, more quickly see the current levels.
