The problem is that it's looking for the textures, but either the file(s) or the directory doesn't exist
What you probably have to do is go to the directory of 'import_blb.py' as shown in your error message, open it with Notepad, and edit the file paths to where your Blockland directory is
def AddTex(Tex): # final command
if bpy.data.textures.find(Tex) == -1:
if Tex == 'PRINT':
path = os.path.expanduser('C:\\Program Files (x86)\\Steam\\steamapps\\common\\Blockland\\base\\data\\shapes\\spraycanLabel.png')
else:
path = os.path.expanduser('C:\\Program Files (x86)\\Steam\\steamapps\\common\\Blockland\\base\\data\\shapes\\brick'+Tex+'.png')
image = bpy.data.images.load(path)
text = bpy.data.textures.new(Tex, 'IMAGE')
text.image = image
text.image.use_fields = True
if Tex == 'SIDE':
text.extension = 'EXTEND'
return
If you don't have Blockland on Steam, then change both of the file paths to
C:\\Users\\USER_ACCOUNT_NAME\\Documents\\Blockland\\base\\data\\shapes\\spraycanLabel.png
and
C:\\Users\\USER_ACCOUNT_NAME\\Documents\\Blockland\\base\\data\\shapes\\brick'+Tex+'.png
If you're using Conservative's BLB importer as well, you'll have to do the same thing
