Hi Guys, I have a script that changes my Emitter value in an Animation sequence from Zero to 500 watts.
It used to run fine, but now I get this error message:

Uncaught exception at <anonymous script, id=1437229225744>:1: SyntaxError: Parse error

Any idea what is going on?

Here's the script:

#============== CHANGE THESE VARIABLES AS REQUIRED ==============

mxs_dir = 'C:\Users\Carsten Quilitz\Desktop'
mat_name = 'Emitter'
watts_min = 0
watts_max = 500

#================= DON'T CHANGE ANYTHING ELSE =================

import os
import sys
from pymaxwell import *

mxs_dir = os.path.normpath(mxs_dir)
if not os.path.isdir(mxs_dir):
print('ERROR: input dir not found: %s' % mxs_dir)
sys.exit(1)

mxs_files = getFilesFromPath(mxs_dir, '.mxs')
if not len(mxs_files):
print('ERROR: no MXS files found: %s' % mxs_dir)
sys.exit(1)

mxs_files.sort()
incr = (watts_max - watts_min) / float(len(mxs_files))
watts = watts_min

def read_emitter(mxs_path):
mw = Cmaxwell(mwcallback)
if not mw.readMXS(mxs_path):
print('ERROR: Failed to read %s.' % mxs_path)
mw.freeScene()
return None,None,None
material = mw.getMaterial(mat_name)
if material.isNull():
print('ERROR: Failed to find "emitter" material in %s.' % mxs_path)
mw.freeScene()
return None,None,None
layer = material.getLayer(0)
if layer.isNull():
print('ERROR: Failed to find layer 0 for "emitter" material in %s.' % mxs_path)
mw.freeScene()
return None,None,None
emitter = layer.getEmitter()
if emitter.isNull():
print('ERROR: Failed to find emitter for layer 0 in %s.' % mxs_path)
mw.freeScene()
return None,None,None
pair,ok = emitter.getPair()
if not ok or emitter.isNull():
print('ERROR: Failed to get emitter pair for layer 0 in %s.' % mxs_path)
mw.freeScene()
return None,None,None
return mw,emitter,pair

for mxs_file in mxs_files:
mxs_path = os.path.join(mxs_dir, mxs_file)
mw,emitter,pair = read_emitter(mxs_path)
if not mw:
continue
pair.watts = watts
emitter.setPair(pair)
if not mw.writeMXS(mxs_path):
print('ERROR: failed to write %s' % mxs_path)
else:
print('OK: adjusted emitter to %s in %s.' % (watts, mxs_path))
mw.freeScene()
watts = watts + incr

THANKS!

Ok, I found that the line:

from pymaxwell import *

needs to be:

from pymaxwell4 import *

and the script does finally start running.

EXEPT! now it stops at:

NameError: name 'mxs_dir' is not defined

Any ideas what I have to change to get it working?

CHEERS Q!
Will there be a Maxwell Render 6 ?

Let's be realistic. What's left of NL is only milk[…]
