hello
i tried to render animation with this code but i got error

    def renderAnimation(self):
        inPath = self.anim_input.text().toAscii().data()
        mxsList = getFilesFromPath(inPath, 'mxs')

        scene = Cmaxwell(mwcallback)
        for mxs in mxsList:
            scene.readMXS(os.path.join(inPath, mxs))
            #ok = scene.writeMXS(os.path.join(outPath, mxs))
            #outPath = self.edit_input_file.text().toAscii().data()
            outMxi = self.edit_mxi_file.text().toAscii().data()
            #outMxs = self.edit_mxs_file.text().toAscii().data()
            outImg = self.edit_img_file.text().toAscii().data()
            #outDen = self.edit_den_file.text().toAscii().data()
            choice = os.path.join(inPath, mxs)
            
            parameters = []

            parameters.append('-mxs:' + choice);

            runMaxwell(parameters);
            return 1;
            #scene.freeScene()

You found another bug! pymaxwell module expects Maxwell 3 installed instead of Maxwell 4.

To workaround this, you can define your own "runMaxwell" function like this, is quite simple:

Code: Select all

def myRunMaxwell( parameters ):
	if sys.platform == 'win32' or sys.platform == 'linux2':
		try:
			mwroot = os.environ['MAXWELL4_ROOT'];
		except:
			print('MAXWELL4_ROOT environment variable not found!');

	if sys.platform == 'win32':
		parameters.insert(0,mwroot+'/maxwell.exe');
	elif sys.platform == 'linux2':
		parameters.insert(0,mwroot+'/maxwell');
	elif sys.platform == 'darwin':
		parameters.insert(0,'/Applications/Maxwell Render 4/maxwell.app/Contents/MacOS/maxwell');
	else:
		error;

	subprocess.call(parameters);

Why it work before with camera views ?

I detect some possible bugs:

    def renderAnimation(self):

            self.myRunMaxwell(parameters); # this call must include the parameters as input
            
            ...


    def myRunMaxwell(self,parameters): # since you defined myRunMaxwell inside a class, you must have "self" as the first input parameter

this one give me error : self.myRunMaxwell(parameters)

the second : no error, no render
is the code right ?
the code of render cameras views work fine

the render for single scene work without errors

i tried again with single scene and i got this error inpycharm :

scene.setRenderParameter('DO NOT SAVE MXI FILE', self.anim_mxi.isChecked()==False and 1)
scene.setRenderParameter('DO NOT SAVE IMAGE FILE', self.anim_img.isChecked()==False and 1)

it work fine now ***.isChecked()==False

I think I didn't explained myself in my last post!

I comment between line codes:

Code: Select all

from pymaxwell import *
import os

def myRunMaxwell(parameters):
        # parameters is an input value, you MUST call myRunMaxwell(...) passing the "parameters" as input.
        if sys.platform == 'win32':
            try:
                mwroot = os.environ['MAXWELL4_ROOT'];
            except:
                print('MAXWELL4_ROOT environment variable not found!');

        if sys.platform == 'win32':
            parameters.insert(0, mwroot + '/maxwell.exe');

            error;

        subprocess.call(parameters); 

def run_maxwell_render(inPath,outFolder):

        mxsList = getFilesFromPath(inPath, 'mxs')

        for mxs in mxsList:
            scene = Cmaxwell(mwcallback)
            choice = os.path.join(inPath, mxs)
            scene.readMXS(choice)
            print choice

            #choice = ok = scene.writeMXS(os.path.join(outFolder, mxs))

            parameters = []

            parameters.append('-mxs:' + choice);
            parameters.append('-nowait');
            parameters.append('-nogui');
            parameters.append('-o:' + outFolder + 'a.jpg');
            parameters.append('-mxi:' + outFolder + 'a.mxi');
            parameters.append('-time:10');
            parameters.append('-sl:5');
            parameters.append('-res:300x200');
            
            
            # this one calls the pymaxwell "runMaxwell", it only works for Maxwell 3 so forget it for now (it will be fixed in the next release)
            #runMaxwell(parameters);
            
            
            # this call is wrong, it will return the function memory address, so it won't fail and it won't do anything!
            # you must call it this way:   myRunMaxwell(parameters);
            myRunMaxwell;
            
            
        #return 1;
        scene.freeScene()

if __name__ == "__main__":
	inPath = 'c:/input/anim/'
	outFolder = 'c:/intest'
	run_maxwell_render(inPath,outFolder)
