a little change : i save the same scene and use it
Code: Select all
from pymaxwell import *

def render_all_cameras(inFolder,inPath,outFolder):

  scene = Cmaxwell(mwcallback);
  scene.readMXS(inPath)
  cameraNames = scene.getCameraNames()
  for name in cameraNames:
    camera = scene.getCamera(name)
    camera.setActive()
    outPath = inPath
    ok = scene.writeMXS(outPath);


    parameters = []
    parameters.append('-mxs:'+inPath);
    parameters.append('-nowait');
    parameters.append('-nogui');
    parameters.append('-res:300x200');
    parameters.append('-s:6');
    parameters.append('-o:'+outFolder+'/m_%camera%.png');
    parameters.append('-mxi:'+outFolder+'/m_%camera%.mxi');
    parameters.append('-res:300x200');
    parameters.append('-time:10');
    runMaxwell(parameters)


if __name__ == "__main__":
   inFolder = 'input_folder'
   inPath = 'mxs.file'
   outFolder = 'output_folder'
   render_all_cameras(inFolder,inPath,outFolder);

in studio or with command line
when i add this macro (%camera%) to create mxs output the name don't change like image and mxi
is this a bug ?
Not sure macros work with mxs files. Will try to find out.

How to add and assign materials with python
i tried with : addmaterial ; set material without success
and all time if some lines are not aligned i got errors
The alignment is python mandatory. A thing that I hate, but python is like that.

For materials I do it like this:
Code: Select all
newMat = scene.createMaterial("tmpMaterial")
mainObj = scene.getObject("My Object")
mainObj.setMaterial(newMat)

if not newMat.read("c:/path/to/material.mxm"):
   print("ERROR: cannot open c:/path/to/material.mxm")
So, I first create a new material, assign it to the object, and then read a mxm on that material.

thanks Luis ; sometimes even the code is correct the i thinked it is incorret because of alignment
---
the code after many tries it work fine
newMat = scene.createMaterial('default')
mainObj = scene.getObject(planeName)
mainObj.setMaterial(newMat)
if not newMat.read(newM):
print ('ERROR: cannot open newM')

-----
newM = 'C:/Program Files/Next Limit/Maxwell Render 4/materials database/mxm files/default.mxm'

thanks Luis ; i create this code to add infinite plane to maxwell scenes with default material ; it's not big thing but can help and maybe someone make the script better
