Render Sript

[Diego Ruiz]

Hi everyone, I'm new in the group and I'm learning about python for render, I'm using Maya 2014 but I have a problem, when I call the .py file, Maya tells this: 

# Attempting to send notification email

# Error: line 0: IOError: file D:\3D\jesusbuenahora\scripts\notification.py line 32: 2 # 

I check it out many times but always appears taht message, I don't know what to do, does somebody can help me please?, Thanks!!

in line 32 check if renderpath exist, generally IOError is when the file doesn't exist, if your scene is not yet rendered anything then likely that file doesn't exist

Hi Diego, and welcome to the group.

Unfortunately Maya isn't being very nice in telling you a helpful traceback message. But most likely your problem is that either the renderPath does not yet exist, or is inaccessible. Try doing this first:

if not os.path.isfile(renderPath):

    print "Does not exist!", renderPath

cmds.renderSettings() returns a string list. But you passed it directly to open(renderPath, ‘rb’) where open() expects a string (path) as its first argument.

You need to be more specific on which file you are trying to open. Looking at the example code on renderSettings(), the list it returns could contain empty strings in the list depending on which arguments you give, so you may have to perform further validation before calling open() as well.

He uses the first instead of the returned list:

renderPath = cmds.renderSettings(fin=True, fp=True)[0]

The problem is that he isn't checking if it actually exists before trying to open it.

Well there are no ways around the fact that trying to open a file that does not exist will produce an error. Have you tried checking and printing if the file does not exist? You should also return from the function after you report the error.

Thanks guys, like I said I'm new learning this, 

The line of code that you give me:

if not os.path.isfile(renderPath):

    print "Does not exist!", renderPath

is all right?, when I introduce the code in the .py, in script editor of maya gives this message:

# Error: line 0: IndentationError: file <maya console> line 1: unindent does not match any outer indentation level # 

I've rendericed the image therefore the images exists, I see it in the images folder from my project of maya

thanks for help

Well that error just means what you have pasted in has inconsistent whitespace (which is important to python syntax). But ultimately your script does have to check if the file exists. If you can get this snippet added to your code and you see it print that it doesn't exist, before crashing, then that would explain it. 

Otherwise, the file exists but there is some other issue with your being able to read it, such as permissions.
