Xforce Keygen 32bits Or 64bits Version Maya 2011
Takeshi Krueger
I have searched around entire internet.1. i have 64bit 2014 maya installed, i had 32bit python installed at c:\python27.. as you know maya installs its own python and works with that, i want to change it and make maya work with my own python that is installed in c drive.
What i did?1. i did change the python, first unisntalled and and then installed 64bit version, i copied cv2.pyd to its site-packages and also installed matplotlib,scipy, pandas, numpy. my code in pycharm works just fine but maya gives error.2. i changed mayas python path environment but still maya is using its own installed python not pointing to mine.
Maya's version of Python (mayapy) is compiled with Visual Studio 2010, Python's 2.7.x standard distribution is compiled with VS2008, and the two aren't compatible. So packages you install via pip in your standard 64 bit Python install won't work with Maya if they have binary dependencies. (ex numpy, scipy, PIL, pandas, etc...)
On Windows, the plug-in is provided as a self-extracting installer. The plug-in is compatible with Windows Vista and above and with Maya 2012 and above (64-bit only). The installer will automatically detect which versions of Maya are present on the system and where they are located:
If you only want to extract the plug-in files without copying them to the Maya directories (e.g. for creating a package or some other form of customized deployment), you can change the autodetected path for the relevant Maya version to point to an empty directory (the directory must exist). You may want to uncheck "Uninstaller" in the Components page, since you probably don't need an uninstaller to be created in this case.
Keep in mind though that in order for Maxwell to work in batch render mode with the render.exe utility, the file maxwellRenderer.xml must be copied in the bin\rendererDesc subdirectory of the Maya install path. Maya does not look for renderer description files in standalone packages, so if you want to use that method of deployment you will need to make sure the XML file is copied separately to the correct path.
The install directory for a given Maya version is determined by looking at the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\Maya\VERSION\Setup\InstallPath (64-bit or native 32-bit) or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Autodesk\Maya\VERSION\Setup\InstallPath (32-bit Maya on 64-bit Windows). These keys are set by the Maya installer. If you ever move Maya to a different directory after installing it, make sure you update the corresponding keys, or the Maxwell plug-in installer will be unable to find the new path.
On OS X, the plug-in is provided as a self-installing package. The minimum supported OS X version is 10.11 and the minimum supported Maya version is 2012. The platform requirements are the same as for Maya itself: 64-bit Intel for Maya 2012 and above.
Each plug-in is provided with "replace_mxcommon_path.sh" file. This script must be used to set in the maxwell.so library the correct path to find libmxcommon.so (in Maxwell 4 root) and create in "/etc/profile.d" 2 files (maxwell4.sh and maxwell4.csh) that set the environment variable "MAXWELL4_ROOT". When you run the script the maya version must be specified as well as the path to the Maxwell 4 root:
Set the plug-in to autoload to avoid issues with the UI initialization order. Particularly, if autoload is off and the Attribute Editor is opened before loading the plug-in manually, the Maxwell-specific attributes will not appear on geometry nodes, lights etc.
Due to a limitation in the Maya SDK, the plug-in cannot be unloaded by unchecking the "Loaded" box. To unload the plug-in, uncheck "Auto load" and restart Maya. If the plug-in is loaded automatically when opening a scene despite cleaning up all the Maxwell objects from it, save the scene with the Maya ASCII format (.ma), open the file in a text editor, look for a line starting with requires "maxwell" near the top, remove it and save the file.
On Windows and Linux, the plug-in depends on the MAXWELL3_ROOT environment variable being set correctly. If this variable is missing or wrong, the plug-in will be unable to start the renderer or the standalone material editor. The Maxwell installer sets this variable on Windows, but you have to update it if you ever move Maxwell to a different directory. See here for more details.
On OS X, the plug-in locates the Maxwell executable by looking at the association for MXS files. This association is set up by Maxwell and Studio when they start up, so make sure you run one of them manually once before attempting to render from Maya for the first time.
I usually select the option because, hey, it's free and it doesn't seem to affect anything in a negative way. If the feature didn't exist I wouldn't miss it, because I have to trust my ears that my mixes sound like I want them to. If I heard aliasing distortion in my mix, I'd do something to get rid of it at that point (like enabling oversampling in the plug-in itself), not rely on oversampling in the rendering engine to clean it up.
I always have a hard time remembering that a 64bit engine is not the same as a 64 bit CPU. The difference being, 64 bit audio processing and rendering is far cleaner than 32 bit simply because of math. But I am not a smart person with all this math hocus pocus so simply is not something one should describe this situation,,,,,,,,,
I may or may not understand the subject in question but it goes a little something like this....ahem!; When recording/rendering/processing in 32 bits there is a problem with the length of the repeating integers that occur in the division of 32 bits. So the long repeating string of numbers that translate back into audio has to be blunted or truncated which introduces artifacts and sample distortion. 64 bit does not have this issue as it divides down into whole numbers so there should or could be faster processing times due to less rounding and blunting a string of repeating integers. The trade off would come in the form of larger audio files which would offset any of the performance gains picked up from 64 bit.
But I predict in the near future things will just be and do and math will never need to happen again!
That's the point. A 64-bit CPU communicates based on the length of 64 bits (or multiples thereof). Be it busses or address registers. Everything can be done on 64-bit wide communication. But that's the hardware side of things.
On the software side of things, apps at all times use data types, that are totally detached from a processor's architecture. We wouldn't have seen the game Elite, which used 32-bit data types although running on a 16-bit processor architecture.
Cakewalk internally uses certain data types to represent audio samples. A sample in dsp is the smallest slice of data in audio streams, a sample point. Because recording audio is done by getting a sample of the original every x seconds, where x is usually very small, like 44100 times per second. The value of a sample is a representation of how strong it makes the membrane of your speaker/headphone/etc deflect outwards or inwards, which is why it is considered to be in the range of -1 and +1, and so naturally such a number will have quite a few digits at times. In the past, for example when working with 16-bit data types, this was less of an issue, because the number was actually stored as a so called 16-bit signed integer, in the range -32768 to +32767. But that means, you only have 65536 descrete steps to represent a sound wave's "curviness". And so DAWs soon switched to using what's called a single-precision floating point format, or single float in short. This is a format that instructs the CPU about the actual value, instead of really being a value by itself. It is 32-bits wide, and this range is divided into 3 fields, the sign, exponent and mantissa. The CPU uses a single to do this calculation: -1^sign * 2^(exponent-127) * 1.mantissa
the sign is 1 bit, the exponent 8 bits, and the mantissa 23 bits. To pass this scary part, let's just say, both exponent and mantissa are limiting. This format can't represent every possible value. And so the cpu rounds numbers to nearest neighbor, if the exact value can't be reached. This makes things imprecise on edge cases. For example, a sound wave's value could become a very small number instead of 0. And many more unwanted effects.
When using "64-bit engine", Cakewalk switches the whole audio stream pipelines to so called double-precision floating point format, or double float in short. A double is 64-bits wide and its exponent is 11 bits wide and its mantissa 53 bits wide. This is still error-prone, but now there is way more headroom, before inaccuracies appear.
This higher precision of course means, that everything takes a tiny bit longer to calculate and the memory usage of course is higher. Both is of no concern if your PC is a rather recent one, say, 5 years old. You also get a higher dynamic range (but of course only inside Cakewalk). As soon as you render to anything other than 64-bit, you will raise the noise floor again.
So just use 64-bit engine mode, whenever you want (best, by activating it via Edit > Settings > Audio > Driver settings, I'm on the German version, so the path might be named a bit differently in English), the downside is neglectable and the higher precision will yield more accurate results (even if often we won't notice them).
In practical terms of audible fidelity, it doesn't really matter whether you use it or not. Leave it on if doubling your memory usage isn't an issue and you just feel better knowing that any cumulative math imprecision is going to be buried so far below the noise floor that it can never matter. But I can think of no real-world use-case where it would be a necessity.
Sure, you can go off into the weeds with the math and convince yourself there's a benefit, and an abstract case can be made that there truly is. But I'd challenge anyone to actually discern a difference in a blind A/B test. It's certainly easy enough to test for yourself: just export the exact same mix with it on and again with it off, then ask someone to randomly select one and then the other while you listen.
