Rem mklink /D C:\solidangle\mtoadeploy\2016 C:\solidangle\mtoadeploy\2016-1.2.2.0 I start Maya with a batch file that creates a symbolic link named “C:\solidangle\mtoadeploy\2016” that links to the version of MtoA I want to use: rmdir C:\solidangle\mtoadeploy\2016

#MENTAL RAY FOR MAYA 2016 CONTROL SPECULAR INSTALL#

Then I run the MtoA installer and install in a folder with the version name, like this: I take care of that by zapping the Uninstall registry entry with this command: reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall\MtoA2016" /f

As you probably already know, the MtoA installer always wants to uninstall first. If, like me, you need to switch between different versions of MtoA, here’s a recipe for setting that up.įirst, you have to install multiple versions. The older Python bindings still refer to the removed API, so there will be Python errors that prevent MtoA from loading. That’s because Arnold 4.2.14.0 included a number of API changes, including the removal of some API (like AiLicenseSetServer).

You must update the Arnold Python bindings, otherwise MtoA won’t load. For example: C:\solidangle\ arnold\ Arnold-4.2.14.0-windows\ python\ arnold With the python\ arnold folder from the Arnold 4.2.14.0 download. Replace the Arnold Python bindings in the MtoA scripts/arnold folder with the Python bindings from the Arnold python/arnold folder. For example, replace this folder:Ĭ:\solidangle\mtoadeploy\2016-1.2.7.3\scripts\ arnold.Replace Arnold (libai.so, ai.dll, libai.dylib), kick, and maketx in the MtoA bin folder with the versions from the Arnold 4.2.14.0 download.Download Arnold 4.2.14.0 and extract the archive.Shaders can get very complex once you start aiming for photo realism, over time you'll learn all the nuances.until they introduce a new shader again.If you want to take advantage of the improvements in Arnold 4.2.14.0 (like the increase in the maximum number of threads from 128 to 256), here’s what you need to do: unlike the specular layer that would give you just a less reflective area but the reflection itself still remains sharp. I chose the Glossy Reflection because in that simple sphere I needed to convey worn rusted areas so it needed to be glossy/blurred. You can use a texture mask to control the areas of reflection or transparency and that's when Alpha comes into place.Ĭontrolling the highlights in a material with a map means making it shinier or more dull with black, greys and white tones in the texture map to achieve the desired look. No, Specular maps, reflection maps, glossy maps, bump.none of these deal with transparency so alpha is luminance would have no effect. You'll find it in some other important nodes such as displacement and Layer textures, just from the top of my head.

Usually the Alpha is luminance is when a texture has no alpha channel so by checking that ,Mental Ray will use instead the black and white values to generateĪ transparency mask.that is in a nutshell, I get lost with this one sometimes.įile nodes have alpha luminance off by default.
