Sat, 29 Nov 2014 04:59:19 UTCHow many CPU cores are used by the iray renderer?MaxStation<p>If you check the render log when you're using the iray renderer with both CPU and GPU you may notice something strange (in this example the machine has 24 CPU cores and a Quadro 4000 GPU):</p> <p style="padding-left: 30px;" class="code">RC 0.10 22 MB info : progressive: using iray renderer</p> <p style="padding-left: 30px;" class="code">IRAY 0.10 39 MB info : found 1 CUDA devices</p> <p style="padding-left: 30px;" class="code">IRAY 0.10 39 MB info : using CUDA device 0</p> <p style="padding-left: 30px;" class="code"><strong>IRAY 0.10 39 MB info : using CPU rendering with 24 thread(s)</strong></p> <p style="padding-left: 30px;" class="code">...</p> <p style="padding-left: 30px;" class="code">IRAY 0.58 58 MB info : Rendering with 2 device(s):</p> <p style="padding-left: 30px;" class="code"><strong>IRAY 0.58 58 MB info : CPU (23 threads)</strong></p> <p style="padding-left: 30px;" class="code">IRAY 0.58 58 MB info : CUDA device 0 (Quadro 4000)</p> <p style="padding-left: 30px;" class="code">IRAY 0.58 58 MB info : Rendering...</p> <p class="code"></p> <p>So initially it says it's going to use both the CUDA device and 24 cores. But just before the actual rendering begins it shows you that it's using one cpu core fewer.</p> <p>There is a good reason for that: in order to get the best possible performance one CPU core is left unused by the iray renderer. That core will be managing the GPU(s), if that core would also be rendering it would cause a drop in performance as the code that gets and sends information to the GPU would be competing for clock cycles with the actual rendering.</p> <p>If for some reason you want to use a specific number of cores (but less than the total number available) you may want to configure one additional core for iray to use.</p> <p>If you don't use the GPU for rendering the exact number of CPU cores you've configured will be used.</p>Thu, 27 Nov 2014 14:53:40 UTC Making sure scenematerials array is up to dateMaxStation<p>The problem:</p> <p>In a new scene cre<span style="line-height: 1.5em; font-size: 14px;">ate an object, a</span><span style="line-height: 1.5em; font-size: 14px;">ssign a material and then delete the object. If you now&nbsp;</span><span style="line-height: 1.5em; font-size: 14px;">check scenematerials it still shows the material. When you run "scenematerials.count" it still shows 1.</span></p> <p>The solution:&nbsp;</p> <p><span style="line-height: 1.5em; font-size: 14px;">You need to save the scene, that causes the scenematerials array to get cleaned up. On a large file that might take a long time, luckily it is enough to call "savenodes #() somefile". That will be quick as it saves an empty array of objects.</span></p>Mon, 24 Nov 2014 14:00:03 UTC error &quot;Could not find the specified file in DefaultSettingsParser::parse() ;&quot;MaxStation<p>The error "<span style="font-size: 14.4444446563721px; line-height: 1.5em;">Could not find the specified file in DefaultSettingsParser::parse() ;" occurs if you don't have the Populate Data installed on the machines.</span></p> <p><span style="font-size: 14.4444446563721px; line-height: 1.5em;"><br /></span></p> <p>This is what the errors will look like in the log files:</p> <p>In the server log (backburnerserver.log):</p> <p class="code" style="padding-left: 30px;">2014/11/14 09:33:24 INF New task assigned: 0</p> <p class="code" style="padding-left: 30px;">2014/11/14 09:33:26 INF Adapter returned unexpected code -2 for "C:\\Program Files\\Autodesk\\3ds Max 2015\\maxadapter.adp.exe" "-o" "NewTask" "-l" "Info" "-j" "C:\\Users\\bb\\AppData\\Local\\backburner\\ServerJob\\Untitled01.xml.details" "-s" "0" "-n" "1" "-a" "C:\\Users\\bb\\AppData\\Local\\backburner\\ServerJob\\" "-d" "utf-8"&nbsp;</p> <p class="code" style="padding-left: 30px;">2014/11/14 09:33:26 ERR Task error: 3dsmax adapter error : Autodesk 3dsMax 17.2 reported error: Could not find the specified file in DefaultSettingsParser::parse() ; Could not find the specified file in DefaultSettingsParser::parse() ; Could not find the specified file in DefaultSettingsParser::parse() ; Could not find the specified file in DefaultS&nbsp;</p> <p class="code" style="padding-left: 30px;"><span style="line-height: 1em; font-size: 14px;">2014/11/14 09:33:26 ERR 3dsmax adapter error : Autodesk 3dsMax 17.2 reported error: Could not find the specified file in DefaultSettingsParser::parse() ; Could not find the specified file in DefaultSettingsParser::parse() ; Could not find the specified file in De</span></p> <p class="code" style="padding-left: 30px;">2014/11/14 09:33:26 INF Application is down</p> <p>In the manager log (backburner.log):</p> <p style="padding-left: 30px;" class="code">2014/11/14 09:33:26 WRN Task error from fara06253</p> <p style="padding-left: 30px;" class="code">2014/11/14 09:33:26 ERR Job 'Untitled01' (Autodesk 3ds Max 2015 (64-bit)) failed for fara06253</p> <p style="padding-left: 30px;" class="code">2014/11/14 09:33:26 ERR Error message: 3dsmax adapter error : Autodesk 3dsMax 17.2 reported error: Could not find the specified file in DefaultSettingsParser::parse() ; Could not find the specified file in DefaultSettingsParser::parse() ; Could not find the specified file in De</p> <p style="padding-left: 30px;" class="code">2014/11/14 09:33:26 WRN Server fara06253 flagged as failed for job 'Untitled01'</p> <p></p> <p>To resolve the issue you need to ensure that the Populate Data is installed on all the render machines.

And if so, how often do you look at this file?</p> <p>For me the answers are:</p> <ul> <li><span style="font-size: 14px; line-height: 1.5em;">yes, it's in&nbsp;C:\\Users\\[my user name]\\AppData\\Local\\Autodesk\\3dsMax\\2015 - 64bit\\ENU\\Network\\</span></li> <li><span style="font-size: 14px; line-height: 1.5em;"></span><span style="font-size: 14px; line-height: 1.5em;">and no, i don't really look at the file.</span></li> </ul> <p>Uhm, so why do i have Errors, Info, Warnings and Debug all ticked (in preferences-&gt;files under the log file maintenance section)? Now that's a good question!</p> <p></p> <p>Back to the topic: some mesh operations can take longer because of the mesh inspector (introduced in the 2014 release) logging information in that log file.</p> <p>Aha, so i can speed that up by:</p> <ul> <li><span style="font-size: 14px; line-height: 1.5em;">disabling the mesh inspector (that helps)&nbsp;</span></li> <li><span style="font-size: 14px; line-height: 1.5em;">or by unchecking the logging options (that helps even more and i get to keep the benefit of meshes getting automatically fixed if required). In fact you only need to uncheck the Info option.</span></li> </ul>Wed, 22 Oct 2014 12:00:20 UTC performance of final gather in mental ray when rendering at a very high resultionMaxStation<p>The default final gather algorithm is faster and produces nicer feedback but also uses more memory, that's find for resultions up to HD but if you go for very large, something like 20000x20000 mental ray will allocate a lot of memory which will cause the machine to swap to disk a lot if you don't have sufficient physical memory.</p> <p></p> <p>The workaround is to use the following string option to force mental ray to use the old algorithm (render setup-&gt;string options in the renderer tab of the mental ray renderer):</p> <p class="code">"finalgather precomp legacy" true</p> <p></p> <p>That will allow the render to complete faster because the machine won't be swapping tho disk.</p>Tue, 21 Oct 2014 11:17:51 UTC Autodesk Software for Students, Teachers, &amp; Schools Around the WorldMaxStation<p>The terms have changed: now ALL students, teachers, and schools everywhere in the world have FREE access to our desktop software.</p> <p>In the past, we have had free access in some countries, but not others.

And make sure the pivot is at z=0 otherwise we'll get problems when we use the lookat controller later on.</p> <p><img src="/userdata/blogs/maxstation/nicolas/cab-trailer2.png" width="400" height="300" /></p> <p>Parent the trailer to the cab</p> <p>Use a path controller to make the cab follow the path (in the Motion panel select the position and use the assign controller button to select the path controller, then add the path)</p> <p><img src="/userdata/blogs/maxstation/nicolas/cab-trailer3.png" width="400" height="300" /></p> <p>When you now play the animation the cab follows the path with the trailer rigidly attached. Not really what we want!</p> <p>To make the trailer follow the path we use a dummy that's slightly behind on the path and use a lookat controller on the trailer that points at this dummy. You can tweak how the trailer follows the path by adjusting how far the dummy is behind the cab.</p> <p><img src="/userdata/blogs/maxstation/nicolas/cab-trailer4.png" width="400" height="300" /></p> <p>And <a href="/userdata/blogs/maxstation/nicolas/">here is the file</a> if you want to play with it yourself</p>Fri, 25 Jul 2014 14:23:01 UTC lots of custom attributes in one go with MaxScript - part 2MaxStation<p>Yesterday's script would remove all custom attributes, looking at a sample file i got hold of many of the customer attributes didn't have a definition (and could therefore be safely removed), but some did hold definitions (and most likely you'd like to keep those). So here is a script that does just that: instead of repeating the code we define a function that will remove the custom attributes.
