MotionBuilder’s Actor, proc and cons.

Posted on 25 July 2010 Neill No comments

MotionBuilder’s actor, is a handy tool, but it does not have a sufficient accuracy and precision for professional use. Let me explain its proc and cons.

To retarget the animation I started with these issues and achieved some success. At the moment this technology is as internal software of the Sevastopol mocap studio and is used in transfering process for a character animation.

Tip: NPRuntime window handle

Posted on 23 July 2010 Neill No comments

I has found an interesting feature of a NPRuntime plug-in, when I initialize OpenGL rendering context to a particular window handle, and then I need to hide for a while and show a window in browser, using calls style.display = ‘none’ / ‘block’. As I turned out these calls are changing a window handle. This situation needs to specifically monitor, cause OpenGL context is loses.

Tip: Increase last recently opened files count

Posted on 12 July 2010 Neill No comments

Hint about increasing number of recently opened files in the main menu.

In early versions of MotionBuilder configuration files are located in the directory with the program, bin / config.

Starting from 2009 the configuration path has changed and now the path is in the local user data. Almost It’s for owners of Windows Vista and Windows 7.

For example, for my user name “Neill” path is as follows:

c: \ Users \ Neill \ AppData \ Local \ Autodesk \ MB2009 \ config \

Now open a text document <username>. Application.txt

where in the group “UserInterface” there is a property “MaxLastFiles” with the default 4. This value can be changed by yourself to see the required number of recently opened files in the menu.

A good example of sending mail is here - https://forum.antichat.ru/printthread.php?t=44490

If you need a port to C + +, write to me.
P.S. Practice has shown that the service mail.ru better not to deal with. Half day caught cause loss of messages such as “mailbox does not exist”, while the same yandex sent no questions asked.

Mental Ray warn 542003

Posted on 12 June 2010 Neill No comments

I’ve opened a complex scene in Maya for render and for being able to see the cameras better, I’ve scaled them by 10. There are three cameras in the scene. And when it came to render from a camera with a close foreshortening to objects, mental ray could not complete visualization because of the many warnings like

warn 542003: suspect illegal geometry truncating, modify clipping plane

I’ve reverted a scale to 1.0 and solved a render problem.

GLSL shaders tips: NVidia and AMD difference.

Posted on 29 May 2010 Neill No comments

On my personal experience in adaptation glsl shaders to AMD.

I wrote “adaptation”, because this process can not be called in another manner, after setting up under the NVidia card.

1) AMD does not like ARB_draw_buffers require flag in the shader. And if you do not specify any flag at all, shader compiles without any problems. But NVidia gives me a warning that I should include this flag to work with MRT.

When the Cg shaders, there is another story, you need a ATI_draw_buffers flag.

2) AMD swears the presence sampler2DRect and sampler2D in one shader. Also from the category of “not paying attention” on such a warning.

Plugins for MotionBuilder

Posted on 15 May 2010 Neill No comments

I’ve done a small sorting of published plugins, the result is a table of plugins. You can see it, please visit – Plugins for MotionBuilder page

I’ll try to recompile the plugins to new versions of the MotionBuilder, some have already become obsolete.

If you have comments and suggestions, feel free to write!
