Mental Ray warn 542003

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.

Maya hair. Cache import

Surprisingly noticed that among the functions to work with Hair Cache in Maya there is’t any command to use available disk cache. For example, I calculated the dynamics in a separate scene and then I wanted to throw it in the root scene. On the revenue came MEL script…

Containers in Maya 2009

 I would like to pay a little attention to the new feature of the Maya2009. This is indeed very useful and powerful tool for the rigging/animation pipeline – the containers. I felt the need for something similar when working with a large number of computational nodes. And in order for the entire set of re-use had to copy all the nodes and repeat their connections. This is terribly inconvenient, and with each step makes the scene in the dense forest. But in Maya 2009 was a very rational solution to such problems – to minimize some set of nodes, with all their internal connections to the container. This container can be reused through simple copy or import, and all incoming / outgoing connections, you can declare a very specific names, which will be convenient to work. An opportunity to create the computational power for TD. What is the most dainty of this piece, the development can now be put in parallel parts. This is stored in the proper organization is indeed a very good potential.

Maya script pack for animation 1

Набор скриптов для простого анализа и обработки анимации

All scripts are ideas, not the ultimate tool

Accel Path – acceleration of a curve for a given object. This curve allows you to compare joints in motion
Center of Mass – builds a center of mass for FBIK character. A useful tool in the analysis of equilibrium positions
offsetToCenter - animation brings this point in the center (used with MoCap)
portingAnim - copying keys from one skeleton to another
scaleKeys – scaling keyframes

Geometry warning, bone is N degrees away from it’s roll axis

When you preparing your skeleton to export to MotionBuilder, You need to be sure that all your roll bones lies on their parent’s roll axis. What does it mean? To answer, look at the parent local axis direction. It must look at the roll bone’s child. It’s like you can create a line between parent and child bones of the roll bone and check if you roll bone lies on it. Roll bone just devide this line without any bends.

On the left – wrong roll bone position, on the right – good roll bone position

Another very important thing is to make it clear that your bones orientations are alined. Maya has very usefull command to do that – orient joints tool.

Mesh vertex info

Написал простой но весьма полезный плагин. Он достает из заданного мэша позицию и нормаль для указанной вершины.
Тонкость работы заключается в том, что позиция вершины не учитывает трансформацию объекта.

Установка
Плагин для 2009й Майки
Если кому интересно, могу поделиться исходниками или перекомпилировать под другую версию майки.

Скопируйте файл плагина в директорию bin\plug-ins

Подготовка к работе

1 создайте вспомогательную ноду данного плагина
createNode vertexContstraint;

2 добавьте для созданной ноды входящее соединение от некоторой геометрии в канал inMesh

3 теперь назначьте исходящие каналы position и normal, которые будут передавать информацию по вершине с номером vertex index
