expression via mel

Introduction to Maya - Rendering in Arnold

This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Ahoi,

I have a question concerning expressions via mel script. for some reason it seems to work - no errors... but no expression is being written into the locators. (i have particle called pLetter_Zero. then want to figure out the particle-count, create as many locators and place them to each particle via expression)

any input is much appreciated!

int $partCount = `getAttr ("pLetter_Zero" + ".count") `;

for( $i=0; $i<$partCount; $i++ ) {

spaceLocator -n ("pLocator" + $i);
string $particleLocator[] = `ls -sl`;

string $exprX = ($particleLocator[0] + ".tx");
string $exprY = ($particleLocator[0] + ".ty");
string $exprZ = ($particleLocator[0] + ".tz");

string $cmd = " \
float $particlePos[] = `particle -id $i -at worldPosition -q pLetter_Zero`; \n\
$exprX = $particlePos[0]; \n\
$exprY = $particlePos[1]; \n\
$exprZ = $particlePos[2]; \n\
";

expression -s $cmd;

}

everything starts and ends in the right place at the right time.
