I am writing an expression to get small region (dot shaped) on the planar brighter as a ball bounces on it. I store an array for information(distance) so I need know the exact amount of balls in the scene to limit my array. All balls in my scene have the same suffix (Sphere01, Sphere02.....).

Could anyone help me? :shrug:

not sure if i got you right.
but you could group all your spheres and then read the bounding box information of the top group..

is that what you need?

cheers

Alexx: Yes, that's what i mean. How can you write to read the bounding box information of the top node?

float $minX = `getAttr yourGroupName.boundingBoxMinX`;
float $minY = `getAttr yourGroupName.boundingBoxMinY`;
float $minZ = `getAttr yourGroupName.boundingBoxMinZ`;

float $maxX = `getAttr yourGroupName.boundingBoxMaxX`;
float $maxY = `getAttr yourGroupName.boundingBoxMaxY`;
float $maxZ = `getAttr yourGroupName.boundingBoxMaxZ`;

cheers
