¶ Required Tools
An code editor of your choice:
If you choose Visual Studio Code, you need the Python extension aswell!
Other editors work aswell, aslong as they can edit .py (Python) files.
You also might need Maya:
¶ Written Guide
¶ Add matrix to your bin
The first step is adding one default matrix that doesn’t change anything, it is just a blank matrix.
You will add that at the end of your VfxSystemDefinitionData as the video shows here
Transform: mtx44 = {
1, 0, 0, 0
0, 1, 0, 0
0, 0, 1, 0
0, 0, 0, 1
}
¶ How to use matrix
Transformation matrices are usually used in rendering applications due to their mathematical properties. In games, their dimensions are usually 4×4 (16 floating point numbers) and they’re in row-major order (unlike the typical matrices used in classical math which tend to be column-major). They are called “transformation” matrices because they’re a composition of translation, rotation and scale hence they can be used to transform points in a rendering scene.
So you can use these transformation matrices while doing custom particles for any league character.

¶ Editing the size
¶ Decrease
You just need to use a value that is smaller than 1, example of making a particle 2x smaller:
Transform: mtx44 = {
0.5, 0, 0, 0
0, 0.5, 0, 0
0, 0, 0.5, 0
0, 0, 0, 1
}
¶ Increase
Same thing as before, but now you use a value that is bigger than 1, here is a example of making one particle 4x or 2x bigger:
Transform: mtx44 = {
2, 0, 0, 0
0, 2, 0, 0
0, 0, 2, 0
0, 0, 0, 1
}
Result
¶ Moving/ Editing xyz values
¶ Editing the height (Y-value)
By doing so, you move the Visual effect upwards.
Transform: mtx44 = {
1, 0, 0, 0
0, 1, 0, 0
0, 0, 1, 0
0, 250, 0, 1
}
¶ Editing the position (Z-value)
Doing that, moves the particle more to the left or the right.
Transform: mtx44 = {
1, 0, 0, 0
0, 1, 0, 0
0, 0, 1, 0
0, 0, 250, 1
}
Result
May vary, you need to test it a bit in order to get it right
¶ Rotation
For rotating matrix or any complex matrix you can use Maya to do it.
Using this code made by Crauzer to get a transformation as a matrix format.
global proc getTransform()
{
string $objects[] = `ls -sl -l`;
for($obj in $objects)
{
float $matrix[] = `xform -q -m`;
print("Transform for '" + $obj + "':\n");
print("Transform: mtx44 = {\n");
for ($i=0; $i<16; $i++)
{
$value = $matrix[$i];
//$padded = python("'" + $value + "'" + ".ljust(12)");
print($value);
if ($i % 4 == 3)
{
print("\n");
}
else
{
print(", ");
}
}
print("}\n");
}
};
And then you type getTransform with the mesh selected.
