Question Set matrix values via properties without a extra Vector4s?

I'm writing a sprite skew shader to replace an old one since I've moved to the Universal Render Pipeline.

It's a simple shader but in the original I just piped the floats directly into the 4x4:

Code (CSharp):

1. float h = _SkewH;
2. float v = _SkewV;
3. float4x4 transformMatrix = float4x4(
4.     1,h,0,0,
5.     v,1,0,0,
6.     0,0,1,0,
7.     0,0,0,1);

Now I can't figure out how to get those same properties into a matrix without creating extra Vectors, which just seems a bit wasteful:


Thanks in advance for any pointers. I know it's a minor thing, but I'd like to avoid the extra vectors if I can.

 

You could use a custom function node and have 2 input and have Matrix 3/4 Output.
Than you can use the code like in your code example.

 

Thanks! That's exactly the sort of thing I was hoping was possible.
