Particle Vertex Streams real scale of a particle

Unity Engine
1

Hi, I want to use the vertex offset in particle shader. For example, I want to move particles 1 unit up, so when particle system is at a scale of 1, each particle moved 1 unit up normally, but if I scale the whole particle system to 0.25, particles still moved 1 unit up. The Size vertex stream sending just the size of particles, not its real scale in world space.

So, my question is - how can I pass the world/lossy space scale of a particle(or world/lossy scale of a whole PS) in a material without using C#?

Unfortunately you can’t. The closest you can do is use instanced particles and extract the scale from the transform matrix.
