Rotate texture particle system locally when using horizontal billboard

i have a particle system created using a texture and kept it as horizontal billboard in the render settings but when i try to assign this to an empty parent object and rotate the parent it is not rotating towards the parent. but if i set it to billboard i am not getting the desired output. please help me how to emit particle towards the parent rotation when using horzontal billboard or make it billboard and get the desired way of output.
1. first image: desired output but doesnt rotate when the parent object rotates
2. second image: rotates but the emmission of the particles is not like in the first image

 

in order to have rotation inheritance you can do two things

older unity -> renderer "Mesh" > quad

OR

Unity 2017.x+ you can assign in render view to "Local"

 

renderer "Mesh"> quad doesnt give me the same result. and i am in latest unity but cant find render view any where. please help

 

Renderer > Render_Alignment > Local

 

seems like there is no option as such in 2017.2 and i am installing 2017.3 and hope there is option available and it works as i wished. thanks for your reply though

 

i have unity 2017.3.1, but still there is no renderer allignment option neither billboard allignment option. So what i should do.

 

"Horizontal Billboard" won't give you the options. Switch to render > "Billboard"

 

After switching to "Billboard", still it is not rotating.

 

By selecting the local in Render Alignment, it works. thank you so much for your help

 

I had this issue aswell. when we are using particle renderer with billboard, the rendered particle direction is always the same despite in which direction the particles were emitted. After searching a bit, i found that, we can use a script to set the rotation everyframe.

"In very short : your need a monobehaviour script on your player, in this script get a reference to your particle system, in the Update update the start rotation of the main module of your particlesystem with the player rotation."

This worked for me! hope it helps others.

 

unity out of the box handles this but you must have non-zero speed.
renderer > render alignment -> velocity

• horizontal billboard has no render alignment override
• billboard has render alignment (velocity),

• start speed set it to .0001 (this establishes the vector)

• use 3D start rotation (90x or -90x lacal cone shape this turns a billboard into the plane of existence you want (e.g. horizontal)

• for world_based you compensate for the world Up and any local shape/emitter rotations

• note : world_based often needs cull:none to see both sides of the particles

world based vs local
