How can I emit particles in specific directions


Currently, the particles I’m emitting emit in a circular shape, but I want them to emit out in specific directions, specifically in the directions of the highlighted areas.

Is it possible to achieve this?

おそらく現在の放射状態は「from point」になっていると思います。
なのでこれを「InCone」に変更することでおそらくお望みの領域の放射が可能となります。
また放射の方向が右向きと左向きの2つを作る必要があり、それぞれx軸で放射した場合「左向きのConeAxisのxに1を」「右向きのConeAxisのxに-1を」設定することで望んだ形状を実現できます。
また、角度の調整はConeAxisの下のConeAngleから行うとよいでしょう。

It can be done in single emitter

My apologies, I should’ve shown what I wanted with a 3d model, I wanted it to emit more in this shape.

Best way is to calculate custom vector like here. Input A is direction mask for a vector you can make a parameter out of it. 1, 1, 1 is normal point velocity and you limit or increase each axis with this vector

I don’t know if I’m doing something wrong, but when I recreate this setup it just travels in a straight line.


Your Velocity above is set to be Linear, which means all particles will move along a single vector.
You want to set your Velocity Mode at the top to be “Cone”, which will give you the spread you’re looking after.
