VFX Graph Vector Array Input
I'd like to create a particle system with the Visual Effects Graph which is basically an OcTree viewer. So the particles will remain completely stationary and the input will be an array of vectors. Is this possible and how would I go about implementing this?
Thank you for your time.

Dos:
Create a
TextureFormat.RGBAHalf
orTextureFormat.RGBAFloat
texture of appropriate sizeFill this texture with your vector array values
Call
texture.Apply()
to send the dataCall
m_visualEffect.SetTexture( "my vectors" , texture );
to bind itSample this texture inside your graph and be merry.
Destroy
texture
when scene unloads so it won't leak.
Don'ts:
do not use
Color32
as it will trim and compress your valuesdo not use
TextureFormat.RGBA32
orTextureFormat.RGB24
as those will clamp your values
