Object instancing/particle animation system for Unity

C# 68.33% GLSL 31.67%

kvantspray's Introduction

Kvant/Spray v2

Spray is a GPU accelerated object instancing/particle animation system for Unity.

Spray is part of the Kvant effect suite. Please see the GitHub repositories for further information about the suite.

System Requirements

Unity 5.1 or later versions.

Kvant effects require floating-point HDR textures to store animation state. Most of mobile devices don't fulfill this requirement at the moment.

No Backward Compatibility

This version (v2) is not compatible with the previous versions. You can't simply upgrade the previous implementation or use two different versions in the same project. Sorry for the inconvenience!

kvantspray's Issues

Error in all three shaders: "cannot map expression to vs_4_0 instruction set"

The error points to this line in the Vertex Shader:
float4 r = tex2D(_RotationTex, uv);

Spray & Reaktor

I would like to use Spray with Reaktor, is there a way out of the box (without good skills for hacking yourself)?
Thanks!

Setting position and color for each particle

Hi,

Thanks for the great repo!

I have a question about whether it is possible by script to set each spray particle's position and color ?

how can i make the particle stretch base on velocity direction?

Particles disappear if gameobject is out of cameraview frustrum

headline basicly says everything :). Is there a way to stop Unity from culling the object?

particle created event

I want to send an osc message every time a particle is created but it i cant figure out where to put my code. I presume because the particles are generated within the buffer and shader?

Could you possibly explain where each particle gets created within your code? Sorry as you can probalby tell I only have a basic understanding of your code.

Thanks

Keith
