StungaLab – 21³ Cubic Animation Tech Note

Me and a few of my friends (StungaLab) decided to create this animation from last year and I’m responsible for all Unity things – setup / shaders / tools / plug-ins etc. I didn’t help a lot as I have my full-time job in UK so most of the work are actually done by the 2 amazing 3D artists Felix Yin-Zhen Chu and Shadow Chi-Ho Wong, also 2D part by Carol Tsz-Ching Ng. It is the first time for us all to put ourselves into such a big production — target at high quality, massive amounts of assets, and short time-frame, (esp. ) lack of knowledge of using Unity (they are almost the first time Unity user). The final animation really surprised me.

I only have mobile game development experience in the past so there was no way for me to grab so many plug-ins and use so many expensive graphics features in any projects. So I had no idea how to correctly set things up for a project like this. Glad that I work in Unity and the knowledge I gained supported me a good start.

Note: Not everything shown in this blog are being used. But they are the stuff I worked on so I hope to keep them here as a log.

ComputeShader.SetFloats()

Originally I have in

C#

_floatArray = new float[2];
_floatArray[0] = 1f;
_floatArray[1] = 0.5f;

Compute Shader

float FloatArray[2];

And use ComputeShader.SetFloats() to pass the values from C# to Compute Shader.
Reading the values in Compute Shader, I found that only FloatArray[0] has the value. So FloatArray[1] will equals to 0.

Unity dev (Marton E.) replied me that:
