Matlab function to create stacked texture maps for Unity

I’ve been experimenting with different materials and shaders in Unity recently. One problem is that especially if you want use the same texture for the same large object you get these nasty tiling effects: Luckily, I found this obscure shader on Unity’s GitHub page, which is amazing but it asked for something called a map texture, which took me ages to figure out.

Finding a U-shape with Bayesian interrupted regression

The outset of the problem In one of my project, I’d like to show that there is a U-shape relationship between two variables. The traditional way to do this would be to fit a quadratic model and test whether the quadratic term is different from zero. However, Simonsohn (2018) among other correctly points out that evidence for a quadratic fit is not enough and there might be situations where the quadratic term is not zero but there is no true u-shape.
