I'll add support for this in the next update

Unfortunately, the instruction count isn't exposed in a nice way in Unity.
I can extract it from the compiled shaders, but if Unity ever change the output of it, I have to rewrite the parser for it.

I've talked to Unity about it as well, but they don't seem to want to expose it in a neat way, saying that the instruction count isn't very accurate in measuring performance (which is partially true) anyway.

In the meantime:

• If / Step can be expensive, especially on mobile
• It's expensive to use a texture to calculate the UV coordinates for a second texture, especially on mobile
• Trigonometry is a bit expensive
• RGB to HSV is a bit expensive

Yeah, I didn't have the time to implement the UI specific properties for it. It had more implications than I thought at first, I need to customize the interface and modify the property system to make it work like this.
Sorry that it didn't come with 1.18, I'll definitely add it for 1.19

This has now been implemented in 1.18

Silly bug! I'll look into this for 1.19 :)

There probably is, but I can look into implementing some features to make this easier in the next update :)

This has now been fixed in 1.18. No more artifacts + this node :)

I did update ArcTan2 now for 1.18 though - you can now select between these:
