The expected output to the quiz does not seem like something someone would intentionally choose

You didn't present some context on how you reached this content on the website. It looks as if it was an exercise to produce a shader detecting edges based on derivative functions or just sampling neighboring texture pixels.

The title is "Vector of Change" and the description is "Your challenge is to make something as close as the expected shader." and that's all the context you get. It doesn't seem like a very well-designed exercise.

Hey, thanks for sharing this feedback. I am one of the creators of shader academy and I created this challenge. This is ranked challenge, so we do not provide answer and the score of it is used in our ranking https://shaderacademy.com/ranking For now we do not have other ranked challenges, but we will add more in future.

How would you improve description of this challenge? As you can notice, we provide a lot of hints, description etc. for other challenges, but this one is vague on purpose.

Thank you

Personally I know it's about edge detection at the first glance. But I think you should have two things:

1) Make it clear that the lack of instructions is intentional

2) Have a "pixel inspection" tool so we can check the exact RGB values in the expected and diff images more easily.

		Thanks a lot, I think this is valid feedback and we will do that. About 1) we made assumption that for ranked challenges it would be obvious why it is vague, but we can fix it. Thank you!
