G'day, cheers for the feedback.

I didn't end up getting a mixed effect so the 'trail' is just alternating (as per the screenshot). Was keen to make it prettier but was a bridge too far in the time. If yours isn't like the screenshot it might be an issue, possibly related to support for compute shaders. 

It is definitely something that could have been done trivially with a few spirits and maybe 20 minutes of coding... It was just a personal desire to explore compute shaders. It really could have been done better as a standard shader but was a vehicle for understanding the compute shader pipeline. Just glad you managed some enjoyment out of it!

Cheers.

Only had 4 hours and used it as an opportunity to try and learn compute shaders (game logic all shader based) so didn't get time to develop it much. Happy with the end state though (even if it could have been done in half the time using normal game logic!)

Cheers. A bit of fun in a super short time. Might use the idea and recreate it outside a shader to expand on it a bit of I get a chance!

Cheers - would love to have had more than a few hours to flesh it out a bit more (and potentially move the gameplay logic from compute to regular shader for web version!)
