Erosion flow direction

Hi all,

Is there a way to obtain the flow direction of the erosion device? I need to create flow maps for my application with Red being the flow’s strength on the X axis and Green on the Y axis (0-127 is -X or -Y and 128-255 is X or Y).

Thanks.

Hmm, interesting question.

There’s currently no automatic ability to do this. However:

The erosion flows do occur in the direction of the surface normal projected onto the surface, so in theory you should be able to do this by using the Normal Map generator device and create a normal map.

I’ve created a small example file showing this. check it out and see if it can do what you need! Usefulness will probably depend on your application…

Wow that’s exactly what I needed… THANKS!

Great to hear. Would love to see what use you’re putting this to when you get things finalized!

Holy cr* Dudes!!
This is advanced stuff, I like it…
I have no clue what you to are taking about, but it sounds awesome.
I am trying to make flow maps like this http://phill.inksworth.com/vector-maps-for-water-flow-materials-in-udk/

Your tutorial might help me.
Until next time Stay sharp.
