FlowMap Painter

[update: check out version 0.9.1]

I’ve been neglecting this blog a bit, but I figured this FlowMapPainter might be a good excuse to post something up again.

It’s been pointed out that the overlay feature doesn’t work. Bit of a bug there that’ll be fixed in an imminent update.

This is actually a bit of a port job. I’ve been working on a vertex painter for Unity as an editor extension, but at some point after adding flowmap painting, I realised it could be quite useful as a standalone (eg. for folks using Cry, Source, Unreal, etc). So I spent a weekend rewriting the relevant bits, and putting together a very rudimentary interface (since most of that wouldn’t port directly over from the Unity Editor API).

From the readme:

This here is a flowmap painter. It serves to make artist-authored (or -tweaked) flowmaps a viable option, where current methods tend to favor simulations via Houdini, for example.
(https://developer.valvesoftware.com/wiki/Water_(shader)#Authoring_a_flow_map)

The tool allows the artist to paint areas of flow, and uses a basic flow shader to immediately preview the results.
It also provides a couple of additional visualisations, such as the actual colors that are being painted, as well as a visualisation of the resulting flow lines.

It’s currently a little rough around the edges; for example, needing to type in the path to your output or custom texture, as opposed to having a proper file browser.

Any and all feedback is welcome, as I continue to work on this.
