Flow v1.6.5 has been released

Flow shader creates real time flow effects using flow maps. Package contains 20 high quality - SM3 shaders and 21 optimized mobile version shaders.
Shaders are divided into several groups with more or less complexity. Complexity and quality of the shader is controllable.
Shader supports: Diffuse, Specular, Bump, Transparency, Emission, Parallax, Reflection, Refraction (fake Refraction for Unity Free), Noise, Lightmapping etc.
All scenes from promo video are inside package.

• Support Unity 4 DX11 (Fixed bugs in DX11 mode).

Update v1.1
• Improved all shaders (redused instruction count).

This is super cool man. A bit pricey maybe, but it seems worth it I guess. :slight_smile:
Good job.

A+!
This is going to make rivers so much better, since flow now gets obstructed by rocks. Please post some more videos with rivers and rocks in them:smile:

4

Thinking of using this for rivers and waterfalls. Would love to be sold with more videos and or info. :slight_smile:

5

nice. Good to see the shader properties

6

Nice, interested in buying this package but are they compatible with Unity 4?

7

Well worth a $100. any good for mobile?

8

Sent you a PM a few days back.

Hi
I have submitted new version of Flow with mobile support. After review it will be on asset store. Everyone who already purchased Flow, will get update for free.

10

Hey do you have suggestion with what software is best to create river flow map?

11

@janpec

There is documentation inside Flow package, describing flow maps and how to create, draw or generate them.

Hi, the river video is impressive.

The tears too.

I can see it working on a car windscreen to simulate rain.

@pulov
As of course, it’s really easy with Flow. Check this video

14

I’ve just asked about possibility of this going into asset store madness… And, haha, so that is how you deal with potential new costumers?
Good to know, less $100 bucks in your pockets, budy. Enjoy!

@BrUnO XaVIeR
Bad behavior.
If you have any questions ask them here.

16

Can this work on terrains? Or do I have to place a “dummy” terrain as a mesh?

17

Unity terrain has it’s own shader, so Flow can not replace terrain base shader.

18

Do you provide software for creation flow maps, or at least do you know which one to use? Also i am guessing that river has to be UV unwraped in 1:1 space for flow map texture right? If thats so that means that for bigger rivers you would need to stick few rivers together.

19

Well some shaders like only 1 color rim shaders do not need UVs since its only 1 color on object.
Thanks for river flow informations.

@Arkhivrag It would be helpful to list those free packages with URLs. Being able to easily edit flow maps is something developers evaluating your package will want to research, since no editor is included in your asset, only guidelines for Photoshop.

We are watching this asset for a potential buy, but are waiting until it matures and any bugs are found/fixed, and to read feedback from other community members on the quality of the asset and support. Were it on sale, we would buy it sooner.
