Question Fur shader using LWRP and Shader Graph

Hi everyone, I've used SG quite a bit in recent weeks and come to appreciate it. As someone who doesn't have a background in hand-coded shaders, I also wonder about it's limitations. Specifially, would it be possible to build a (simple) fur shader using only SG and targeting the LWRP?

Any ideas would be appreciated.

Here's a nice example of what I'd like to achieve (example taken from a game called Fluffy Fall):

 

have been giving this a lot of thought my self. Currently my research points to using a parallax effect, kind of like the ice cracks technique but inverted.

Another idea is to use the grass technique and apply some world position based noise, so when the object moves around, the fur is pushed around

 

Cool, if you manage to prototype any of that, make sure to post it here

 

I had a look at the Fluffy Fall video.

It's implementing fur with the "shell" technique, and there's plenty on the store.

It's basically taking the base mesh, replicating it with some delta position, and "inflating" it in the direction of the vertex/pixel normal. Just iterate on this, possibly applying an erosion shader to the same texture, to give the feeling of extrusion. Or, use a noise function fading from 1 to 0 alpha gradually on every shell.

The "brute" way to do it would if you're really in a hurry is faking it by actually duplicating the same mesh with different scale values and overlapping them.

Of course, it's not as performant, but gets the job done in a minute. Make sure to use an appropriate texture to simulate shadows (baked)

You can as well simulate the wobbly effect by displacing/rotating the array of shells in the direction of the motion. You can do it both in the shader version or in the quick and dirty way

Detail of the shell shader:

 

@WendelinReich this is using shader graph LWRP on a single sphere, inspired by the ice crack tutorial

 

Really interested if this has progressed any further. No pun intended. But seriously, I'd love to know if this might be possible with shader graph.

 

the above was done in shader graph

 

can you share it?

But this does not really give you a furry outline.
You would still need to place haircards on the character mesh to give it some volume and outline.
