ShaderGraph/LW how to create a simple lit graph?

Hello,

It seems that it's not yet possible to create a non PBR graph with the lightweight render pipeline and shadergraph. Is this feature planned or not?

 

Bump because I asked this same question a while ago and didn't get an answer either. As is stands I'm assuming we should use the unlit graph and implement our own simple lighting - is that right? Or is a simple lit graph on the way?

 

Bump. I'm worried I'm being stupid here - is this a stupid question? @phil_lira @Andy-Touch?

 

Just out of curiousity, what kind of non PBR stuff that you guys talking about? NPR?

 

@Reanimate_L basically in LWRP there's a 'simple lighting' standard shader, which I'm assuming is more performant than the PBR shader, but when using the shader graph you can only choose from PBR or Unlit.

But maybe the performance impact is negligible - I'll be honest I haven't profiled. But I'm making another assumption that the simple lighting shader exists for a reason!

 

The SimpleLit shader is not physcally based, just simple lighting, like the old diffuse. It's good for some mobile applications, and also for mobile VR/AR.

 

hmm i think it possible to create simple diffuse with the current lwrp. i remember some one manage to create custom toon shading in lwrp.

 

That was @Andy-Touch and he implemented his own simple lighting in shadergraph - not using any scene light data etc.

 

no not him.

He still had to use a PBR master node for casting / receiving shadows.

 

well then you can only wait from unity team then

 

or write a custom master node, although I still havent worked out how to do this! Woud love to though as it opens up shader graph for any shader type

 

Yes, it seems like this isn't possible and for this reason it seems like it's also not possible to use, for example, the HDRP subsurface scattering presets with Shader Graph. Is that planned at all for the future?

 

This is already in, and for a long time now. Right now there aren't full docs for anything. SRP Core, LWRP, and Shader Graph are all coming out of Experimental/Preview with the release of Unity 2019.1 so you can expect the documentation for those to come with the release, then things should be more clear.

 

Yes, it would be great to have information on how to do that. How do you open the Lit shader in the ShaderGraph? I can only seem to get to the PBR shader.

 

You need to be using a version of HDRP that includes the Lit Master node and a version of Unity that supports it. I recommend updating to the latest beta of Unity 2018 with is currently on Beta 10 or wait until 2018 is fully released in a few weeks as well as using the latest version of HDRP which is currently 4.2.0 (This will give you shader graph 4.2.0 which has the Lit Master node as well as well as some other HDRP Master nodes)

 

Any update on this @phil_lira?

 

I need a variation of this for a diffuse sprite. Currently it is impossible to crate a sprite that can receive simple lighting.

 

@izym Is there any update on this?

 

bump

 

I'm also very interested in this. Would be really great to be able to create Simple Lit graphs. Glad to hear it is planned!

 

any updates?

 

Any ETA?

 

@FeedMyData FYI, I've just released a package on the asset store that gives you just that: a SimpleLit master node.
In addition, it add more than 30 noises that I felt were missing in ShaderGraph, including Perlin 2D/3D, fractal ...etc.
ShaderGraph Essentials on the asset store

Sorry, it's probably not the right channel to do some promotion, but the package does solve your problem

 

Looks nice but I am not sure how worthit it is to purchase an asset built on beta tech, considering you dont support 2019 currently yet the 2018.3 api is drastically different and so is its feature set, I think getting this asset will just lead to headaches down the line. I will revisit it once 2019.1 is out of beta and once you support it, but dont take this as unappreciative as it looks like nice work

 

No offense taken, you have a very valid point ! To be honest when I talked to people, the main thing they were interested in was the noise nodes / bake texture, not the SimpleLit master. Plus Unity will probably release it on its own at some point.
The 2019+ support was definitely a question I asked myself before releasing the asset; and I did so because I'm confident I can port the noises, and pretty confident I can port the "Bake Texture" feature. I also got an extensive list of features I want to add.
Thanks for your feedback @GameDevCouple_I

 

Bump. Want this feature please!

 

@GameDevCouple_I you might be interested to know that ShaderGraph Essentials (Asset store link) now supports 2019.1!
A few people use it with this version already!

 

Thanks! There're still a lot of features I want to add!
ShaderGraph itself is really nice, thanks for developing it! Of course there are a lot of feature request and possible improvements, but it's already helping a lot of people getting in shader and graphics in general ... and that's really cool!

 

Any update on this yet?
