Is there an equivalent to the UE4 deferred decal workflow in Unity?

Hello,

I'm new to unity and I'm trying to figure out a workflow I used in UE4 for unity, and see if it's compatible in HDRP or URP?

Specifically, the technique outlined in this polycount thread:

https://polycount.com/discussion/175191/technique-showcase-unreal-4-13-mesh-normal-map-decals

Where the decal sheet is a normal map only shader, and the deferred decal geometry inherits the shader from the object it's being projected onto. I've dug around and the closest i've gotten was a standard lit shader set to transparent and multiply, but it doesn't quite have the exact same effect of inheriting the shader of the object below.

Thanks!

 

Sounds like using just normal maps in the decal systems built into URP and HDRP. Both support just having normal maps and nothing else...

 

I tried using the shader graph/decal, but it doesn't seem to have an alpha channel slot. just the blend alpha as a slider, but no map control.

 

Update. the standard decal does work in HDRP. since there's an alpha map channel. But the Decal in URP does not work.

 

Yep. This is the new trend in Unity. You do everything yourself. Seems backwards, but it is how they are moving forward with many things. Shame.

 

jajajaja i know is a little frustrating, you have to learn now how to make your own shaders (for some specific purpose) and you have to learn all those nodes and all that, but no one is saying that making games is easy, also shadergraph is a great advantage for devs

 

No. Shadergraph is no different to having more bloated options on the component / material instead of you choosing to add them. Except shadergraph is much cleaner and a sensible idea.

I don't know any game engines of any worth anywhere that don't have shader graphs. It's a normal part of game dev.

It would actually become impossible to fit everyone's needs for graphics on a single material, wouldn't it? Have a think about it for a bit.

 

If you use Dbuffer mode in URP. You can do mesh decal (HDRP already uses DBuffer technique). You don't necessarily need to use the decal component.

 

I'm more referring to the lack of support for all the URP Uber-Shaders in Shader Graph itself. There is no support for "Simple Lit", or "Baked Lit", for starters. Adding them yourself is a complete nightmare. URP is used a ton for Mobile, and Simple Lit is the most common path for lighting on Mobile. It boggles my mind that this isn't available.
And no, it's not so simple to do your own lighting, especially when you have objects directly using the Simple Lit shader themselves, and need a Shader Graph shader that gives consistent results.

Yes, Shader Graph is nice... if you use unlit or just lit shaders. Otherwise, the lighting ends up inconsistent. Seems like a pretty basic thing that, again, is a step backwards.

Side-note: URP is still not par with the built-in pipeline. Some missing features, we are told, we have to implement ourselves. This is not the right direction. The functionality AND ease of use should be at least on par, IMO.

 

Mmm i don´t believe the main reason of URP is being at par with built-in (sorry for my english there) but i also think that "Universal Render" is a bad name for that pipeline, LWRP was more acurate. Remember, the "main" reason for URP is to make games mostly for mobiles or mid-(high?) graphics but nothing too great.
