unity-renderer Outline Shader Advance

Shader info

MUST :

--> outlining alpha

--> control the online shape.

--> single solid color

--> or gradient outward

--> or it could also act as a mask for ultrarainbow color movement

--> rendered behind objects, and the inner mass of color may be faded with a overlay color mass when clicking, the effect may blink or change color.

MUST NOT -- DONTS

X : red lines: cant use duplication of geometry, and cant replace the geometry shader X : not based on geometry displacement

Working on feedback adjustments

[x] Transparent objects issue (ZDepth related)
[x] Objects with open uvs
[ ] Multiple mesh objects

For transparent objects that have problems solution is

Add this transparent object to a Layer ( TransparentOutlined on my example here)
Add those 2 render features that only apply on this layer

Coin issue is Overlapping UV's , cant be solved in the outline shader as we do calculations on that area of the shader.

I need to come up with another solution OR change the uvs of the coin

Oct 04 '22 14:10 MichaelBitsakis

We can keep the outlines connected by setting the Overlay Amount to 0 in such scenarios

Oct 04 '22 14:10 MichaelBitsakis

Transparency issue solved within the shader and the transparent material (use v2 shader and on the shader material disable the receive shadows)

New Post Effect Core To URP (WIP / during translation)

Oct 05 '22 12:10 MichaelBitsakis

Outline Replica from PostProcess to URP Render Feature

Current Features : Color , Width , Object Occlusion , Pseudo Blur

State : Wip , need to write the controls , clean it and stabilize the code.

Oct 05 '22 15:10 MichaelBitsakis

Progress :

All cases EXCEPT CPU Skinning (Toon Shader) are working fine.

I will need some time to implement the outline to the custom GPU Skinning.!

Shader based (per object without layers control) WIP progress. Based on the previous Render Feature version but in shader .

Oct 17 '22 12:10 MichaelBitsakis

Finalizing this shader only approach with internal on/off feature flag

Oct 20 '22 07:10 MichaelBitsakis

Outline Combined Solution to a shader only setup

WIP on Avatar (on rest of the items works as expected)

Work in progress

Progress 2 on Outline Avatar ,

More stable but i need to separate and use more passes to behave as we need it. Plus i need to separate objects from Avatar as i am forced to use different algorithms , again everything is going to be controlled from one shader only

Working on it.

Implemented Outliner Straight into Toon Shader

Working GPU Skinning included (also in separate version)

Needs some tweaking to get the exact same look.

Oct 24 '22 11:10 MichaelBitsakis

Fixed glitch now as you can see in the video we have rock steady outline .
Unfortunately now we have partial transparency passing through the shader ONLY in camera view , so it probably a combination passes again , will find fix that one as well.

Transparency coming through ALMOST solved!!!
