Purpose of this PR
build on top of #952 - Reviewer please use the original PR for review, this one include udpated of Material which make it impossible to review.
Purpose of this PR
Unify surface option between SG and non-SG material UI. Thus this PR adds these properties on the material from SG settings:
Opaque UI:
Transparent UI:
In this PR we also ensure that code for double sided and transparent are always generated, so code must match whatever is selected in the shader graph option.
This PR also expose the following mechanism. There is option that can be exposed from Shader graph to Material by "enabling them" those option are the one that require a blockfield.
Then there is option that simply enable pass, if those option aren't enabled on the SG master node, they aren't visible on the material.
under the hood, enabling option allow to force code generation. Regarding transparent depth prepass, this pass is always generated as it is required for SSR transparent. But for Unlit it isn't.
The behavior for alpha clip is now like this:
If SSR transparent is enabled but not transparent depth prepass, then alpha clip with use the regular alpha threshold, otherwise alpha clip will used the transparent depth prepass threshold. The behavior for regular Material haven't change currently, so enabling SSR transparent will use the transparent depth prepass threshold.
Note: With this PR, all pass work with both anykind of lit based material and also with unlit.
Testing status
I tested
Receive SSR,Receive SSR Transparent,Receive Decals,Blend Preserve Specular,Depth Offset,Transparent Write MVon a Lit SG.In addition to Antoine test above I have perform several comparison
