Transparency, Render Queue, Depth, Sorting ZWrite Problem - on Build

Unity Engine
1

I have the same problem, and have looked at articles/posts everywhere trying to figure out. I cannot figure out the solution either.
It may be:
1. Render Queue problem?
2. A shader problem?
3. Something needs to be adjusted in the settings?
** I don’t think its a bug, then I’ve been seeing posts about this all the way back to 2015.
** Code seems to work fine, because it works okay inside unity…just not on build.

Attached is the Video and Code of what is happening

// Update rendering mode
                    if (visible)
                    {
                        // Opaque
                        material.SetFloat("_Mode", 0f);
                        material.SetInt("_ZWrite", 1);
                        material.EnableKeyword("_ALPHATEST_ON");
                        material.DisableKeyword("_ALPHABLEND_ON");
                        material.EnableKeyword("_ALPHAPREMULTIPLY_ON");
                    }
                    else
                    {
                        // Transparent
                        material.SetFloat("_Mode", 3f);
                        material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.SrcAlpha);
                        material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);
                        material.SetInt("_ZWrite", 0);
                        material.DisableKeyword("_ALPHATEST_ON");
                        material.EnableKeyword("_ALPHABLEND_ON");
                        material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
                        material.renderQueue = 3000;
                    }

                    // Update color
                    if (material.HasProperty("_Color"))
                    {
                        var color = material.color;
                        color.a = (visible ? 1f : 0.2f);
                        material.color = color;
                    }

You’re enabling features on the material that are for shader variations that are getting stripped from the build. You need to use a ShaderVariantCollection to make sure they’re included. Run in the editor for a while, then create one from the Graphics settings menu by clicking on Save to asset… at the bottom of the inspector window.

That worked! For others wondering how exactly it got fixed see below:

  • I went to Edit > Project Settings > GraphicSettings

  • Hit Reset (on the gear)

  • Scroll down to “Save to Asset” a NewShaderVariants

  • On the NewShaderVariants

  • Click the + under Standard (Specular Setup)

  • Add whatever shader variant you had in your code, In my case it was “AlphaTest”, “AlphaBlend”,AlphaPremultiply" / ForwardBaseDirectional_Alpha***

  • Go back to Edit > Project Settings > GraphicSettings

  • PreloadShaders > Size 1

  • Element 0 load up your NewShaderVariants you just created, and edited.

Thats it!
