need help with _SpecularHighlights and _GlossyReflections - can't access them via script

hello world

I need to control these 2 properties from the Standard Shader, while the project is running:

_SpecularHighlights -> which appears in the Inspector as checkbox named 'Specular Highlights'

and

_GlossyReflections -> which also appears in the Inspector as a checkbox named just 'Reflections'

So I need a GUI checkbox that the user can toggle on/off while the project is running.

I already managed to do a similar script that controls other properties of the shader, as _GlossMapScale, but the same approach is not working for _SpecularHighlights or _GlossyReflections

so, this works:

Code (csharp):

1. shapes.GetComponent<Renderer> ().material.SetFloat ("_GlossMapScale", sldfind.value);

but this does not:

Code (csharp):

1.  shapes.GetComponent<Renderer> ().material.SetFloat("_SpecularHighlights", 0);

 

Those shader properties aren't what actually control those settings, they're kind of like placeholder properties to keep track of if that feature should be enabled or not. What actually lets you turn on or off that feature is a keyword set on the material. You'll either need to look at the StandardShaderCustomEditor.cs (I think that's what it's called) StandardShaderGUI.cs, or look at the shader to try and find a keyword that looks right, or try toggling the properties on the material and then use the debug inspector (right click on the inspector tab) and look at the keywords that are being set on the shader.

The keywords are _SPECULARHIGHLIGHTS_OFF and _GLOSSYREFLECTIONS_OFF, and you set them with myMaterial.EnableKeyword("_SPECULARHIGHLIGHTS_OFF")

 

mmm already tried EnableKeyword with no success

gonna try your suggestion as soon as I get home

thank you

it didn't work

this will get the checkboxes to respond but the object is not updated

Code (csharp):

1. gameObject.GetComponent<Renderer>().material.SetFloat("_SpecularHighlights", 1 or 0);

 

Finally! I manage to get this working using keywords and setfloat

like this:

to turn ON:

Code (csharp):

1.  shapes.GetComponent<Renderer>().material.DisableKeyword("_SPECULARHIGHLIGHTS_OFF");
2. shapes.GetComponent<Renderer>().material.SetFloat("_SpecularHighlights",1f);

to turn OFF:

Code (csharp):

1.  shapes.GetComponent<Renderer>().material.EnableKeyword("_SPECULARHIGHLIGHTS_OFF");
2. shapes.GetComponent<Renderer>().material.SetFloat("_SpecularHighlights",0f);

- it's tricky cause there's no "_specularhighlights_on", instead you disable or enable "_specularhightlights_off"

u basically saved my project , thanks a lot ,
I searched the whole web but could not find why its not working

adding both lines of code fixed it for me ,

 

Does it work in build for every materials though? It works fine in editor for me but in build some materials work whiles others not despite using the same Standard Unity Shader in Built-in, Unity 2022.1.12f1.

 

you should create a material with the same details that you want to create from script and include it some where in your project with a reference , otherwise unity might strip that shader from your build and will not include it , so thats why it works on editor , you have to have a sample material with all the different details they might have
I just created a list of materials and assigned different created materials to ti ,
