Changing lightweight shader "surface type "in c# ?

Hi there,

I'm struggling with the following, could someone please help me with it ?

I'm using the LightWeight Pipeline and my material is using the "LightWeightPipeline/Standard (Simple Lighting)" shader. I'm trying to make my object transparent in certain conditions during runtime (and then back to non-transparent), but I don't know how to change the "surface type" from opaque to transparent at runtime. How would I do that ?

I know I could keep the surface type transparent at all times, but that doesn't look good as it changes the look of my objects.

Thanks !

Jonathan

 

To do something similar, I just switch between two materials, one opaque and one transparent. This has been working fine for me, but if there's a better way to do it, I'd be interested as well.

 

I'm trying to do this as well. Having a separate transparent material isn't really an option for us - there are just too many. Anyone have any other solutions?
Thanks

 

I am switching to the Unlit / Transparent shader when I need transparency at the moment. It's not ideal but works ok for my requirements.

 

I managed to do this with the following:

Code (CSharp):

1.  
2.        private const int MATERIAL_OPAQUE = 0;
3.        private const int MATERIAL_TRANSPARENT = 1;
4.  
5. private void SetMaterialTransparent(Material material, bool enabled)
6.         {
7.             material.SetFloat("_Surface", enabled ? MATERIAL_TRANSPARENT : MATERIAL_OPAQUE);
8.             material.SetShaderPassEnabled("SHADOWCASTER", !enabled);
9.             material.renderQueue = enabled ? 3000 : 2000;
10.             material.SetFloat("_DstBlend", enabled ? 10 : 0);
11.             material.SetFloat("_SrcBlend", enabled ? 5 : 1);
12.             material.SetFloat("_ZWrite", enabled ? 0 : 1);
13.         }
