 Happy radish - shader test

start this a couple weeks back and struggling to find the time to finish it, but I think it's cute

hey anon, no idea when this was posted tumblr’s terrible for messaging it seems.Designer’s fine for making ‘hand painted’ stuff. Most things you think are hand painted aren’t, even in WoW these days a lot of the assets are sculpted and then the textures are generated by filtering the height map.

And building height maps and then abusing them is what Designer is all about :)

this one’s a bit friendlier 

had a little go with ShaderToy today, made a relaxing spiral https://www.shadertoy.com/view/4ljyD1

Environment shader from my Global Game Jam entry

Got asked to share this so without further ado, and absolutely not cleanup or explanation of how it works, the shader:

// Upgrade NOTE: replaced '_Object2World' with 'unity_ObjectToWorld' Shader "Unlit/EnvPulse" { Properties { _MainColor ("Main Color", Color) = (1,1,1,1) _Pos ("Pulse Position", Vector) = (0,0,0,0) _PulseStart("Pulse Start", float) = 0 _PulseSize("Pulse Size", float) = 2 _EdgeDistance ("Edge Distance", float) = 10 _PulseSpeed("Pulse Speed", float) = 10 _LightingPower("Lighting Power", float) = 1 _PlayerPos ("Player Pos", Vector) = (0,0,0,0) } SubShader { Tags { "RenderType"="Opaque" } LOD 100 Pass { CGPROGRAM #pragma vertex vert #pragma fragment frag #include "UnityCG.cginc" struct appdata { float4 vertex : POSITION; }; struct v2f { float3 lighting : TEXCOORD3; float3 worldPos : TEXCOORD2; float4 vertex : SV_POSITION; }; float4 _MainColor; float3 _Pos; float _PulseStart; float _PulseSize; float _EdgeDistance; float _PulseSpeed; float _LightingPower; float4 _PlayerPos; v2f vert (appdata_base v) { v2f o; o.vertex = mul(UNITY_MATRIX_MVP, v.vertex); // fresnel float3 viewDir = normalize(ObjSpaceViewDir ( v.vertex )); float fres = 1 - saturate ( dot ( v.normal, viewDir ) ); fres = pow(fres , 2)* 0.5; // normalize(WorldSpaceViewDir(v.vertex)) // v.normal // down light // mul ((float3x3)UNITY_MATRIX_IT_MV, v.normal); float3 norm = mul ((float3x3)UNITY_MATRIX_IT_MV, v.normal); float downLight = saturate(dot(norm, float3(0,1,0))); downLight = downLight * 0.2; // combine lighting o.lighting = max(fres, downLight) * _LightingPower; //o.lighting = pow(o.lighting, 2); o.worldPos = mul (unity_ObjectToWorld, v.vertex).xyz; float dist = distance(o.worldPos, _Pos) ; // pulse //float purePulse = dist - (- _PulseStart); float pulse = saturate(dist - (_Time.y - _PulseStart) * _PulseSpeed ); //o.pulse -= saturate((purePulse - _PulseSize) * _PulseSpeed); // pulse major o.lighting += pulse ; // pulse minor //float innerPulse = saturate(dist - (_Time.y - 0.5 - _PulseStart) * _PulseSpeed ); //float innererPulse = saturate(dist - (_Time.y - 1 - _PulseStart) * _PulseSpeed ); //pulse = saturate( innerPulse - pulse); //o.lighting += pulse * 0.5; // pulse vertex offset //o.vertex.xyz += 1 * v.normal * saturate((innererPulse - pulse) * 0.2); //o.lighting += saturate((innererPulse - pulse) * 2); // player Light float playerLighting = (1- saturate(distance(_PlayerPos, o.worldPos) * .15) )* 0.6; o.lighting = max(o.lighting, playerLighting); // edge of the world float edge = distance(o.worldPos, float3(0,0,0)) - _EdgeDistance ; edge = saturate(edge * 0.07); //test //o.lighting = downLight; o.lighting += _MainColor; o.lighting = lerp( o.lighting, 0.5, edge); return o; } fixed4 frag (v2f i) : SV_Target { // sample the texture fixed4 light =float4( i.lighting,0); return light ; //fixed dist = distance(_Pos, i.worldPos); //return dist; } ENDCG } } }

Went into autopilot last night and started building up the materials in Substance Designer when I remembered the point of this model was to learn nDo/dDo. Anyway will be a useful point of comparison with how far I got.

My little game (the mobile one) is coming out in the next couple of weeks :D

Made a quick LED shader for Unity

Been making a Chiappa Rhino whilst taking HoudiniFX for a spin.
