Different results on Android phones

[afk-mario]

Hi! I tried the shader on two different android phones and on got different results, on the top is the unaltered image and in the bottom the altered one.

Samsung SCH-1535 Android 4.4.2:

Samsung SM-G530T1 Android 5.1.1:

In the shader file trying changing

float Epsilon = 1e-10;

to

float Epsilon = 0.0001;

And tell me if that works.

I tried HSLV and HSVA shaders and both had the same result as before on the Samsung SM-G530T1

In the HSVA shader

   float e = 1.0e-10; -> float e = 0.01;

I think everything will get tinted, the question is does it get tinted the same. Sorry, it's kind of hard to debug without the same phone

No problem glad to help!

Same result with:

• No shader
• HSLR shader
• HSVR shader

How is it supposed to look:

Sorry I don't have any other ideas. Without access to the phone there's not much I can do. You'd basically have to comment out 1/2 the shader until you get the same (but wrong because the shader is comment out) results on both sides. Once you know which 1/2 is different then you comment out 1/2 of that etc until you get to the one part that's causing the difference. Once that's found you can try to make a workaround

You're not using giant values to adjust right? Values between 0 and 1 should work. A value like 10000 might not on some hardware.

For example, in the HSL shader, does this at least return the same (wrong) colors on both?

        float4 frag(Fragment IN) : COLOR
        {
            float4 color = tex2D (_MainTex, IN.uv_MainTex);
            float3 hsl = rgb2hsl(color.rgb);
            return float4(hsl, color.a);
            //float affectMult = step(_HSLRangeMin, hsl.r) * step(hsl.r, _HSLRangeMax);
            //float3 rgb = hsl2rgb(hsl + _HSLAAdjust.xyz * affectMult);
            //return float4(rgb, color.a + _HSLAAdjust.a);
        }

If it does return the same colors then check the other half doesn't with

        float4 frag(Fragment IN) : COLOR
        {
            //float4 color = tex2D (_MainTex, IN.uv_MainTex);
            //float3 hsl = rgb2hsl(color.rgb);
            float3 hsl = float3(IN.uv_MainTex.x, IN.uv_MainTex.y, IN.uv_MainTex.x * IN.uv_MainTex.y);
            float affectMult = step(_HSLRangeMin, hsl.r) * step(hsl.r, _HSLRangeMax);
            float3 rgb = hsl2rgb(hsl + _HSLAAdjust.xyz * affectMult);
            return float4(rgb, color.a + _HSLAAdjust.a);
        }

Hi I don't have access to the project or phones over the weekend, will update on monday, thanks for the help.

Is this still an issue?
