Tasharen Water

[ArenMook]

Ok so fixed it now. What it was apparently was either the ShaderQuality.cs or TWTools.cs script was not present, therefor water was pink

However in my defense i deleted the "Water Example" folder, which those two scripts where in there. If in fact you need those 2 scripts, or one of them, it might be best to move those to the "Water" folder instead, so people dont delete them as i did.

Thanks for you help and hopefully this will help someone else out.

I actually ran into this myself, and it is some issue in Unity. I re-imported the shader and the problem went away.

Greetings, i just upgraded Unity to version 4.5.2f1 (Pro) and now the water is pink. I tried reimporting from the asset store, but i still get the problem.

Is there another way to fix the problem? Is the current version of Unity having issues with the asset?

I was receiving this error:
Shader error in 'Tasharen/Water': 'tex2Dproj': no matching 2 parameter intrinsic function; Possible intrinsic functions are: tex2Dproj(sampler2D, float4|half4|min10float4|min16float4) at line 131

So i fixed the problem by editing the shader in the line 130:

Before:
half3 projTC = UNITY_PROJ_COORD(IN.proj0);

After:
half4 projTC = UNITY_PROJ_COORD(IN.proj0);

[ArenMook]

Hmm... that must be new. You can also resolve it using this then:

1. float3 projTC = UNITY_PROJ_COORD(IN.proj0).xyz;

I have this same exact problem,  I have Unity Pro  4.5  and the Tasharen Water material is pink.   
No errors are thrown in the editor

Update:  The shader fix posted right above my post fixed the problem for me as well.

Hello!

Fortunately, I was able to borrow some smart phones.
So I had an opportunity to test.

However, some device's water was still broken.
This are not texture import setting or build option problem.

All build options are same (Minimum API Level, texutre import setting etc...)

Camera Position (1000,1,500)
Water Position(1000,-2,500)

What version of Unity are you running? Have you tried updating to the latest? I know I had issues with the FOW shaders until upgrading to 4.5.1, and the current latest is 4.5.2.

[MainMe]

Hello

I tested 4.3.1, 4.5.1
but there was not difference.

this problem was influenced by position of camera.(Camera Position (0,1,0) -> Camera Position (1000,1,500))

[ArenMook]

Does it look fine if it's at (0, 1, 0)? What is the scale of your water mesh? The way I normally use the water is I keep its "keep under camera" flag checked so that it's always positioned underneath the camera, allowing me to keep its size relatively small. In Windward I used a scale of (80, 80, 80) for example. Keeping values small is good for float precision.

Hello

All device did not tested.

Model : SHW-M250L
Phone Name : Samsung Galaxy S2
CPU : Samsung S5PC210 Exynos 4 Dual 4210

Camera Pos (0,1,0)
water Pos (0,-2,0)
water Scale (80,80,80)




Camera Pos (1000,1,500)
water Pos (1000,-2,500)
water Scale (80,80,80)

[ArenMook]

Ok, so it looks like the devices simply run into float precision issues. It's likely that they are limited to "half" precision in the shader or something similar. All I can suggest is don't use such large float numbers for position.

[MainMe]

This water seems to unsuitable in android platform.

when camera xz position value is greater than 100,  water occurs problem (even if latest phone model).

Hi Tasharen I am not a programmer so this is proving to be difficult but I am having pink on my sea and I have no idea how to resolve it. I am using Unity version  4.3.4f1 and bought the latest version of your shader in which u mentioned that it is still backwards compatible.
The errors I am getting are

Program 'frag_surf', incompatible types in initialization at line 130
Program 'frag_surf', invalid initialization at line 130
Program 'vert_surf', incompatible types in initialization at line 130
Program 'vert_surf', invalid initialization at line 130

Please help

[ArenMook]

Let me just send you the updated water version I have in Windward right now. I'm guessing you are going down the DX11 route? The one I'm using here locally should work there as expected. PM me your OR# and I'll send you the replacement shader.

Hi Arenmook, I've sent a personal message to your inbox in UNITY with my info , please send it there thanks
