Shader Error When Build for PS4

[nicolasdai]

Hi, we are facing plenty of shader errors when building for PS4.

Screenprint is attached.

And most of the errors is:
1. ambiguous call to 'lerp'. Found 2 possible candidates: at line 94 (on ps4)
2. Shader error in 'TENKOKU/cloud_sphere': Program 'frag', ambiguous call to 'dot'. Found 3 possible candidates: at line 468 (on ps4)
3. Shader error in 'TENKOKU/fx_Particle': Program 'frag', 'S_TARGET_OUTPUT' is not a valid semantic for varying 'i.color' at /Program Files (x86)/Unity5.5.0f3/Editor/Data/PlaybackEngines/PS4Player/CgBatchPlugins64/include/HLSLToPSSL.cginc(122) (on ps4)

We are now using Unity 5.5.0f3, and Tenkoku Dynamic Sky 1.1.5d

Hi nicolasdai,
I'll take a look at these errors and get back to you soon.

Hi nicolasdai,

I've gone through the shader code and made a few edits that might help.  I'm unable to test directly because I don't have a PS4 Unity license, but I have a general idea of what's going on I think. I'll send you a patch that might address these... though we may need to do a little back and forth to track all the errors.

Hi Viskem,
I never heard much back about these errors and so was not able to confirm whether they fixed the problem or not.  I rolled what I did into one of the recent updates last year so apparently this did not fix all of the problems.  Are you seeing the same exact errors as listed above?  If you see anything different then let me know or post a screenshot.  I will take another look at this.

Thanks for the specific error description.  Is this the only 2 shader errors that you see?  I will take a look!

Hi Viskem,
I just emailed you a patch that I think will fix these issues.  Try it out and let me know!
