Question on programmable shaders

Unity Engine
1

Hello,
I have a question regarding a problem of an application I was doing in Unity. I am using programmable shaders for my model to make some interactive slicing.
I did the app on Powerbook Mac with Unity3D free version. It works like a charm on my MAC, but I have a problem displaying the shader(the famous magenta color on my model) on PC!
Any idea how to fix this?

Thanks in advance,

You need to get a new computer and a current version of Unity.

What kind? GLSL probably isn’t going to work for you on Windows.

Yes, I am using GLSL. Do you know how to fix this? And if I get the Unity Pro version, would it make a difference?
Thanks,
Miro

Read the first bullet in “Preliminaries”
.

Not at all. GLSL and Windows don’t mix as far as Unity is concerned.

It’s generally best to work with the latest version of Unity, but if you’re programming in GLSL, then the update won’t help. You will either need to write in Cg, or add the -force-opengl parameter when running the player on Windows.

Very helpful link… As it states “Note that GLSL shaders cannot be used in Unity applications running in web browser on Windows.”
Does this mean that GLSL shaders will run on Windows in Unity stand alone apps? Do you know any work around the problem of running it in the web browser?
Thanks in advance,

Don’t support Windows.

or

Write only in Cg.

or

Write in Cg, and put a GLSL SubShader before the Cg one, if the autogenerated GLSL isn’t good enough. Then, report a bug, because it’s intended to always be good enough.

Thanks,

Can you write a little more on the line above? What do you mean write CG and put GLSL SubShader before the CG one?

You can see the GLSL that the Cg->GLSL converter barfs up by hitting the “Open compiled shader” button in the Inspector, with the shader selected. It is unreadably ugly, with a lot of redundant assignments, parentheses, and the worst variable names ever. However, you can refactor it if you can’t tell what it’s doing.
