Testing some shaders. Trying to convert a plasma GLSL shader to unity.. not working properly yet.
\n(and still looking for a good shader tutorial for beginner..: \/ )<\/p>\n
The main code should be under fragment shader I guess..(?)
\nThe original GLSL shader doesnt give any error in Unity, but I guess you cannot view those shaders in editor?
\n(it says: no subshaders can run on this graphics card..)<\/p>\n

\nNow I got the main code as pixel shader,
\nmuch better, but still not same as original..<\/p>\nHad to add line “#pragma target 3.0”,
\nwithout it you get error “Instruction limit .. exceeded; .. instructions needed to compile program”<\/p>\n
