Had done these a while ago with SophieH, but unfortunately we had some conflicts in building it (Sampler2D isn't allowed in the lighting graph,...
DX7,8 -> Fixed Function Only Old DX9 -> Vertex Program Only (Shader Model 1 emulates this) DX9 (ATI 9500 or more recent) -> SM2, SM3 if available...
Actually, Unity's CG can't compile lower shader model programs, and will only compile fragment programs to a minimum of PS2/VS2 (SM2)- The shader...
The CG-Compiler actually handles that simplification, similarly the glsl pre-optimizer will catch the unneeded registers and combine them. So...
Either the Splat, Split, or Swizzle nodes let you access components directly- That said, internally everything will always still be represented as...
Another important note, on the lowend iOS devices, you should try to ignore the normalize, pow, log, and other nonscalar math nodes. Pow in...
There are a few solutions for the too many interpolators issue. Using the "uv" parameter from a sampler uses up an interpolator, if your reading...
Howdy WarpedAxiom- Had originally made it as a 3D pathfinder for open-air pathing (Birds, flies, similar airborne particle type agents) so I...
Been playing with some attempts at blind (That is, no pre-computation) pathfinding. After having come up with a fairly efficient way to interior...
Neptune_Imaging: A while back I'd posted this image, but it seems to answer your question, so I'm throwing it up again. In the event you need to...
You should simply be able to ignore it- The compiler will (for the most part) remove what your not using. If your unsure if it was properly...
Yes, but the preview will not display. Instead, export the shader, apply it to an object, and when you want to see your changes, re-export (This...
bb0x, WorldReflection with a normal input requires the shader to include the "INTERNAL_DATA" block to perform additional transformations in the...
Firstly you need to be using Unity Pro to be able to display the preview- That said, if you for some reason close the window, there should be a...
Olly: This issue is related to the target shader model and is really a variant of the "Too many texture interpolators" issue, should be solvable...
Howdy KFR, I wrote this effect back for Unity 2.6, as of Unity3.0 there is an official Godrays effect you can find under Assets -> Import Package...
From his project file, it's the SSDO technique from GPU Pro It's setup to be only d3d9 (presumably with ARB's constant limitation), but if you...
It will build the permutations of the shaders that use light-mapping for you, from Albedo (Similarly, if you don't use albedo, you will see the...
[attach][attach] Nothing particularly complex here, in the first example, feeding it to emissive to make it clearly visible (whereas, feeding...
Ah, sorry about that. When I originally authored that graph, it was for atlased textures, in which the frac is necessary, however frac can bring...
