ShaderFrog specific uniforms do not have a default value when exporting as THREE.js

[zya]

For example:

Exporting this shader: http://shaderfrog.com/view/35 Will result in:

{
  "id": 35,
  "name": "Oil or Fire",
  "fragment": "...",
  "vertex": "...",
  "uniforms": {
    "time": {
      "type": "f",
      "glslType": "float",
      "description": "",
      "textureId": null,
      "runtime": {
        "texture": null
      }
    }
  },
 .....
}

It would be good if it (uniforms.time.value) had a default value of 0.5 for example. So it would work straight away when imported to a THREE.js application.

Good call! Out of curiosity are you not using this runtime library to load the shaders? The runtime.updateShaders call is what passes the time uniform automatically to all shaders. I still think this would be an improvement either way.

@DelvarWorld No, I am not using the runtime library. Was just trying to load the shader in an existing THREE.js application.

Seeing this as well. Is this project still active?

[AndrewRayCode]

I am not actively working on this project, but I have nebulous plans to revisit it and improve everything. I think a clear improvement would be to ditch the runtime all together, and just export runtime code that will properly create the Three shader material

Cool. I think both could be useful. Enable raw shader loading without the runtime, but then use the runtime to expose the shader parameter tweaking, maybe with a UI like the 3js gui stuff. Also, I would change your pricing model. I don't think the monthly subscription model makes sense, but I'd gladly pay/donate ~50-100 bucks outright. That said, I did manage to fix my issue mentioned above with some judicious use of the chrome debugger. This is a cool project and definitely bridges the gap between shadertoy, and less technical programmers doing three.js stuff. I'd be happy to help you out w this if you're interested.. Cheers!
