Is there good way to generate shaders on the fly? Essentially I want to convert a string to a shader at runtime. Is it possible in JME?

<= here we go!
By meaning of “Generate on the fly”, you think about a Node-base Shader Generation System? …

P/s: I didn’t test the method out, so don’t know what penalty the result can come across… By the way, I’m doing the same things like in the figure 
if you interest!
@atomix Almost, but I want to generate shader source at runtime. Having a java program that generates the shader I want 
You could make your own loader for that, basically assembling the text for the shader when you are asked for a certain file. (using asset manager)
@normen ahh, should have thought of that. Can I change the shader for a material at runtime or do I have to load a new material?
No you have to upload the new shader to the GPU, so basically a new material, yeah.
But that could be done on runtime, get old amterial, get textures ect, then create new, set the parameters from the old and done.
@kwando :
Java program for GLSL shader generation, current NO!
Java program has “texture” making
We have NeoTexture(godlike).
ArtOfIllusion have one
with ability to link directly to a fixed shader!
