Is it possible to set shader uniform parameters right before each node is rendered?
Or does the engine need a OnPreRender callback for that?

So you need to recalculate the value of the uniform for each node, each frame?

Well, for some nodes yes.

If I understand you correctly, currently it's not possible. You can just change the material uniforms before you call the render method. But while it's rendering the complete scenegraph, you can't change them. If you just wanted to change the material uniforms, you can use the setMaterialUniform function.
