Question

` the shader tutorials on the doc not working take look

so i follow the doc to make my first shader and when i did run the code
the code didn’t change the blue color value

do you plan to run that code on editor or runtime?
if you want it to run on editor while you edit your shader, then you will need to use @tool

@zdrmlpzdrmlp

runtime

at runtime

[zdrmlpzdrmlp]

ok i know why, it’s “blue” not “Blue”
change it to

self.material.set_shader_parameter("blue", blue_isnot_value)
