I was making a sky shader in Godot, but I encountered an error with the following code:

vec2 sky_uv = EYEDIR.xz / EYEDIR.y;
vec3 Clouds = texture(Cloud_texture, sky_uv * Cloud_scale * TIME * Cloud_Direction * 0.001).rgb = texture(Cloud_texture2, sky_uv * Cloud_scale * TIME * Cloud_Direction2 * 0.0058).rgb;
sky += Clouds;

The error is assignment to function. Can anyone tell me how to fix it?

This line causes the reported error (you can't assign values to functions):

vec3 Clouds = texture(...).rgb = texture(...).rgb;

I guess you erased a variable involved in the second assignment, like:

vec3 Clouds = texture(Cloud_texture, sky_uv * Cloud_scale * TIME * Cloud_Direction * 0.001).rgb;
vec3 Clouds2 = texture(Cloud_texture2, sky_uv * Cloud_scale * TIME * Cloud_Direction2 * 0.0058).rgb;
