I downloaded a fish model the materials of which had to be changed in blender so it works, then i imported it as another scene into godot so that i can edit it, but seems like i cannot edit the shader because it is not godot shader from godot but i could make a new shader material wich immediately turned the model white then i proceeded to add lines of fragment function to set the albedo according to a custom sampler2d it worked but the fishes fins are only visible from one side as the fins are one sided so there is an inner side presented towards one of the sides. i want to have that inner side visible i was attempting to mirror the normal binormal and tangent in case it is !FRONT_FACING but it did nothing. then i thought maybe i have to alter the light function but i wasnt going into it just yet.
