I am design an 3D model. I am looking to sell it on unity asset store. I was using unity built-in shaders for my model. Now i want to sell it, can i sell my model with unity shaders or i need to write own shaders for my model. There is any license issue with selling of my model with unity built-in shaders?
You do not even have to include the build in shader. Since everyone has the build in shader they are already there if a user imports your model.
If you have a modified version of one of the build in shaders , you can include them into your package without a problem.
