Hello I have a problem this is a bug or not I'm not sure. Here is my problem.

I need to emission switch with normal position but before switch to emission , It show me red mask.


After Switch it , It looks normal like below pictures.


Here is my nodes.


Can you explain that I am wrong in my node or it is bug. Or Is it channel problem.

Hello, thank you for getting in touch and for your support!

Although I'm not quite sure of what the exact issue is, since the screenshots don't reveal all the information required such as the Remap values, I would assume that the values passed through the Add node do not are not within the correct range for the effect you want to achieve.

Please try setting the "Min New" value for the Remap node connected to the Add node's B input to -1, to ensure that when the Float slider value is at 0 it subtracts that value from the gradient extracted from the World Normal Y. You might also have to place a Saturate node before the Emission port to ensure that the value range it receives is between 0 and 1.

Let me know if this helps and, in case it doesn't, please share a sample of your shader, preferably with shader, textures and material, so that I can best help you, thanks!

Saturate solved my problem thanks.
