yeah hi,
i wonder what it means? in a tutroial it says:
Select the S1 channel and press CopySH to copy this shader.
how do i do it?
If you look at the Material>Modifiers for every material in ZBrush, you will see at the top that there are S1, S2, S3 and S4 channels. Some materials only have S1, and others have different combinations. You switch between channels by clicking the number of the channel that you wish to see.
At the bottom of the Modifiers there is a CopySH button. This will copy all of the information from the currently active Shader channel. You can then select another channel within a different material and use the PasteSH button to replace that channel’s current information with the copied modifiers.
The only material without the CopySH button is the Flat Color material. If that’s your selected material, you will need to choose a different one before you can copy and past channels.
