I have customized the User0 channel in SP, setting its format to RGB8. Then, using a Filter created in SD, I have stored the four images I need in the R/G/B/A four channels of User0. However, when I export this User0 texture, the content of the Alpha channel is pre-multiplied onto the other channels, causing errors in the other channel information. I would like to ask if anyone has any good solutions.
The file format I used is TGA
