alpha channel woes
hi trying to work in chapter 10 - it says to work with the alpha channel and to select it and render a lighting effects filter to get a stone look... that filter is greyed out when i select the alpha channel... any insight as to what i am doing wrong? thank you. |

Re: alpha channel woes
The alpha channel is used to store the bump map that the Lighting Effects filter will use - you can't render Lighting Effects onto the channel itself. Make sure the main RGB channels are selected, not the alpha channel, when you come to apply the filter. |
