I am attempting to use a bump map of an ArtRage layer as paper grain but the tools/paint does not interact properly with it.

Step 1:
Painted a highly textured painted strokes layer using 100% loading and the oil brush.

Step 2:
Exported Layer to channels

Step 3:
Opened a new painting

Step 4:
Loaded as the canvas grain the exported layer's "*_bm.tif" file.

Step 5:
Ensure canvas lighting is on, grain size is 100%, roughness is 100%

The paper's texture appears correct.

Step 6:
Paint with an oil brush known to exhibit texture effects

The oil brush does not correctly interact with the texture: there is NO texture interaction.


I am using ArtRage 5, on a windows 7 icore 7 machine, 2560x1440 monitor
