More Cycles Settings
How to adjust the bump-map strength:
The bump map in Cycles is listed under the displacement tab.
As of right now (early May ’11) it doesn’t look like you can load an image as the displacement map, but you can use the standard Blender procedural materials (clouds, marble, ect).
You can adjust the map size using the “size” setting in the image above just as you would under normal Blender Internal, or using the nodes:
So on to the meat of this tip, how to adjust the strength.
Since there doesn’t seem to be a setting for strength, we’ll use a mix node with the displacement material on one noodle-entry and an empty slot on the other:
The ‘mix’ node can be found under the ‘add > color > mix’ option (shift+A). By moving the factor (“fac:”) we can set the strength of the bump map.
Simple and easy! :thumbup:
