The higher the factor, the 'bumpier' the texture appears. If your image has an alpha channel, but is empty, you won't see an effect.ĭetermine the strength of the bumping by adjusting the Bump Map Factor. If the texture has no alpha channel, the shader converts the RGB channels to an alpha channel. If you want to use the image's alpha channel to control the bump map, activate the Copy Alpha to RGB option so that the texture shader calculates the alpha channel instead of the RGB values. To activate the bump map, select Enable in the Bump Mapping options of the texture shader's property editor. If you have a render region open, you will notice that the texture has been applied to your object.
