Uses ISL by OnoSendai to Choose from one of 12 different brick textures, with corresponding bump and exponent maps. The textures are randomly mirrored on both X and Y axis to create a non-repeating high definition texture.

For this to work with a placeholder texture in SketchUp you set the 'OverallScale' to the number of bricks wide your placeholder is and set the 'AspectRatio' as a multiplier of the width... so for a 10x10 brick placeholder you just set the 'OverallScale' to 10 and the 'AspectRatio' to 1
