BUMP MAP BRICKS

BUMP MAP BRICKS

This material makes use of Poser's bump map facility, combined with the brick node, to produce a nicely textured brick material just using the material node. This material has two unrelated aspects. The first, using the brick node, produces the basic shape. The second, using turbulance and a colour ramp, is used to produce this particular colour scheme, but any other material can be used for the colours.

First, we will deal with the bump map. Here, we have created a brick node, and plugged it into the bump map node. The brick colours need altering to give us the correct image - I have used white for the bricks and black for the morter, to give us raised bricks.

The exact scale of the brick will depend on the size of your prop. Here, I've doubled the size of the bricks, slightly reduced the morter width, and increased the softness to one. This has produced bricks on the right scale for Poser's primitive cube.

Left alone, this will produce very smooth bricks. To get a rougher look to the bricks, I've plugged a noise node into the Brick_color input. The amount of noise has been reduced by setting the Min value of the noise node to 0.8, creating a mottled brick effect.

Now we have our brick, it is time to add some colour. Here, I've created a standard Turbulance node, and left all the settings at their original levels. Next, I've created a Color_ramp node, plugged the output of theTurbulance node into Input node of the Color Ramp.

Finally, I've changed one colour on the ramp, replacing the normal yellow in Color_3 with a grey/ brown colour. This gets us a red brick effect with some darker patches. These colours can be changed to whatever you want.
