Gas pump texture

Starting out from the basic model from a previous tutorial, i went into the texturing tab and created a PSD network.

Setting this to include Color, specular and bump.

This transferred three separate groupings within photoshop under those respected titles, ontop of the UV maps created within Maya.

To begin, i added a base coat red over the base layer within the "color" group, saved this, then updated the PSD within Maya.

Using the marquee and gradient tools of photoshop, i created the ridge at the top of the side panels, along with the vents, within the bump layer.

I then used the same method, only via circular marquee and radial gradient to create the rivets and pump holder.

As the rivets, holder, vents and trim look once updated in Maya.

Following this, i masked out areas of the base coat via separate photoshop layers and added the white pannels, the dials text and a base for the rust all in color, aswell as a gradient recession on the dials under the bump layer.

Next i used a textured brush to add rust bubbles, which i then gray scaled into the bump and specular layers.

Then i duplicated the red color group, and replaced the base color with a blue to add variation between the two pumps.

I then repeated this process but with the rust, duplicating the corresponding layers, erasing areas and re-applying the rust texture, simply by hiding the original layer i was able to use the same file, re-saved under another name, to create two variations.
