Grille's and Taillights

Before modeling the grille's and the taillights we first take a look at a reference image, like this one. Focus on the black grille's and the tail lights, because we are modeling these in this section of the tutorial:

Nice reference image of the rear grille's of a Lamborghini Murcielago

We start with the first grille. Create a SDS rectangle with dimensions U=4 and V=4. Rename the object to Grille_1.

SDS rectangle with U=4 and V=4 added

This grille is roughly shaped like a cube with tilted sides (well very roughly..).  First move the edges that bend the grille. Because the blueprint lacks this level of detail, you need to closely observe the reference images and estimate the shape and position of the edges.

Move these edges

Then in Edit Points mode, move the points to match the shape as in the reference photo. Probably it will be helpful to switch to OGL (shaded) display for this. Then in Edit Edge mode select the top edge row and set Edge Sharpness to 'Semi Sharp'. When done, move the object in position.

Select the top edges and set them to Semi Sharp

Then we have a second Grille, just above the license plate area. This object is also created from a SDS rectangle. This time use U=2 and V=4. Rename the object to Grille_2.

Grille_2 starts as a simple 4 by 2 SDS rectangle

Then take a top view and align the Grille_2 object with the rear bumper area.

 
This object needs to be aligned to the rest of the rear section and you get this! (top view)

Next select the lower points and move them outwards (see reference image and next screenshots for the required position). Then also select the top left point (vertex) of the object and also move it in position:

 
Select these and move outwards to cover the indentation                                                       

Next, select top left vertex and move it!

Now switch to Edit Edge mode and select all edges, except the ones on the mirroring axis. Set Edge Sharpness to 'Semi Sharp' and then extrude the selected edges just a little backwards (to the inside of the car).

Select these edges, set them Semi Sharp and extrude them

Make sure the mirroring axis is at X coordinate 0,00 and you're done!

Three Grille's ready!

Then it is time to model the taillights. We start with duplicating the Rear Bumper. Rename the duplicate to Taillight. You have seen the trick before: add faces by extruding them and modify the shape in Edit Points mode to match the blueprint.

Faces added to the duplicated object, points moved in position

With these faces still selected, invert the selection (press Ctrl + i key) and delete the faces you don't need. Then for clarity change the color of the remaining faces (we chose red):

Remaining faces colored red

Make sure all points are in the right place. Then add in Edit Edge mode add faces, like shown in the next two screenshots:

You start like this...

and add faces like this!

Then, to finish it all off, switch to Edit Edge mode and select all outer edges and, like you did with the Grille's, extrude  them backwards (towards the inside of the car). Then set these for these edges the 'Edge Sharpness'  to 'Sharp'. And this concludes this chapter! :)
