STEP BY STEP PAINT AN EX­IST­ING IN­FRA­STRUC­TURE

01SUBTLE TEX­TURE GEN­ER­A­TOR FOR A ROAD CAM­BER

Us­ing the Line tool, build closed splines around the ar­eas you would like to de­fine as a cam­ber to the road and road edges. Edit the spline with the ver­tex, seg­ment and spline selections un­der the mod­i­fier stack and cre­ate as many closed splines as nec­es­sary for de­fined ar­eas. Add an ex­trude mod­i­fier to this. Open Prop­er­ties and untick Ren­der­able. Name the ob­ject.

02 ROAD TEXT AND LANE LINES

In the Shapes panel choose Text, type the road text and add an ex­trude mod­i­fier. Us­ing the Line tool draw dashed road lines, chevrons and park­ing spa­ces. Un­der the mod­i­fier list ex­pand Ren­der­ing and click En­able in Ren­derer and En­able in View­port, se­lect Rec­tan­gu­lar and set length at 1,000mm and width at 100mm. Open prop­er­ties for both ob­jects, untick Ren­der­able and name both ob­jects.

03 PO­SI­TION THE TEX­TURE GEN­ER­A­TORS

Once all of the ‘non-ren­der­able’ ob­jects have been cre­ated they must be po­si­tioned cor­rectly so that they in­ter­sect the road sur­face.

In this case we have a pla­nar poly­gon ob­ject. Move all the ex­truded lines and ob­jects up or down such that they in­ter­sect the road, and you can in­crease their ex­tru­sion val­ues if nec­es­sary.

04 SET UP VRAY­DIS­TANCE­TEX

Se­lect a V-ray ma­te­rial and choose Com­pos­ite for Dif­fuse. Cre­ate two lay­ers. For Layer 1 choose Vray­dis­tance­tex. Click ‘in­side sep­a­rate’ and ‘in­side solid’. Choose a tex­ture map for the ‘far’ slot. Add the road lines and ex­truded text. Type a dis­tance of 50mm or smaller. Re­peat with Layer 2 and make it an Over­lay layer. Add the shader ob­jects, change the in­side and near colours and make the dis­tance larger.
