GP2 Modeling, Rendering and Compositing Tutorial

After getting the correct values in place I turn on the Fprime 3rd party plugin from WorleyLabs, this plugin renders the scene in real time. Below is the quick render of the object while I am still fixing the amount of lightings, the angle of the camera and focal points.

After making sure I have everything in place, I press enter and create keyframe for the camera. Since I have bunches of renders to do I put the camera and lighting in correct places and created keyframes for all angles. After setting everything in correct places I hit renders on Fprime and save the final render as TIFF.

Since I need to cast shadows on the composited image, I render the shadow separately by unhiding the object from camera and turning on cast shadow. Here below is the shadow cast. After setting this I again rendered just the shadows and save as TIFF. Next step is compositing the rendered images in Photoshop.

Compositing: Photoshop Magic!

Compositing requires a meticulous eye specially if one is to achieve realism. I have been doing digital painting and compositing for more than a decade and had developed this sense. Here below is the process I did for compositing.

I cleaned up the photo and removed the existingcar from the originalby using CLONE STAMPtool. It's in the tool bar menu or you can press (S). First I click the image I want to clone then clone the images on top of the car. I repeated this process until i was able to remove the entire car and I was left with an empty roadtrack. Iwill be using the edited photo to composite the rendered GP2.

Edited the photo a little bit and adjust saturation, contrast and hue to blend with the photography plate.

The scene was rendered in Fprime with alpha channel, this means in the CHANNELS layer in Photoshop I can select the alpha. After selecting the white part I then go to back to layers and select the rendered car.
