Re: Vray rendering
- Make an omni and place it above the car. Think where and how high you would place the light if the scene was a real studio.
- Turn shadows on, select VRayShadow as the type.
- Under the VRayShadow params, check "Area Shadow." This will turn soft shadows on.
- Select "Sphere" as the type of Area Shadows. The light will now act as if it was a sphere instead of a box (default).
- The U size refers to the radius of the spherical light. Increasing it will therefore make the light larger (softer shadows) and decreasing it will make it act more and more like a point light source (hard shadows).
- Subdivs controls the graininess of the area shadows. You can decrease it to speed up rendering at the expense of quality, and increasing it will improve the quality at the expense of rendering time.
You'll have to do a lot of tweaking in order to get the result you want. I suggest lowering subdivs to 4 (or even 2) to speed things up, as you'll be frequently rendering and re-rendering. If the 8 (the default) isn't clean enough for the final render, try increasing it to 16.
