Corona Paints

I’m often asked for material or scene settings so I wanted to make a post that I can point to in those instances.  This is a Corona Render scene with some updated paint materials.  Some aspects of the materials are from the video tutorials provided by Corona &  Ludvík Koutný.  So, if you want to learn more about how/why I used some of the settings in these be sure to check out their training videos like THIS.

Basic composite workflow comparisons

In this entry I thought I’d setup a basic HDRI + backplate scene in different render engines and start a discussion on workflows.  The scenario is simple, you have a backplate image, and environment HDRI.  You want to incorporate some CG elements into the backplate in one render, compositing not required.  I will provide the files so you can see how the scene is configured & see if I’ve overlooked anything.
So, let’s begin.

Glow/Bloom/LUT/HDR Dome – Corona Render

Corona Render recently released version 1.5  This update included some features I really enjoy.  Glow & bloom functions, ability to add LUT’s, and a dome option in the corona bitmap…map.  Blend all that together and you can get some nice looking images…directly from the render without much, if any, post adjustments.

I have also created a short video showing the configuration:

Speed Shapes

When gathering references for automotive paints I’ve often seen real-world paint samples using widgets called speed shapes.  I created one of these widgets in 3ds Max to help me dial in my paint & powder coating material settings.  I thought I’d share this object in case anyone else out there may find it helpful.

Here’s a LINK to the file.  It contains the object in .fbx, .obj, and .max (2012) formats.  It isn’t a complete scene ready for rendering, it’s just the object itself.  I’ve also included some information in PDF format with size/scale values for some of the various speed shape objects that are available.
