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.

Examples:

I have also created a short video showing the configuration:

Environment Geometry

On some recent projects I’ve needed to display a vehicle in an HDRI environment only, no backplate.  Sounds simple enough right?  Well, it’s actually not as simple as it sounds depending on which render engine you’re using.  An example of what I’m referring to would be how IRay+/VRed/Keyshot work.  Here’s a clip for reference: https://www.youtube.com/watch?v=jxdtCDfRfTI&feature=youtu.be&t=8m50s

In this post I’ll show you how to setup something similar, but still a hack, in Corona Render. Read More

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.
