This could be for a number of reasons, but with limited time to test, I have to assume the following materials are not optimized for re-building with render passes: I rendered the scene in CPU mode and upon compositing the rendered image, there were quite a few cubes that didn’t match the rgb pass. Specific materials do not look correct when composited from render passesĪfter some quick testing, I assigned each non-light material to a cube within an array of cubes.Image adjustments (including denoise and firefly filter) do not affect render passes.Area light reflections – not accounted for in some render passes.I had to switch to lighting this scene with HDRI lighting only as well as swap out some material types to plastic. Both of those posed issues when I tried to rebuild the image with render passes. Originally, this scene was lit with area lights and some translucent materials. I’m hoping they’ll be addressed in the near future. While I can’t say this list accounts for every scenario, here are a few I’ve run into. Some specific materials and light sources cause issues with KeyShot render passes. Unfortunately, I’ve run into a few scenarios in which render passes don’t render out correctly. Below is a list of each render pass available to KeyShot users. Some of them are needed to reconstruct an RGB pass (beauty pass), others are simply used to make further editing of the image easier. KeyShot is able to output a variety of render passes. When you then go to composite them, the composited image may not look correct. Sometimes, render passes don’t render out correctly. Lastly, you run the risk of running into bugs. In order for the compositing to work correctly, these need to be in 32-bit file formats which are also much larger than their 8-bit counterparts. Compositing leads to multiple images being rendered out, which will eat up hard drive space too. It requires you to manually load multiple images and merge them together, a process that is automated with your render engine.Īnd then there’s hard drive space.

For products that must be presented accurately and realistically, artistic license is not helpful. First, the composited result or edited image my not be as truly physically accurate (read realistic) as the final rendering produced by the render engine. While compositing with KeyShot render passes does offer some flexibility, there are some drawbacks. When I hand over a PSD with render passes, it’s easier to use each pass to aid in making selections, masking or adjusting the brightness or color of different parts of an image. The two most common reasons clients asked me for layered PSD (Photoshop) files was so they could place different images within picture frames, or so they could use a rendered product in a number of different pieces of media for marketing campaigns. Whatever your reason, compositing with render passes will usually make the job easier. Perhaps different labels, logos or artwork will be incorporated into the image. You might want to change the color of a background, or easily remove a product from the background of an image.

Who doesn’t like options? The most common reasons someone might want to composite an image as opposed to rendering it as a single still right out of the rendering software is flexibility. Compositing is the art of combining footage from various cameras or render engines to create a complete scene. The two images get combined to safely show our hero in a perilous situation. Then, the actor is filmed hanging off of an 8-foot wall with a big cushion under neath it. First, a video of a busy city street is filmed and this is often called a plate. When you see a character hanging onto the edge of a building by one hand, their feet dangling 200 feet above a busy New York street, Hollywood magic is used to create that shot. Compositing is most often used in the world of visual effects (VFX). Oversimplified, any time you stack up images or videos to make a new image you are compositing. Each vertical slice of this image shows a different KeyShot render pass What is compositing? So, a render pass is an image that, when combined with other render passes add up to the final output of the rendered image sometimes called an rgb or beauty pass. Render passes actually make available to you the results of each of these calculations as individual images. The software compiles the results of these calculations to serve you with a complete image. When you create a rendering, lots of different calculations take place.
