Vectorworks Rendering Briefing Doc
This document summarizes key themes and advice for achieving realistic renderings in Vectorworks, based on the provided source.
Main Themes:
No Easy Button: Achieving photo realistic renders in Vectorworks requires patience, trial and error, and fine-tuning numerous settings.
Beyond Default Settings: Default settings often require adjustments, particularly for lighting, texture quality, and background integration.
Realism over Speed: "Final Quality Renderworks" is generally not recommended, favoring custom settings or Redshift for better results.
Lighting is Key: Realistic lighting, including ambient occlusion, indirect lighting, and color temperature, is crucial for avoiding an artificial look.
Texturing Matters: While tedious, applying detailed and realistic textures is essential for achieving visual depth and authenticity.
Important Ideas/Facts & Quotes:
Rendering Workflow:
Start with low DPI on Sheet Layers for quicker test renders before increasing to 300dpi for final output.
Use custom Renderworks settings, starting with "Medium" and adjusting based on the specific scene.
Lighting:
Ambient Occlusion: "Adding some Ambient Occlusion will help a lot, shadows tend to 'collect' in corners and Ambient Occlusion mimics that effect."
Indirect Lighting: "Also make sure that you have Indirect Lighting established to catch realistic bounce lighting."
Color Temperature: "Viewports and Cameras behave much more like actual cameras than eyeballs and you have to specify what color temperature will be rendered as 'white'." Adjust the white point in Lighting Options to match the scene's light sources.
Texturing:
Reflections: "Try adding some subtle reflection shaders to your wood and concrete textures. […] You'll want to keep the Reflection % fairly low and/or the Blurriness % on the mid to high side to prevent straight mirror reflections."
Glass: "Your glass textures are reading as too 'cloudy' and not reflective enough. […] I change the Reflectivity shader to Mirror instead of Glass." Consider using a Transparency of 95% and adjusting the Index of Refraction for the rendering method.
Wood: Native wood textures are often criticized, requiring careful attention to grain direction and repetition.
Backgrounds:
Shape: Apply backgrounds to curved surfaces for a more natural panoramic effect, avoiding distortion on flat planes.
Distance: Increase the distance between the background and the scene to enhance realism and minimize distortion.
Glow Shader: Add a Glow shader to the background's Reflectivity, mimicking the brightness of daylight. "Outdoor scenes with daylight are usually much, much brighter than interior lighting." Start with a Brightness of 200% and ensure "Emit Light" is checked in both the shader and Indirect Lighting options.
Additional Notes:
The example provided reveals a tendency to over-brighten the background. Experiment with image effects on the color shader to control exposure and contrast.
Reflection intensity should be carefully controlled, especially on complex untextured objects.
Overall:
Achieving realistic renderings in Vectorworks requires a deep understanding of the software's settings and a commitment to experimentation. By carefully adjusting lighting, textures, and background elements, users can overcome the software's limitations and create convincing visuals.
When making textures, I try to start with images that have a solid background so it is easy to set a transparent color. This way I can make sheer fabrics, bead curtains, and layers of textures that produce shadows without having to render tons of geometry
ReplyDeleteVery good, makes perfect sense. Having unnecessary geometry hurts in many ways. Thanks for your input
