Keyshot Basic
- Hardware notes: Keyshot use CPU to render, and the speed increase linearly according to core count:
- Basic Workflow
- Import Geo
- assign material (to research, apply material by scripts)
- assign HDRI lighting
- tune lighting and rendering setting
- render
basic task - Place Logo
- Use label on the applied material, with color and bump texture option, you will get a good logo look on your existing material ready model
- advanced tutorial (showing your material < label < label material type of combon): https://www.youtube.com/watch?v=Lu1xTYYC-Mg
basic task - batch switch material
- duplicate a copy, and right click and choose material > change material type
basic task - animate material
To animate color
- right click on the color attribute and and choose animation and set it up
To animate visibility (not opacity): so no need post compositing for already confirmed animation
- animation wizard > Fade > choose parts to fade; or choose parts > right click > animation > Fade. done
basic task - quick post color variation
- click the edit pen icon in the final render viewer:
basic task - custom reflection
- click on environment HDRI to open HDRI edit, and create new HDRI with dark color, then use pin to create custom light shape to create desired reflection
Keyshot Material Example
Cloudy Material / Translucent material / semi-transparent materail (like paper, thin plasic)
- render setting:
- self shadow: on; global illumination: on; ground illumination: on;
- material setting:
- Advance material type >
- Specular transmission (amount of refraction related) setting to control transparency.
- Specular color (reflection color cast, Black = no color cast) to control look casting color and strength of reflectivity
- Roughness of Transmission: control internal structure roughness, basically disturb the refraction and give a blur look of refraction - “cloudiness” look
- Roughness: control the surface roughness, basically disturb the reflection and give a blur look of environment reflection - “Glossy or matte” look
- Diffuse color: color of object itself and strength of color compared to its reflection/specular color
Back-lit material
- create a light object with Point Light Diffuse Material
- Power and Color: control light intensity
- add glow post-effect:
- Camera > Effect > Bloom (Glow) to add glow boost intensity and radius (highlight part blur)
Glass material
- Glass (Solid) Grey: (type: Basic > Glass Solid)
- texture option = only Refractive Index + Roughness
- (type: Advanced > Dielectric) : allow color ramp option mapping to color
- texture option = Transmission + Transparency distance + roughness + bump + opacity)
Keyshot Advanced
version control tips
- to do list
- update geometry
- export material linking list
- automated shot building script and tool
- render layer control
- element/material variation and compositing workflow
lighting control tips
- to do list
- light setups
- reflection tips
- animated environment light
- as environment rotation can't be animated, you have to animate your model and camera together
- animated Emissive geo light
- Insert a plane or sphere and use a translate animation to move across the model.
- Apply an Emissive material to the sphere/plane, increasing the intensity and disable ‘Visible to Camera’ in the Advanced settings.
- In the Project, Setting tab, enable ‘Global Illumination’.

Resource
- keyshot cloud, for tons of material, back plate, environment hdri, textures.
- For cloud resource, use web browser and click download to get special link for the download
- then, use cmd line to bin and run code like this (free login acc required)

Problem and Solution
- Problem: glass render with alpha channel checked, but glass is not transparent in png, still with background behind it
- Solution 1: use glass material with refraction checked on, not (no solid glass, or dielectric or transparent plastic) “because this is the only material rendering with an “alpha channel”
- Solution 2: double render, one with your old glass setup, one with your simple glass material just for the alpha channel, then combine
- Solution 3: render what you have with backplate as RGB 0-255-0, so perfect green screen, then key out green screen in nuke something like that, it may affect other transparent color as well though
