or choose parts > right click > animation > Fade. done * https://www.youtube.com/watch?v=ferGI5Pkid8 ===== basic task - quick post color variation ===== * click the edit pen icon in the final render viewer: * https://www.youtube.com/watch?v=EYL2u-Q6wY8 ===== 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 * https://www.youtube.com/watch?v=nh1aiursXz8 ====== 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 * tut: https://www.youtube.com/watch?v=heyF-wVVAdo **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) * https://www.youtube.com/watch?v=Np-3e_TthF0 ====== 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 * ref: https://www.keyshot.com/2012/how-to-create-animate-lighting-in-keyshot/ * 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’. * lighting tutorial: https://www.youtube.com/watch?v=upSNlInkSA8 * jewelry lighting: https://www.youtube.com/watch?v=-oduJJ0Gq84 * iphone lighting: https://www.youtube.com/watch?v=XSLQneVyZ4k * bottle lighting: https://www.youtube.com/watch?v=UHlPy61SIwY ===== geo-parts control tips ===== * to do list * quick management tool for show and hide geo parts * scripts to do * copy position tool ===== animation control tips ===== * to do ===== rendering control tips ===== * animation and render advance feature: https://www.youtube.com/watch?v=y49WyMct9CA ===== scripting tip ===== * https://keyshot.com/scripting/doc/6.0/quickstart.html ====== Resource ====== * keyshot cloud, for tons of material, back plate, environment hdri, textures. * https://cloud.keyshot.com * 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) <code>keyshot_cloud_handler.exe keyshotcloud://get?eyJpZCI6MzQ0OCwidHlwZSI6MH0%3D</code> ====== Keyshot learning ====== * official learning site: https://www.keyshot.com/learning/ * https://www.youtube.com/user/KeyShot3D/videos * https://www.youtube.com/user/5ar666/videos ====== 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 * ref: * https://forum.keyshot.com/index.php?PHPSESSID=5e1d7fc7becd65e7730570fc545d2c55&topic=25995.0 * https://forum.keyshot.com/index.php?topic=5613.0 * double render method: https://forum.keyshot.com/index.php?topic=5613.15 * offical guide on transparent bg: https://blog.keyshot.com/alpha-transparent-backgrounds-keyshot * a video explain on reason behind that limit in keyshot (you either composite or use other render): ( Rendering Transparent Objects in KeyShot ) https://www.youtube.com/watch?v=uhud-v4LYoA * composite guide: https://www.youtube.com/watch?v=YoDQ3F9S6s4&t=0s appwiki/keyshot.txt Last modified: 2023/03/15 09:07by ying
