KeyShot Tutorial: How to Render Realistic Ice

This article is a 3d rendering tutorial about Christmas scene shared by 3d artist Drown. The article is organized by Fox Renderfarm, the leading cloud render farm in the CG industry. Because there are so many items in the scene, this tutorial will focus on the lighting of the scene and the skills to create a Christmas atmosphere, and the adjustment of the material will be briefly described.Use KeyShot 9 to open the placed Christmas scene, add a camera and adjust the appropriate angle and save. The next work is to give the main body a crystal ball of glass material, and change it to the product mode in the lighting mode, so that light can pass through the glass ball to illuminate the internal details.The tablecloth in the scene and the curtains in the background were selected from red velvet material. The official velvet material of KeyShot 9 was selected to bring out the atmosphere of the Christmas scene.Next, we need to find a suitable HDR map. Because it is a Christmas scene, we need an indoor HDR map with many small bright light sources to simulate the scene atmosphere of the decorative chandelier on Christmas eve. After using the HDR map, rotate it to an appropriate angle to adjust the brightness, contrast, hue, saturation, etc. of the picture to make the scene warm and cold.Enter the image panel, change the image style to photography, adjust the exposure, contrast, etc., to further enhance the warm and cold, light and dark contrast of the scene.Next, open the HDR canvas and manually add a small warm light source to cover the cold-light incandescent light on the original image to further strengthen the Christmas Eve atmosphere. Pay attention to keep the cold light in the scene properly to avoid the scene being too warm. At the same time, the brightness of the small warm light source should be adjusted appropriately and the blending mode changed to ALPHA to ensure that the cold-light incandescent lamp can cover the original image.In order to highlight the crystal ball of the subject, add a sphere to the scene and set the material as a spotlight. After adjusting the position, illuminate the crystal ball.Further fine-tuning various lighting parameters, the atmosphere of the picture is already in place at this time, but now the picture is a little too warm and lacks a bit of realism.Add a cool rectangular light on the right side of the screen to reconcile the warm atmosphere of the screen, so that the screen effect will not be too false. Here we must pay attention to changing the blending mode of rectangular light to blending to avoid the glass ball reflecting pure white rectangular light directly and causing the realism of the picture to be lost.After the atmosphere of the screen comes out, you can start adjusting the texture. Start with the snow in the crystal ball. Use the noise texture node to add bumps to the snow and snow colors on the surface. If the screen freezes, you can hide other items in the scene, including the spotlight.Next, use the matching map to adjust the material of the lounger inside the crystal ball. Anything can be placed here, not necessarily the chair, as long as it is a suitable material and color. It is recommended to use a brighter color scheme to match the atmosphere of the scene.Next adjust the texture of the Christmas tree.After lighting the bulb material on the Christmas tree, observe the current effect. Note that the glass of the crystal ball must be given a transparent glass material, otherwise the light will not find the scene inside the crystal ball and let the light penetrate into the interior scene.Use the matching wood texture map to simply adjust the wood texture base material, and adjust it according to your favorite, such as using a black plastic base.Then open the texture of the glass ball, add the fingerprint texture that is official with KeyShot 9, and after adjusting the position size, turn off the texture repeat, and add the diffuse reflection texture as the fingerprint texture. After that, the fingerprint texture is connected to the label, and the texture is used as the color of the texture. Here, the brightness must be adjusted, and it should be reduced as much as possible to make the fingerprint faintly visible.Use scratched maps, adjust the contrast with color, and control the transparency effect on the glass. Repeat this step to make scratches and bumps on the glass. The effect of the scratches is a little bit, otherwise the glass will look fake.Next use to adjust the texture on the crystal ball name tag.Then use PS to edit a piece of text, pay attention to use a black background, pure white fonts, and use horizontal composition. After saving the black and white picture, use the 3D--Generate Normal Map option in the PS filter to generate a bump texture.Drag the texture to the texture of the brand, create a new texture as the material of the lettering, and adjust the color according to your preference. After adjusting the texture, the black and white image is used as the opacity, and the normal texture is used as the bump. Pay attention to the normal To complete the adjustment of the brand-name texture.Simply adjust the material of the board, and the color matching needs to be darker to avoid the board being too conspicuous. Then use the fuzzy nodes in the geometry to make fluff on the tablecloth. The surface material of the nodes can directly use the original red velvet material.In order to prevent fluff from passing through the model, you can simply render a top view, and then draw a black and white texture according to the position of the item in PS. Use a Gaussian blur filter to blur out the edges of the black and white texture. Then use the texture map as the length texture of the fur node. The length of the fluff where the texture is black is 0. After the geometry node is re-executed, the fluff will not pass through the model.The curtain can use the color gradient node. Change the gradient type to the viewing direction to enhance the volume of the curtain fabric. The background wall is not easy to be too dark or too bright, otherwise the background is too eye-catching and will destroy the atmosphere of the scene.The use of glass as the texture of the candle's wrapping paper can reduce the refractive index to make the texture of transparent plastic wrapping paper. Later, the translucent material is used to adjust the candles, and the color matching can be free.To color various gift boxes, it is recommended to color each gift box, and cool colors are recommended to use blue to correspond to the cold light atmosphere in the scene.Next, you need to adjust the surface effect of the gift box to make the bumpy texture on the gift box. The effect does not need to be too complicated, it can be simpler.Next, add a sphere to the inside of the crystal ball to make a snow effect inside the crystal ball. Finally, fine-tune the composition, lighting, and then render the image.ConclusionNow you know how to render a Christmas scene in KeyShot 9, don't you?

Fox Renderfarm, as the best render farm and cloud rendering services provider in the CG industry, we will often share some production skills and some of the industry's latest and hottest information, hoping to be helpful to your 3D learning. This time we will share how to render the water surface in KeyShot. I hope you like it.Many people think that in the CG production steps, rendering water is a relatively big production challenge. In KeyShot, you can easily and quickly create a real and beautiful 3D rendered water surface. Especially the water texture of KeyShot can help us save a lot of working time, and its liquid map is also very simple.First, create a bump map of the water in After Effects.Start After Effects, create a Composition with an aspect ratio of 2048 x 2048, and name it Noise.Create a solid with the same aspect ratio.Apply the layered noise from the Effect menu to the created solid.Under the Effect Controls tab, change the layering type to ‘Dynamic Twist’, the Noise type to ‘Spline’, check ‘Invert’, adjust the contrast to 55, brightness to -7, and complexity to 12.Click Composition> Save Frame AsChoose a location to save the file, and then click ‘Render’.Tile and blur the displacement maps in Photoshop.Open the Noise file in Photoshop.Under the Filter menu, apply the Offset effect.Set the horizontal pixels to +973 and the vertical pixels to +690.Use the clone tool to clone all the seams you see.Select the layer, apply the Gaussian blur filter, and set the radius to 5.Save the file as a jpeg image format.Create the scene in Maya.Open Maya, create a plane, name it "water", and set the subdivision width and height to 20.Duplicate the plane, rename it to reflection, and move it below the "horizontal" plane.Create a camera>place the camera on the edge of the "water", facing the horizontal line.Change the window from perspective to camera 1, select all geometric figures and zoom in to fill the gap between the two sides.Create a poly sphere and place it on the water.Select the camera, navigate to the attribute editor, and modify the film aspect ratio to 1.78.Before exiting Maya, you need to make sure that every object in the scene has a different material. Create three different ‘lamberts’(luminance units) under the material editor, and assign one to each object.Export the scene in FBX format.Render the model in KeyShotOpen KeyShot and import the FBX file.Using the material editor, drag and drop the water material in the liquid group on the top of the plane.Next, drag and drop the Brick material from the architecture group onto the bottom plane.Click the right bottom plane to open the Brick material option and uncheck the ‘fresnel’ option.Assign a chrome alloy material to the sphere to reduce the brightness of the diffuse color.Under the Project> Camera tab, change the field of view to 1.Use the Environment tab to load HDRI, you can use the "hdri-locations_iceland_4k_hdz" that comes with KeyShot.Under the environment option, adjust the height to -0.400, the size to 8.5850, and the rotation to 21.180.Load the bump map created before, and modify the Scale U and V to 0.180.Under the camera options, turn on the depth of field and use the "select focus point" function to define the focal length of the sphere.Now, click ‘Render’ to see the final effect!Fox Renderfarm hopes it will be of some help to you.

In this article, the best render farm and cloud rendering services provider, Fox Renderfarm will share with you a tutorial from 3d artist Drowm about how to render a teapot in Keyshot 9.IntroductionCreative products are one of the product categories that students need to do at present, so we will render a creative teapot today.Rendering ProcessPrepare the model to be rendered, and then import flowers and plants later and adjust them according to the viewing angle.Import to KeyShot 9.Adjust the aspect ratio and determine the camera.Adjust the attributes and colors of some simple materials in preparation for lighting.Adjust the lighting preset to the product and adjust the image preset to the photography fine contrast.The next step is to start lighting. Add an ambient light and adjust the ambient light to sunlight.Customize the position of the sun, adjust the azimuth and inclination angle to a more appropriate angle.Since our projection was too full before, we need to adjust here by increasing the size of the sun.The whole scene is affected by ambient light and turns yellow and blue so we reduce the saturation of ambient light.Adjust the material of the pot, darken the diffuse reflection of the pot, turn on the highlight to adjust the roughness.Adjust the desktop material. Here, we can use texture noise to simulate the feeling of broken points.Adjust the size and color of the noise, and turn on the highlight to increase the roughness a little.Adjust the texture of the wall and give a map to diffuse reflection. Here, we use color adjustment to make the map achieve the effect we need. Then, reduce the contrast and the brightness.Adjust the wood texture material. Find a wood texture map and adjust the color of this map to make it consistent with the figure.Stick bright yellow wood grain in the same way.At this time, we found that the shadow of the pot was not in the right position, and we adjusted the azimuth of the sun again to make the shadow in the right position.Add a flower model and give the corresponding map file.Adjust the size and position of flowers and plants to a suitable position.Adding a depth of field effect, wherein the focus is the jar, so that the flowers and plants in front are blurred,Fox Renderfarm hopes it will be of some help to you.
