KeyShot Tutorial: How to Render Realistic Ice

How to Render Realistic Ice With KeyShot

The best cloud rendering services provider and KeyShot render farm, Fox Renderfarm will share with you a KeyShot tutorial about how to use KeyShot to render realistic ice.

Tip: To create the ice art shown in the figure, in addition to using KeyShot, we should also know how to create 3D models, using SolidWorks and Photoshop.


Use SolidWorks to create a model. Since we are focusing on KeyShot realistic rendering today, the modelling process will not be discussed in detail.

How to Render Realistic Ice With KeyShot

Import into KeyShot

Open the KeyShot and import the model into the KeyShot by dragging and dropping or by using the 'import' button. We'll see the entire model in white, and open the projects window at the bottom of the interface, where Boaz has changed his name to' glass 'and' ice 'to know what parts he's working on, then select all ice parts, right-click to select the' Unlinked 'related material.

Change the material Of the glass to Solid Glass, and other selections remain the same.

Adjust Material Settings

Next, select an ice cube, assign it a liquid material, set the refractive index to 3, the external refractive index to 1.5, the transparency to 8, and the color to red: 220 green: 230 blue: 255.

The ice will now become clear, but there is still something missing. Looking at frozen ice, we’ll see that it's not completely transparent because when water freezes, bubbles and particles in the water seep into the frozen ice. To achieve this effect, we have to set up bump maps and opacity maps, and we need to create textures in Photoshop. Open Photoshop and create a new blank document that is 5000X5000 in size and has a white background.

Then, create a new blank layer and place it under the background layer. Right-click the background layer, then select 'background layer mask', and click the Add Layer Mask button to set a mask on the White layer. The mask is used because the mask can be modified or replaced all the time without affecting the image layer itself. Next, choose a large multi-Thorn Brush, paint the mask black, and reserve a "frame" at the four corners of the page. Don't worry about the mask being completely black. We finally get a white frame without a background, similar to broken ice.

Save the created file in PNG format, and the texture is done.

Apply Texture

In KeyShot, go back to the material tab in the Project window, click the "texture" tab, select the newly created texture file, set the "bump" and "opaque" textures, and check the "sync" so that if we want to change some attributes, the bump texture will be linked to the opaque texture; the new ice material is complete, and we can save the material to the material library.

Copy and Paste Materials

Return to the 'scene' tab and copy and paste the ice material into the remaining assembly.

How to Render Realistic Ice With KeyShot

Adjust Advanced Settings

The ice looks much better, but it's still not very transparent, because KeyShot renders lighting through materials, so we need to go to the settings options, expand the advanced section, and increase the default number of light reflections from 6 to 12. Don't just increase the number, because some rendering passes take a lot of time. Next, turn on global illumination and, if you like, add a nice dark "illustration" to the scene.

How to Render Realistic Ice With KeyShot

Application Environment

This step requires setting up the lighting environment, opening the library, setting up a beautiful contrast environment, and selecting ' 3 points lighting high 2k'.

How to Render Realistic Ice With KeyShot

Adjust Environment and Camera

Return to the items menu, go to the environment option, and modify the settings according to your personal preferences. Instead of lighting environment, we can configure a color at the back of the model to a cool grey (red: 3. Green: 3, blue: 4), and "ground reflection" can also be checked.

Next, you need to adjust the camera. Go to the "camera" menu, click "+" to create a new camera, name it, and then click "enter edit mode" to set the parameters, including depth of field, according to your own preferences to create a close-up feel. By adjusting the aperture value, we can make objects that are not in focus more blurred but remember not to make them too blurred, just make them look real. When finished, tap exit edit mode and then lock the camera.

Set Realistic Rendering Quality

Next, go to the rendering menu. First, jump to the quality tab, set the quality parameters as needed, turn on sample values to get a higher quality realistic rendering, and increase the depth of field value because we're using depth of field in this scene, and finally, set the 'Ray reflections' to 12.

How to Render Realistic Ice With KeyShot

Realistic Rendering

Return to the output menu, set the image size, the higher the pixels are, the better for printing, and you can get pixels equivalent to centimetres per foot by opening a new document in Photoshop and changing the size setting method. You can also choose to save in TIF format to get an image without a background. Finally, click render and wait patiently. The realistic rendering process may be a little long.

How to Render Realistic Ice With KeyShot

Final Render Realistic

The final effect has come out and it took nearly 10 hours of high-quality realistic rendering. It took so long because of the complexity of the layered transparency, or it could be because the sample values were set higher. In general, Render Time is also affected by the opacity, depth of field, and other visual effects of the assembly.

How to Use KeyShot 9 to Render Christmas Scene - Tutorial
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.!KeyShot 9 Tutorial Christmas Scene Rendering 0!KeyShot 9 Tutorial Christmas Scene Rendering 1Use 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.!KeyShot 9 Tutorial Christmas Scene Rendering 3The 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.!KeyShot 9 Tutorial Christmas Scene Rendering 4Next, 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.!KeyShot 9 Tutorial Christmas Scene Rendering 5Enter 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.!KeyShot 9 Tutorial Christmas Scene Rendering 6Next, 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.!KeyShot 9 Tutorial Christmas Scene Rendering 7Further 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.!KeyShot 9 Tutorial Christmas Scene Rendering 8Add 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.!KeyShot 9 Tutorial Christmas Scene Rendering 9After 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.!KeyShot 9 Tutorial Christmas Scene Rendering 10Next, 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.!KeyShot 9 Tutorial Christmas Scene Rendering 11Next adjust the texture of the Christmas tree.!KeyShot 9 Tutorial Christmas Scene Rendering 12After 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.!KeyShot 9 Tutorial Christmas Scene Rendering 13Use 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.!KeyShot 9 Tutorial Christmas Scene Rendering 14Then 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.!KeyShot 9 Tutorial Christmas Scene Rendering 15Use 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.!KeyShot 9 Tutorial Christmas Scene Rendering 16Next 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.!KeyShot 9 Tutorial Christmas Scene Rendering 18Drag 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.!KeyShot 9 Tutorial Christmas Scene Rendering 20!KeyShot 9 Tutorial Christmas Scene Rendering 19In 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.!KeyShot 9 Tutorial Christmas Scene Rendering 21The 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.!KeyShot 9 Tutorial Christmas Scene Rendering 22To 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.!KeyShot 9 Tutorial Christmas Scene Rendering 23Next, 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.!KeyShot 9 Tutorial Christmas Scene Rendering 24Next, 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.!KeyShot 9 Tutorial Christmas Scene Rendering 25ConclusionNow you know how to render a Christmas scene in KeyShot 9, don't you?
