How to Create Realistic Pool Water in SketchUp and Kerkythea

In this tutorial, we will show you three different methods on how to render realistic pool water inside Kerkythea. I will also discuss some important points on how to create effective environment settings in Kerkythea. Choosing the right environment setting(s) will enable us to produce such a good-quality pool water scene. For those who don’t know, Kerkythea is a free standalone rendering plugin for SketchUp.

Note: For educational purposes, we will be using the model ‘Mansão moderna’ by Anderson R. Link: 3D Warehouse


Applying Water Texture in SketchUp and Exporting KT XML File

Step 1: Open your SKP model> apply water texture to your pool water model using ‘Paint Bucket Tool.’ Choose any available water textures from the Materials dialogue box. In this case, I will be using the ‘Water Pool Light’ texture.

Use the same Environment Setting and proceed to water material settings.

STEP 1: Search the ‘Water Pool Light’ texture from the ‘Models’ material box> Right Click> click ‘Edit Material’> click ‘Set Dielectric/ Glass’> under the ‘Reflectance/ Transmittance, change the color of ‘Reflection’ and ‘Refraction’ into white> change the IOR value, here I used 1.33 (This is the typical IOR value of water).

Search for ‘Water Pool Light’ texture from the ‘Models’ material box

STEP 2: Adding bump maps to water material is a great way to add realism because bump maps add depth and detail to materials. Under the ‘Bump Mapping’, right click the ‘Texture’> click ‘Add Bitmap’> under ‘Bitmap Selection’ click ‘Browse’> Select the Bump map texture (JPEG)> click OK> type 0.5 value under ‘Bump Mapping Strength’

Under the ‘Bump Mapping’, right click the ‘Texture’
