We can now edit the material properties of the glass and add texture to it. Selecting glass as our material for the sphere. Then specify the material of the sphere to be glass.
Then go to the material pallet and add the glass material by loading it into the scene as seen in the gif below.
Now that everything is set up we can make soap bubbles real by downloading the soap film texture (or use any image you want). And make each bubble unique using the transformations. Copy, transform and merge the same bubble. In order to get many copies of the sphere you can use many transform nodes. Just throw a uvtexture node at the geometry and add a material node right after it. Luckily, we don’t have to manually input each uv coordinate. Adding a light source makes looking at bubbles more fun.ĭon’t forget to add a remesh node to the sphere in order to break the primitive down to an actually vertex representation fo the sphere to use textures on. 4 spheres in time without any material yet. You can move the light using a transform node or directly in the scene view. We have also added a point light at the upper most layer of the network for later shadows. Here we took one sphere and create many transformations from it together with the $F parameter to animate the transformations. Lets take some spherical geometries to apply the texture to. Texture (left) to triangle (right) mapping. The triangle in between the vertices will then receive the image enclosed by the uv coordinates. You can imagine uv coodinates to be a 2 dimensional vector attribute of a point that locates the vertex color by pointing at the coordinates inside a square texture image matrix.
Textures are usually mapped to triangles by specifying the uv coordinates at each point. We will want to project the following soap film texture on to the surface: Just a jpg file. You might have had to deal with minimal surfaces before, and for that purpose we will try to create soap bubbles. This is the result captured in a video with a little less light.

We will explain how to create an image as the following one: Soap bubbles in front of a metal wall. This is effectively a tutorial about editing materials. We are going to see how to add a texture with transparency to your surfaces. Click here to get to find a link to the Guided Houdini Files.
