Trans-Texil VAP Membrane

A collaboration project with cvt engineering for the German company Trans-Texil GmdH, based near Salzburg. We created technical visualisations of the company’s VAP membrane system. Our work involved creating high-quality renders for marketing material used in brochures, website and displayed at Trans-Texil’s booth at the JEC World 2025 tradeshow in Paris.

Process

I started by researching Trans-Texil’s VAP membrane to get an idea of how it works and to accurately visualise the properties. This was followed by creating preview sketches and a feedback loop. I then continued to create 3D previews with different angles, varying colours from the Trans-Texil’s logo and different shapes. From there, one final direction was decided, which became the final result.
For the 3D model, cvt engineering created different quality meshes in GeoDict, which I then optimised, textured and rendered in Blender. It was a bit of trial and error to find suitable meshes to work with, as they were rather computer-heavy. I tried everything from remeshing to baking normal and occlusion maps from high-poly to low-poly meshes. In the end, we made it work.
We also created a teaser animation to demonstrate the potential of showing VAP membrane more effectively. For this, I used simulated data provided by cvt engineering from GeoDict to create and animate water vapour bubbles. This was done by coding a Python script in Blender.
Below are sketches and some of the previews and iterations made.
