Why Does My Model Appear Semi-transparent?

Managing Metallic and Reflective Surfaces

Written by AryelLast update 5 months ago

With Aryel you can integrate a wide range of 3D assets, but certain models with metallic and strongly reflective surfaces may exhibit a semi-transparent appearance or other visual artifacts.

The property of metallicness is associated with surface materials and is also applied to 3D models. The metallic value can be based on a texture map or represented by a single value ranging from 0 to 1.

This issue becomes more pronounced when the metallic value of a material exceeds a certain threshold, typically around 0.8 or higher.

To avoid encountering this problem, it is recommended to keep the metallic value below this threshold. If the metallic value is based on a texture map, it is important to ensure that the texture does not contain overly bright areas, as they correspond to high metallic values (with black representing 0 and white representing 1).

The problem intensifies when a low roughness value is used, as it results in a smooth and reflective surface. This amplifies the contrast between areas directly exposed to light and those that are not. In such cases, adjusting the roughness value or reducing the metallicness value of the surface material can help achieve optimal visual results.

The semi-transparency effect observed in 3D models on the Aryel platform is related to light sources and the reflection of metallic materials. By following recommended practices such as reducing the metallic value and paying attention to texture maps and roughness, it is possible to mitigate this effect and achieve better visual outcomes.

Our developers are actively working on finding a definitive solution to this issue. In the meantime, we recommend following these precautions to ensure an engaging and high-quality experience.
