Object correction (strange looking glass)

It can happen that transparent objects are displayed a bit weird on renders.

This situation occurs when normals of the transparent object-oriented inward, so Photo-Tuning engine cannot calculate glass material correctly.

To solve this difficulty normals of the object need to be recalculated and then flipped to achieve the proper orientation

Example of a shower screen:

You can solve this issue with the Modify object function in the Sani menu.

In the modify object window, first select recalculate normals, set Smooth threshold to zero and click on apply.

Second, select flip faces and apply.

The render after correction:

If this doesn’t work, try to reduce the reflection of the object. In menu View | Material select the object material and then reduce the reflectivity in the parameter menu on the right.
