Transparency and Set color for Gaussian Surface Visual Model does not work

[Khoa]

• The problem of transparency: after loading a protein structure (pdb file), I create a Secondary structure and a Gaussian surface Visual models on the the protein structure. I then set the transparency for the Gaussian surface, but I cannot see the secondary structure below the surface
• I right clicked on the Gaussian surface and set a color of a constant value. It does not work

Does anyone have the solutions?

Gaussian surfaces may be slow to recompute sometimes (e.g. for large molecules), so there is an "Update" button to recompute the surface. You need to use it when you change the color.

About the transparency: it depends on the order of visual models. Since order-independent transparency is not yet implemented, you will see the secondary structure only if it comes before the gaussian surface (when you traverse the document in depth-first order).

Here is an example with the Gaussian surface first:

And here is an example with the Gaussian surface after the secondary structure:
