Hi Anastasiya, Unfortunately ChimeraX does not correctly render transparency when there are multiple transparent surfaces, as mentioned in this previous post: <http://www.rbvi.ucsf.edu/pipermail/chimerax-users/2018-July/000274.html> The post suggests using mesh instead of transparency. With large molecular surfaces, the mesh lines may appear too dense, so you may want to recalculate the surfaces with lower gridSpacing (e.g. command "surface grid 1.5" where the default is 0.5); however, that will also make them less smooth in shape. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/surface.html> If map surfaces (not molecular surfaces) you can show fewer mesh lines by using a larger step value, e.g. commands: volume style mesh volume all step 2 <http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#general> I hope this helps, Elaine ----- Elaine C.

Dear ChimeraX developers,
Hello! Thanks for this amazing tool, I enjoy every second of using it! I have a question about surface imaging: I have several subunits in the protein, and I would like to show surfaces of particular regions of different subunits. However, when one surface is above another, the lower one is not displayed no matter what the transparency value is. Is there a way to display both of the overlapping surfaces?
Thanks in advance!
