[chimerax-users] Movie clipping planes in chimera x

[Tom Goddard]

Hi Greg,

If you save position p1 with no clipping and position p2 with clipping, then there will be no smooth interpolation of the clip planes because the first position had no clip planes.  In order to get smooth interpolating, both positions must have clip plane enabled.

However, my tests were relatively simple and used global clipping only.  Probably there is something specific in your case that does not show up in my simple tests.

Report a Bug and attach it along with a brief description and include your email address on the report to get feedback.  Or, if you want to limit sharing to the few people on our dev team only, you could email it to me.
