And to get decent performance for 10000 shapes you need to use a fake molecule. You can use a marker set which can have spheres and cylinders connecting spheres. Each marker is an atom and each cylinder is a bond. Each marker has an id number which is its residue number, so you can color marker 57 with "color :57 gold". Markers can be read from an XML file or made from Python.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span><a href="https://www.rbvi.ucsf.edu/chimerax/docs/user/markers.html" class="">https://www.rbvi.ucsf.edu/chimerax/docs/user/markers.html</a></div><div class=""><br class=""></div><div class=""> Tom<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Feb 26, 2021, at 4:30 PM, Tanmoy Sanyal <<a href="mailto:tanmoy.7989@gmail.com" class="">tanmoy.7989@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Hi,</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">I have a bunch of shapes (spheres and cylinders) created through a .bld script.

It is possible to set the colors directly in the .bld script, but I need to make an animation out of this. E.g: if my .bld script contains lines that draws shapes like so:</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">.sphere 0 0 -1 5.0</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">.cylinder 0 0 0 1 1 1 1.0</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br class=""></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">I want to be able to later have a bunch of scripts called 1.cxc, 2.cxc, 3.cxc, .... each of which change the color of the sphere and cylinder.
