Put one down, scale the text to fit the frame, and move it to one corner or another. You can do this interactively by putting the cursor in the viewport and hitting ϽenterϾ. Be sure to turn off the “Center Text Horizontally” toggle, or else the text will reposition itself on each frame, which is jarring to watch.
Consider this SOP chain: If we lock node D, then nodes A, B and C won’t be cooked. So we can unload their memory, since it is serving no purpose. You can also use the M/m options of sopcache to force unloading after a certain memory threshold is reached. And there is a -U option, to control the unload 54 (Continued) For more detailed information, open a textport and type: help sopcache And now, we can up the ante in the next tip. | SOPs: THE FOUNDATION OF HOUDINI flag behavior of SOPs. You can use this to just force all SOPs to unload via a script command.
Triangulate 2D The Triangulate 2D SOP is extremely useful for dividing a surface into irregular triangles, such as you might want to set up a piece of cloth for DOPs, or for setting up some terrain before using the Fractal SOP on it. But you can improve the results by using the minimum angle parameter – that’s what it’s there for. A long skinny triangle will always have a really small angle somewhere inside it; by requiring that all triangles have angles of at least 10 degrees for example, you can get rid of the skinniest ones.
