Using Houdini FX 16.5.268, created a project with a lot of particles and ran some previews in the timeline, export as alembic to C4D which worked great. However upon re-opening the same project, a "DOP Cook" has to go through all 135 frames and takes a long time to complete.
I'm very recent (noob) to Houdini, and am wondering if there is a way to open without the DOP Cook thing running? I can hit Esc to cancel, but my nodes all appear with red triangles behind them and I'm not sure if this is good or bad (breaks simulation or something not advisable?). Any pointers would be very much appreciated, thanks for your time helping the lesser of us Houdini users .
