anbt 5 Posted March 26 I would like to have light 1 from frame 1 to 10 and light 2 starts at frame 11 for example. Cheers Share this post Link to post Share on other sites
anbt 5 Posted March 26 thinking of setting keyframes on the intensity/exposure I suppose 1 Share this post Link to post Share on other sites
Vinz 9 Posted April 3 (edited) There is a 'Switcher' node at object level that is normally intended to switch between cameras but it may help you organise the keyframing in one location. Also the display frame range can be expressed as so: $F<=10 for the first light and $F>=11 for the second light. If anyone knows how to express portions of time/frames (ex: activate between frames 30 to 40) I would be interested too.. Edited April 3 by Vinz Share this post Link to post Share on other sites
Atom 1,234 Posted April 3 (edited) I think you can extend it like this... ($F>30) && ($F<40) Edited April 3 by Atom 1 Share this post Link to post Share on other sites
Vinz 9 Posted April 4 Thanks Atom, this will help also as I am looking at creating a strobe light effect.. that is to say, a light comes on every other frames/time. I need to find out what expression could translate that.. Share this post Link to post Share on other sites
Atom 1,234 Posted April 4 Here is a basic chops driven sample hold. For redshift light instances, you can control the brightness by supplying an additional attribute along with the s@instance. //s@instance = "/ob/rslight_spot_SOURCE"; v@light_color = set (rand(@ptnum),rand(@ptnum+801),rand(@ptnum-311)); ap_chop_hold_lag_drives_light.hiplc ap_rs_colored_instance_light_circle.hiplc Share this post Link to post Share on other sites
Vinz 9 Posted April 6 This is all really cool.. your strobe effect is nice and quite organic.. I tried to get something more mechanical and fast (1off/1on) but it still feels like it cycling trough.. I tried to use 'pulse' chop Also I could throw a 'rand' directly in the light color channel which I didn't know about Thank you for the light point instancing trick.. will surely come very handy Also I tried to hack the parameter interface of the light.. these are locked right? Thanks again ap_chop_hold_lag_drives_light_1.hipnc Share this post Link to post Share on other sites
