How to make sure a single image stays a single image not a sequence?


Recommended Posts



I am loading a single image using File COP and then adding VOPCOP Filter or any other COP for that matter, and when I MMB, I get a sequence which is time dependent. I wouldn't mind this but I want to use Switch COP to switch between the File COP and the other branch which has other COPs.


When I do this, Houdini errors out showing this:




I am using $FF in an expression for the Switch input if that makes any difference?


Any idea on how to fix this?



Thanks :)

Thanks but why are other COPs create a sequence out of a single image? It should respect the input. In my case I want my single image to stay a single image unless I specify a frame range for the other COPs, but I didn't. I couldn't find any option to limit the frame range or force the COP to be a single static time-independent operation.

Are you sure that you didn't kept any time dependent expression in your File COP? You can check it by MMB click on the File COP, it should be time-independent.

If you didn't set up time dependency in your VOPCOP the result also should be time-independent as long as the input is.

Thanks pezetko, yeah I didn't use an expressions in the File COP and it shows as time independent. I see the issue now though.


I am using a SOP node reference to get attributes from it which is time dependent. I now put the same node in the other branch while ignoring its output so now they both work.
