Hello, I have multiple cameras in my scene and I want to switch cameras based on the current frame number. I tried inserting this expression in the octane IPR/Output camera ROP parameter, it evaluates correctly but when rendering/using IPR, octane just loads frame 0. I tried it with mantra and it worked correctly.
Let me check it, perhaps the Octane ROP camera parameters are not declared as animated strings. Meanwhile, probably you can use the camera switcher node, animating its parameter using the expression, to have the same workflow.
