Hello,when I learn the caustic optimization and render a picture,there is a warnning,but i can't find where to add it,warnning is here:
WARN main [AdjointIntegrator] render(): forcing 'evaluate=true' since multi-pass rendering was requested.
Where could I to force it?

There is nothing to do on your side. The warning is telling you that it had to change/force evaluate to tTrueotherwise it would not have been able to continue. This usually happens if you're rendering with a high sample count per pixel. If you're usingmi.render, unfortunately, there is no way to set evaluateon your end, it is set toFalse` internally.
