    Default light static or not

    Is there any way to find out what the light is static or not? I mean something like miQ_SAMPLE_MOVING but for light instance.
    I'm doing some parameters caching, but it only works correctly if the light source is static.

    if you mean across frames, we don't have anything indicating that at the current time.

    Is this intended for reducing light sampling noise in animation? We know that for example, if light sampling is low (even medium), and the sample points move around on a large area light from frame to frame, it has a greater chance of presenting unwanted noise in animation. And in fact, can also affect the GI solution. We are looking into this subject.

    No, it's just for caching transform matrix, light spread and other light parameters for every bucket. Because of mi_query and db_access is to slow for call it in every sample.

    Ahh, so you mean moving for motion blur for a single frame. Sorry, I jumped to a different conclusion.

    There may be a way to detect that. Will check.
