  • Issues with static raycast accelerator

    Hi,

    I recently encountered a problem with rendering ocean. Especially on shots where you can see far into the horizon, some frames take up to 6 times longer than others to render.
    While the rendering itself is pretty fast, the part of "Building static raycast accelerator" is what seems to makes the difference.
    Its just weird, that it only occurs on some frames and not on others and all the render nodes have the same amount of RAM available (32GB).
    I think it only started when I upped the skyline subdivisions to get rid of the noisy horizon and I remember Ivaylo mentioning, that you fixed something regarding the horizon subdivisions in a recent nightly build, so maybe you could tell me in which nightly build this was fixed, so I know if I´m simply missing the update or if its some other problem.
    Dynamic memory is set to half of the render nodes memory (16GB), but since default geometry is set to "static" this shouldn´t be an issue anyways, right?

    just a quick update, seems it only happens on 2 of the render nodes, so I´ll have to do some more testing whats different with those...

      the horizon management was changed two days ago in order to improve it and to make the simulator-extension blending better, and now the simulated part is subdivided too.
      it's possible that you are using very high subdivision count and this causes huge ram consumption. this should be not a problem now, the subdivisions are optimized

        Yeah, I need to update to the lates nightly soon...still waiting on some renderings to finish, don´t wanna update in the middle of a rendering...
        In the problematic shot skyline subdivisons were at 8 I think, which greatly helped with the noise at the horizon, you think that was too high?
        Or can I now use such high subdivisions with latest nightly?

          the latest nightly you can subdivide up to bigger values, as i remember 20 was the limit on my machine, now it can be bigger. see the video that i just posted in the images section, it is made with the new horizon subdivision method
