[SOLVED]C4D Crash when rendering with Octane and using Takes

[Rev]

Hi there!

I'm experiencing a crash (C4D closes, sometimes the octane.dll crash dialog appears as well) when using the Takes system with Octane.

I suspect this has something to do with octane not finishing generating the materials completely when switching takes.

This crash happens if Octane is told to a render a Take that I have NOT activated once in the viewport - ie, I had NOT previewed it in the view-port during the current session, (thereby allowing Octane to generate the materials).

For example, a scenario - I open a project with 10 takes (I select the takes i wish to render and hit, "render marked takes to preview window" or render all takes). Octane will render the first take fine, and will crash on the second.

IF I preview every take individually that octane will render before (This allows octane to generate the materials in each take) - the crash will not happen.

A crash also occurs if I mark a material NULL (ie "clear material", or set to none) in a take - when that take comes around, Octane will crash.

I AM using x-refs and I think this may be adding to the problem since octane re-generates every material every time a file is opened or an x-ref is updated.

Currently my workaround is to preview every take every time I wish to render - (this takes a while). And I must be VERY careful not to update a material in a file that may be in a take that will get rendered without previewing it. Needless to say, it wastes a lot of time (crashes, etc).

Anything I can do to alleviate this? Thanks!

Hi! Do you want me debug it?

It happened also to me. Try to uncheck "Multi-thread for materials". After doing that I have rendered about 1200 takes without problems.

This was it, thank you SO MUCH! It also helped with random other crashes, I haven had any in a while, where before it was happening 2-3 times per work day. Really appreciate it!

Aoktar, thx for the offer - I tried replicating this in a smaller scene but it did not happen. Will try once more when I have finished the project.
