Version 3.08-RC1.1 Tweet

[albatetra]

Hi Aoktar,

I've installed the update and used in production with no major issues so far, up to today, when I'm rendering a simple animation involving VDB.
After a random amount of frames (can be 10, can be 100 frames) machine freeze for about 30 seconds. Once it unfreeze I inspect the log (I've cleaned it before the render start) and I can see these never ending list of errors:

.....
.....
another 200 lines of the same errors on various devices (I've 4 GTX1080 in my system).
If I hit render again nothing happen. No rendering. I've to close C4D and re open it and keep going with rendering.

Any idea ?

Thanks

Does Octane for Cinema 4D support input projection on osl texture yet?

I tired using a modified version of osl flakes but can't get the input projection pin to show up like in standalone. (see osl code pasted from osl forum below)

I cannot know reason of Cuda Errors. But we can wish an investigation from Otoy guys if you send the scene. But error should be reproductable.

So Octane v4.0 is here (for Windows users). How long will it take for the plugin to make use of the new features?

I don't have any idea about V4 and plans of Otoy. So i don't have answers yet!

[albaglib]

a real problem for otoy ... it does not even communicate with plugin developers ... for me Octane 4 have no interest if there is no plugin

No doubt a question you hate Ahmet and I don't normally ask, but do you have an ETA on the plugin with OSX compatibility now that RC1.2* has it? Are we talking days or weeks?

EDIT: I mean RC2

I have a problem to compile it for R19, I'll make a release when I sort that. Matter of days.

aoktar sorry to repost but would you mind adding my OSL projection request to your next release please?

This is not a thing which can be answered by me soon, sorry!
