Version 3.00 - Alpha10.1 (30.04.2016)

Hi Ahmet,

are volume shadows implemented yet? I have downloaded the latest, including the zip files with volume scenes, but I cannot get volume shadows to occur. Everything I do does seem to reflect the same results in your volume scene zip, so I just want to confirm no volume shadows yet.

Thanks!

@Nullifier:
I think you don't mind what happens to render speeds on smaller Step Lenghts. It makes smaller volume steps for dividing volumes and causes higher calculations. After some value your driver and Octane becomes unresponsive due high calculation. There is a TDR topic how to increase this unresponsiveness times.

Thanks for reply, aoktar. I did all that posts were suggesting (change TDR value, update/downgrade drivers, with reboots as well), but unfortunately nothing helped, can't find any solution.
Octane log always returns "CUDA error 719" with heavy scenes. Just want to know if this is something fixable in future releases, or am I the only one having these issue?

Octane log file attached for more details.

It may help to reduce the number of Parallel Samples in your kernel - reduces memory usage. I have seen some instability when rendering massive volumes and anything else going on (perhaps some opencl in the background). What is the resolution of your volume?

Resolution is 29.6MV. I did clean run without any possible background software using opencl, that didn't help. Also tried reducing Parallel Samples. I have attached project file, maybe it would help to recognize what's the reason (test at frames 110-170 where are more volumes). For now, my problem got even worse, it crashes on first samples, while before it could get to 50% at least.
Any help is very appreciated. Thank you.

I've tried to use the "Revert baking" feature and found out that the geometries used for baking don't have normal smoothing applied or exported.
I've tested the example posted by mojave in the "Re: What is "Revert Baking" used for?" thread and everything is fine, but if I try to replicate this in Cinema, I'm getting faceted results.

Hi all! TFD question.
I finished my TFD setup from scratch and works fine in Standard render. I am now trying to get it to render in Alpha 3.1. Nothing shows up in my viewport after sending my scene. My question is- Is there anything else I need to do besides adding an octane ObjectTag to my TFD container? Also, can anyone point me in the right direction with a tutorial or instructions on how to integrate a TFD setup into Octane Alpha 3.1?

Many thanks!

Didn't checked my sample scenes? Absolutely you need an activated density channel in simulation.

Just to let you know, I've reproduced the issue, found the problem and the fix will be released in the next alpha. Thanks for investigating on your end.

That sounds great, will wait for updates. Thank you for help!

I did. It was the "Scale" value on the my TFD container's octane ObjectTag. Under the "Particle Rendering Tab" I had mine way too low, making my density channel invisible. I put it up to about 1000 and it worked like a charm. Amazing stuff!

I'm using a TFD + XParticles + Octane setup and it works well besides a few crashes. Motion Blur in Octane camera will crash me every time. Also, I usually crash when I resend scene to octane if it is right after I cached a TFD sim.

I can't get the new live viewer to show up. It keeps showing the previous version. Please help.
