OTOY Forums

I am having several issues first what I get in the Live viewer is not replicated in the final render - the final looks horrible compared to live viewer

I do have only resend updated objects checked and send materials every frame

2cd) I was using 2.11 and it was rendering frames fine though wrong
switched to 2.14 and it took 2 more minutes to render the first frame then it started having failures and spitting out frames in 3 seconds with a lot of errors in the log

I have C4d 16 with 3 Nvidia 980's 36 gig of ram

I know I am rendering to a bigger size to the final over double the size but its really blurring out and the lanterns look totally differnet

Also in the live window it says 4068 mb of ram / 2356mb used and 35mb free those don't add up shouldn't I have 1700+ mb free ???

So Questions
1:) why don't the renders look the same
2:) what are all the errors in the log
Can't connect node 'RGB Image' (NT_TEX_IMAGE, 0000003B9BB8AEF0) to static pin 'unknown' (P_UNKNOWN, type PT_UNKNOWN) of node 'Surfboard' (NT_UNKNOWN, 0000003A8B105380)

ESPECially

CUDA error 719 on device 2: An exception occurred on the device while executing a kernel. The context cannot be used anymore and must be destroyed. All existing device memory allocations from this context are invalid and must be reconstructed.
-> failed to bind device to current thread
device 2: failed to initialize resources

3:)Is there something wrong with my cards ?????

4:) Why are the renders taking longer that the last version of octane ? I thought you spend up the 980's - last one took 10 min ----2.14 new version took 12 mins then failed ?????

Hi,
first you should read faq for getting some answers. About "horrible", i think do you mean black background and pixels on edges. Check alpha channel option and test it in photoshop. It should be well.

Errors,
some of them is harmless and about node connections. Maybe a few mistake on plugin. But, last error shows the exceed you vram memory. As you said that your free ram is 35mb and near to zero. Can easily go to zero on bigger output and final render.

About performance questions, follow standalone release topics. They are writing what's changing on each versions.
