Analysing Frames - Render Issue

[pavlovgg]

Hello,

I have a problem with rendering in the Picture Viewer in Cinema 4D R16, on Windows 8. Everytime I try to do a final render, on most scenes, I have a delay that lasts for hours. In the progress bar it says 'Analysing Frames [1-1[ completed: 0%'. Cinema 4D becomes completely unresponsive and after a long wait I always have to force close it through the Task Manager. The Octane Live Viewer, on the other hand, responds quickly and doesn't crash the software, and that's how I've had to render still images up untill now.

I am using the latest version of Octane.

Any ideas how to sort this out?

Regards

It's active by default and new option to detect which objects are needed to be movable. You can change by Geometry Control in render settings. Try Manual assignment. But what kind of crazy scene causes this for a single frame? Do you have some massive particles or uncached dynamics?

Okay, after some testing I noticed the problem is in the Render Settings - > Octane Renderer -> Geometry control -> Auto Detect

When this is enabled, it causes the initial freeze and consequent crash. The setting has to be switched to Manual Assignment. But then things like HDRI environment light will not update.

The scene contains scattered grasses and trees, using Carbon Scatter. I guess the instances are uncached until render time.

Not sure how to fix the light issue now, I'm not very well versed into the manual assignment control.

"HDRI environment light" not requires any object tag or this option. But movable or animated geometry requires Object tag if you don't use "Auto Detect" option. Do you know how or why we use Object tags?

[aoktar]

It's not related with this option. You select floatbuffer and it produces "Linear colors" not tonemapped. If you don't know or no need it, stay with "Float tonemapped" buffer.
Last, please watch our tutorials for differences of this options.

Sorry, I have no idea. I've bought Octane a few days ago. I applied object tag to all the objects in the scene, but nothing changed.

Update: Okay, I'll just read and check the tutorials on this now. I used float buffer after watching another tutorial.

Update 2: After enabling Float (tonemapped) everything works correctly. Thank you!

I'll be happy to reply all question but i don't have much time. Could you please watch first quick start video and render settings and object tag tutorial. It will give much idea about renderer. Then we can help better.

Regarding the "Analysing Frame" issue, I've noticed this happening when I'm working with large geometry caches, e.g. a 1000 frame Alembic cache. If the update is set to check automatically for changes, it will go through all 1000 frames of that cache every time. This, of course, is not ideal. Changing it to manual and just adding an Octane Tag to the Alembic object works, however.
