Cinema4D version 2022.1.1-R6 (Obsolete stable) 08.07.2023 Tweet

It's not solvable. Blender is not Cinema 4D. I don't know how Blender designed and works internally, but C4D has own handicaps to fight!
In C4D, many generator Objects are having virtual Cache and Deform Cache which are generated unvisibly when a deformer assigned. Some are getting re-generated on every small interaction. C4D's dirty flags are not reliable in the cases and object pointers are getting changed. There are not a really working way to know objects are not updated or updated. I spent years to find ways to make it better, it's my best. Tell me if you know better ways to do it superior.

On my scenes I've narrowed the issue to some objects that were causing the issue:
1. Skin modifier
2. IK tag
3. Two Sky objects were present. When OctaneSky was visible and OctaneDayLight was not visible for rendering it caused the restarts.

If I find more I'll let you know.

The "Geometry check" option when rendering in Live viewer is oversensitive. It restarts render without any reason. If a tag or object is being selected in Object Manages it immediately restarts render. It should do this when there is a change in geometry, transform change, material or tag edit etc.

edit. It even restarts when I click on layer names in material manager

It's not like that. There are several effectors, etc. in C4D which are causing update messages. It happens even you click somewhere in viewport or managers. You can check it via default Renderer in viewport. I have many times answered this kind of questions.

Another effector that is very easy to track. Octane area light. When it is present it causes restarts when clicking objects in Object manager. When the light is disabled it does not restart.

Code: Select all

Visible on scattering volumes

is missing in Octane emission in latest R5 build.

why in this version , ican't render finally and don't save my Passes in EXR(octane)
always my render stuck in passes render

i have had this when using custom AOV's / comping in octane, i originally thought it was a deadline issue but turning off "show passes" when doing the final render seems to fix this issue, using 2022.1.1-r4

Good Tip!

Need to watch this a bit longer, but unchecking "show passes" seams to fix this problem!

Thanks

I think you didn't understand the logic and problems on my explanations. Do not spend your time with these, nothing to do on this topic. Just disable geometry updates if you don't want a restart on rendering.

I've tried the same simple scene in RedShift in C4D. Restarts doesn't happen in Redshift the same as in Octane.

Please share your simple scenes, I'll compare with RS

My scene has two boxes, one plane and one Octane area light. This is my simple scene where the issue happens.

We don't this issue with very simply scene like you say. Please record a full screen video to show it

Here is video with the issue and C4D file I used to illustrate this.
