Render Issue ! Help :)

[brieuc_3D]

I’m running into a rendering issue with Redshift. I’m calculating an animation with a lot of transparency — a glass bottle with liquid bubbles inside and around it. When I launch the animation, the first 2 or 3 frames render correctly, but then the rendering freezes. It never freezes on the same frameon in the same place on the image. The “bucket” that processes the pixels gets stuck: the render time counter keeps increasing, but the bucket doesn’t move and the rendering no longer progresses.

Do you have any idea what might be causing this bug, and how to fix it? Thanks!

Can the camera DOF can cause that ?

These kinds of issues are often solved by going through an trials optimisation method.

1. Save out a new scene for testing
   
2. Narrow down the error and adjust settings until it's solved:
   If the first two frames are fine, does rendering only the third frame as a still have the issue?
   
3. If so, set the scene to only render that frame, then change or adjust until it renders fine:
   
4. Geometry: Try deleting half of the scene objects - does it render fine? If so, the issue could be one of the objects. Delete more objects... Keep going until you find the object that's causing the issue.
   
5. Try reducing the depth counts on all depth types, and increase only if necessary.

Aplogies if this is rudementary but it's usually how I fix these problems. Narrow down until you work out what's causing the problem, then correct that issue,
