Hi all,

I've been testing Karma on my Mac and I seem to run into an issue where the render time will slow down to a crawl when my mac turns off the display after 20 minutes or so. For example, I had frames rendering every 3 minutes and then after the 7th frame, the 8th frame would take 40 minutes and continue to grow in render time.

I was able to solve this by preventing the Mac from turning off the display and staying on for the whole render.


Is this a known issue?

Ok I seem to have figured it out. There seems to be an issue with the Hybrid rendering option in RS at the moment. The CPU buckets are occasionally producing brighter squares.

So I turned off Hybrid Rendering and now the buckets are calculating correctly.

Strangest thing is that hybrid rendering seems to run slower. You'd think CPU+GPU = faster??... something seriously wrong with that at the moment.

Hi,

I'm encountering an issue with Redshift running in Houdini 19.5 for Apple Silicon Mac Studio Ultra max spec.

Renders are producing randomly brighter buckets on certain textures in scenes. Attachments to illustrate one such scene where a rock texture is giving a random artifact within the bucket. Other textures within the bucket don't appear brighter.

Bucket size for this scene was 256. 512 buckets will occasionally hang for too long so I've opted back to 256 even though it is slower.

Is it a texture caching issue between the GPU and CPU?

Anyone know what might be causing this?
