Solaris and Karma » Why Thin wall has more noise?

Whenever someone compare renders like these I just don't get it, what is the point you are trying to prove here?
That an almost 10 years old render-engine is faster than a not even 2 years old one?
Karma is a baby compared to how long RS has been around, plus Redshift sucked at retractions for a long time not sure why you aren't willing to give Karma the same patience. Should we compare Redshift 1 to current Karma XPU to see what happens?

I'm not saying that Karma shouldn't improve, it stills lacks a lot of common-place functionality but it's getting there and fast! also we should celebrate all the good things that's doing better than other render-engines, crypto mattes? incredibly fast to render, volumes? a breeze to setup and render, Volumetric lighting? a dream come true on how easy is it to use, Supporting USD features? better than anyone, I could go on...

I don't have no patience. The reason of I recalling this problem is that the same problem has been present throughout mantra's entire lifecycle.
I don't want to see it happen to Karma again.

The thin wall in Redshift has not this problem. Karma really needs some optimization about sample algorithm.

I want to know why the bubble warp example is so slow in karma (about 30 mins). It only takes several minutes in RS.

This usually happens because the edit LOP is higher up the LOP node chain, and when you change something in the Edit LOP, all the downstream LOP nodes also have to recook, resulting in slower interactivity. Do you still see this issue when the Edit LOP is the node with the display flag? A video (or better yet a hip file) could really help clarify the issue, since I have often used the Edit LOP and the performance is generally pretty good...

I uploaded the video and hip. The mouse click lost in lop viewer randomly.

Hi,
Same sample count in karma. But the Thin-Walled material has more noise.
What is the reason? How to reduce them?

Thanks!

Hi,

I use Edit lop layout several boxes. I found that dragging object in Edit lop is not smooth as object context.
There are 0.x seconds freeze when I click mouse for selecting and draging.
If Houdini could improve the interactive performance of edit lop it will give a better layout experience.

Thanks.
