I have an Nvidia 5080, 16 GB, and I use "Filtering"...
The screen is disgusting, full of white dots.
It's very disappointing!!!
Are you sure that the 5080 is actually being used? Which filtering settings are you using?
I'm attaching my filtering and the system I use.
I've been using it for years.
I may be wrong.
Sorry, that should have been progressive rendering. And are you sure Iray is using the GPU - check the log (Help>Troubleshooting>View Log File) after a render completes (just do a sphere primitive as a quick test).
Have you tried an actual render?
It looks like you have limited lights in the scene, and then it will take longer to converge.
Honestly, I don't know what to answer anymore ^^
Confirming that your card is being seen and used would help.
By your screenshots you are rendering with Daz Studio 4.24, and Blackwell 2.0 GPUs (RTX 50xx series) are not supported there, so you are rendering on CPU.
Split to its own thread as the one you were posting to covers Daz Studio 2025, which is what you need for 50x0 support. It appears you are in fact usign DS 4 and that is your problem - you need to be using the Daz Studio 2025 Alpha for rendering to enable your GPU.
In the filtering screenshot above, I noticed that firefly filtering is turned on. By any chance is that the same firefly that Poser uses as a render engine, or is it related to that? Or, is the term firefly simply not at all the same as Poser's?
It’s not related to Poser at all.
Fireflies in this case refer to white pixels that sometimes appear in a render.
Many thanks to Richard and Stefan for helping me.
I followed your advice and everything is working very well.
Forgive me again! I'm having a lot of trouble with Alpha.
Many materials aren't compatible, the camera rotates strangely, and my shadow rotates forward.
What should I do?
And what did the log file say? Help>Troubleshooting>View Log Filke.
Camera behaviour away from the origin has been odd, this is a known issue - generally a sliught zoom with the mouse wheel straightens it out. If that isn't what you mean then please give more exact details.
Actually, Richard, the camera is completely dependent on the frame (I used a red arrow).
There's a light that rotates before the frame, so the camera naturally goes into unwanted rotations.
I have to adjust my camera manually.
It's not practical at all and unfortunately very restrictive.
No, it is very hard to work with - one work around, if possible, would be to move the whole scene so that the camera is more-or-less in the middle. As I said, a quick zoom in and out also seems to make the viewport match the camera view again, though that is going to add trial and error to the process. Daz is aware of this, and as far as I know sees it is an issue that needs addressing.
