Yep that's the one. So it's a bug or just that it has a downside?

HF1. It happens in the simplest of scenes too. I'll do a video today

Has this issue been addressed yet in the latest release?

hi all
why when i activate the volumetric fog from the coroan sky, does it show up as a white band in the VFB?

i realise hte latest daily may not have addressed the issue of the slowdown - but wanted to confirm and let you know i installed it and its still slow.

I use a TR - could it be that?

I cant sorry - however i can confirm it does it with all scenes.
Thank you for the videos! We will see if we can reproduce a similar issue. Is there a chance you could share your scene with us?

Hi Devs
3 videos comparing 07.30 daily, 10.23 daily and Corona 12HF1. You can see the FPS difference. On the latest daily, even on my other monitor, things like youtube start to stutter which indicates to me it interferes with the GPU somehow?
All in all, the latest dailies are much slower - the IR buckles the PC (not just corona).

i was using max 24 - its not a max 25 issue. definitely a corona issue.
Oh, I reverted everything back to 12 HF1. Everything is fine now. It was like few ms lag on everything, orbiting, moving mouse, changing values.
If you are getting this kind of viewport lag/stutter for example when panning or rotating, it is most likely a 3ds Max 2025 issue. It happens with any renderer, even when Corona and V-Ray are uninstalled. I was also unable to reproduce it in 3ds Max 2024. This is already reported to Autodesk.
If you are getting something else, please do let us know. As Aram said, a scene and a video demonstrating the issue would be perfect.

its for maps that are NOT square. For instance, a floorboard texture that is 2000pixels x 800 pixels. It adjusts the ratio so that it maps correctly.
Hi.
I'm not sure if I understand this update:
"Extended CoronaBitmap about togglable aspect ratio lock button + added 'Fit to bitmap' button. The second one is available when Real World Scale is on and lock is not active."
What's this for? Triplanar?

just in general - while rendering, the VFB seems more laggy. Even in windows in general - browsing the net, the websites feel laggy to (ie mouse stutters). It just feels really off. It never used to do this. I am using a 5995wx TR if that helps.
Something feels off with this release. As soon as i launch a IR render, imy system becomes almost unusable. everything seems more laggy.
Is this happening in any scene or only in some specific scene(s)?

Any update Tom?
Things are awfully quiet around here lately :)

Hahaha well the community is unanimous in wanting that roadmap updated! I hear y'all loud and clear :) Definitely this week, hopefully tomorrow (the 25th). I am just getting confirmation from the devs on what is looking like it ought to be in, and what still has some uncertainty so we won't talk about it yet to avoid disappointment (of course even the things that do get listed are still plans and not promises - all is on track for now with what will be on the roadmap, but the nature of development is that can get unexpectedly derailed at any time).
I am looking forward to letting you all know about our plans!

probably worth a try - i havent tried yet but will later this evening.

Here is an extract from the page:
"So, what the heck is GPU hit test?
When navigating the 3ds Max viewport, 3ds Max often needs to determine what is underneath the cursor.
For example, in 3ds Max, when you hover over an object, it shows the object’s name under the cursor. When zooming or panning, 3ds Max must calculate the cursor’s 3D position. Similarly, when selecting an object or sub-object, 3ds Max needs to determine what is underneath the cursor.
This process is called hit testing. 3dsMax cast a ray from the cussor point and detect that the ray hits. So, as you can expect, the more object and polygon you have, the more time
Around 3ds Max 2014, when the development team was focused on improving hit testing performance, they created a GPU-based version of hit testing. However, this approach had some issues, and since 3ds Max still had a software driver mode that relied on CPU hit testing, the team decided to improve the CPU version instead. Eventually, they achieved similar performance with the CPU, and the GPU version was gradually forgotten.
However, the code for the GPU version was still present, and it could be enabled using Maxscript.
Now, in 3ds Max 2025.2, there is a bug in CPU hit testing, and enabling the GPU version can be used as a workaround. Interestingly, after a decade of GPU advancements, it also appears to deliver better results."

probably not a popular opinion on what im about to say - but the latest VFB, for me atleast, is slower. I used to be able to copy and paste the render (while rendering) and paste it into photoshop. It was never so laggy. Now, its extremely laggy while rendering. I find the tone mapping setings are also.
