Hi,
I've released Cheetah3D 8.0 today. I can't belief that v8 actually made it over the finish line. You can find all the necessary information about v8 on the following page:

Thank you very much to all who helped during the Alpha and Beta test. :) :):)

Kind regards

Brilliant news!! Thanks for all your hard work.
 
Using C3D8 nearly every day I have nothing to report, very stable so far.
The M3 Pro MacBook is a beast, Falcon rendering on CPU aside Cycles on GPU works without much throttling, fans at full speed of course.

I figured that out, but I need all my old files to open without this enabled (it is just annoying to have to turn it off for models that don't have PBR textures, of which I have a ton).

A preference toggle to always open a file with PBR shading turned OFF would be great.

Hi Gavin,
sorry for the late reply. Once you've turned OFF PBR shading in the 3D view you can save this setting into your window layout. The next time you open Cheetah3D it will remember that setting.

Old scenes should look quite OK under the PBR renderer. If a scene looks wrong under v8 please let me know. It might be a bug in the new Metal 3D viewport.

Bye
Martin

So there is no fix for the green screen bug? Bummer - i really need the uncompressed render..
Apple M2 Ultra - Sonoma 14.4.1
 
Yes, this one #130
Rendered Animations appear fine in the Render Manager Thumbnail - but when saved out in everything BUT H264 - a green background appears. The H264s will work - just feel better about using uncompressed. I havent tested - but im guesssing maybe it is because i dont actually have a white Object as the background - just using the layouts 'background color'
 
I still can´t replicate this. I´m not sure Martin is aware of the issue nor an macOS update fixed it probably. I´d do a test on your side to verify.
PS: Martin did run tests from what I read but thought the M3 might be the cause.
 
it may 'fix' the issue but it will only cause new problems. In some cases I will need rather large Backgrounds to cover the area - and this will end up blocking my HDRI. But - yes I will do a quick test when I have a moment. I do have an update I will also install for Sonoma (14.5) - thanks.

Hello,

As mentioned in a few responses to the original observation of the trouble in comment #130, said trouble seem not to be a C3D issue, it seems to be an MacOS issue.

Cheers,
gsb

I've had the same problem, last time it was in a reflection.
 
Test complete. no luck. Updated my OS (Sonoma 14.5) installed Pro Video Formats 2.3.1... rendered with a white card Background - still green screen. rendered with a Yellow Card... the solid Yellow still had the strange 'modeling' pattern... the products highlights (whitest areas) were green.
 
I just upgraded from 7.5.1 to 8.1.1 a couple of days ago. I am on an M1 Max Mac Studio (2022), macOS 14.5. I've noticed dragging UV maps with a split screen is very laggy. When I drag the UV map in one pane, it takes half a second for the other pane to update. It was very smooth in the previous version, no lag at all between panes. This is VERY annoying. The more I use this new version, the more I'm tempted to go back to the old one. Can I open 8.x files in 7.x?

It's not just UV maps. Any time two or more panes are open, there's always a significant lag updating the non-active pane. If I drag something, it jumps around, failing to keep up. This is very annoying.
 
Hello,

There is a good chance that I may not be understanding the setup of the window that reveals the trouble you are having.

FWIW, I am _not_ running an M series Mac

If I have a file open, working on an object with 10,000 polygons, using the default UV Editing layout, which has the UV pane on the left and the modeling pane on the right… selecting and moving part, or all of the UV map works smoothly with no delay in updating the model window.

But, as I wrote, I may not be understanding the totality of what it is you are doing that results in slow updating…


Perhaps you could post up a simple file with an object that is having trouble, along with a screen shot of your window pane layout for testing by others.

Thanks and cheers,
gsb

It's not a particular file or window arrangement or action. It's every file every time the view is split. To reproduce: create a new file, add a primitive (e.g., a sphere), split the window into two or more views (e.g., camera and front), drag the object. The object drags smoothly, but updates in the other view lag and the movement is jerky. Sometimes the delays are minor, other times there is a significant lag between doing something in one view and the other view updating. I'm not sure if this has to do with the number of polygons being drawn or the action being performed or whatever.
 
Hi John
:mad: I can not reproduce the problem with extensive lagging / jerky redraws when dragging an object.
This is a mildly complex model (DNA replication on the leading strand of a DNA helix), using a window containing 3 panels of the view-port (perspective, left and camera).
Animation - polymerase generates new base elements to build up the split DNA - works smoothly in all 3 panels.
As gsb, I am running an "ancient" Mac with Intel.
