OPEN GL in V25

Tom Krowka — Mon, 06 Sep 2021 21:09:28 GMT

Hello all.......Am running V25...just upgraded. I noticed that in the 3D styles dialogue box (after opening a 3D window) I only have engine choices of vectorial engine and hardware acceleration. Is open GL not available any more? Is my graphics card outdated? Have been running V24 and it still shows up on that version.

Thanks Tom

It has been renamed, since on Mac there is no OpenGL any longer (which has been replaced by Metal). Thus a more general term has been used.

Am running Windows 10, not MAC. What is Open GL renamed to? And how can I determine if it's running in any of the 3D views. Am also missing Cinerender engine both in the 3D views and surface textures dialogue box.

Thanks Tom

Archicad runs on both Windows and Mac, so I guess Graphisoft developers had two choices:

1. Keep calling it "OpenGL Engine" on Windows, and "Metal Engine" or something similar on Mac.

2. Come up with a naming that can be used on both platforms.

So they chose option 2., and renamed it to "Hardware Acceleration".

If you see textures in 3D, you are using OpenGL on Windows since the Vectorial Engine can not display textures.

CineRender was never available in the 3D Viewpoint.

In the Surfaces Dialog, you should have 3 options in Ac25 in the "Engine Settings" field:

Basic Engine
Cineware by MAXON
Hardware acceleration.

Is Cineware available in the "Engine" field of the PhotoRendering Settigns Palette?

Cineware does show up in Photorender settings. Thanks for the info. I thought I had missed something when loading up V25. Tom

Thanks for the explanation and makes sense to align the reference. I’m wondering if there’s also been a change in setting as my models appear jaggy on screen in v25 compared to v24. To test this I created a simple 3D view of the same shape starting a new file from the same templates (only the relevant versions) and noticed that v25 3D views still look much more jaggy edges compared to v24. I just updated 25 to build 4013 to check and it’s still the same. All view settings and overides are exactly the same.

Am I missing something new in v25 to adjust? I've added a side by side screenshot of the simple walls comparing the edges in 3D.

In AC25, is the "3D Antialiasing" checkbox checked in the "Advanced Redraw Options" page of the Work Environment Dialog?

I checked that and it is checked. Set to the same as AC24

Hello! I have the same problem here. The only difference that I saw between AC24 and AC25 is that in AC25 there's no more OPENGL in the 3D Engine checkbox.

OpenGL is now called "Hardware Acceleration".

It does not look so bad on my screen (I do not have a high res monitor).

There is slight pixelation, but it is not annoying.

However if I go into the Work Environment and turn "3D Antialiasing" on or off, I can't tell the difference.

But I don't see any difference in 24 either.

Sorry haven't replied. I noticed an improvement when I set up my preferred Work Environment and brought in some 3D styles from V24. Checking and unchecking the box for 3D Antialisng (Harware Accelerated mode) in the Advanced Redraw Options didn't do much to be honest.

I do definitely see a jaggered contour if I use the template 3D style settings over my own previous settings. The strange thing is if I match the settings of a 3D Style from v24 inside v25 it's not much help but if I import a v24 3D style it seems to help even though the exact same settings are ticked. Quite weird but it at least resolved it.

I imported a v22 3D style and it makes no difference to me.

The 3D antialiasing did not work as well.

Same problem here too. Just transitioned from 24 to 26 and while in 24 the OpenGL 3D window was rendered smothly and realisticaly now in 26 the edges and fuzzines of straight lines is just Revit-isly bad

Check your Work Environment settings.

You need to turn on 3D Antialiasing.

Had this question at the office and solved it by right-clicking on the AC-desktop icon, going to properties and changing the DPI-scale to "System". See attached screeenshot.

Thanks @Gortz !
