Super-sampling Problem

R&SIndustrialDesign — Mon, 09 May 2022 09:37:49 GMT

Hello Alias community,

I have another problem with Alias concept 2023.

Similar to the error I already posted (Re: Self Shadow Map Problems - Autodesk Community - Alias) that the "self shadow" is only displayed in the lower right quarter of the screen, it also happens with the camera's image plane.

In wireframe viewport, the image plane is displayed correctly. The moment I activate hardware shade, the image plane is displayed in the lower left corner.

wireframe:

hardware shade with super-sampling:

I found the function which might cause this problem: If a deactivate the “supersampling” checkbox under anti-alias setting, self shadow and image plane are displayed correctly.

Unfortunately when I deactivate super-sampling, hardware anti-aliasing is not working any more. I would prefer 8 x Multi Sampling but there is no anti-aliasing at all. Also when I use the “enhance application” setting in the driver, no anti-aliasing is displayed.

The only way for me is to use software anti-aliasing.

Is there a way to use Hardware 8xMS in Alias concept 2023 and deactivate SS completely?

I am grateful for every answer.

Many greetings,

Guido

This appears to be a bug...I can reproduce it and will report it.

Hello All,

It looks like Autodesk has messed up the entire anti aliasing settings.
If I activate anti-alias settings under wireframe, then this applies to everything. So also for shaded.
I do not like that. It is important to me to only use antialiasing in shade mode and the lines without antialiasing.
Please do not combine, I want to be able to control both independently.
Thanks to all,
Regards,

hello sheyda,
Thank you for your answer. I am aware that supersampling is superior to the usual anti-aliasing methods. I know that from 3D games. Hopefully it will also work in alias soon so that we can enjoy it!
Many greetings,

I would agree that something is very wrong with Anti Aliasing and graphics in general when super sampling is turned on. Sometimes Anti Aliasing fails completely and turning wireframe anti aliasing on and off makes no difference. I have also noticed that if ground plane reflections are enabled when shaded the image jumps to the corner of the screen and all the menus become blank. Turning off super sampling seems to fix this. I am using two different workstations, one at home one in Studio, and they both do the same thing since 2022.2.1 was loaded. the machines have been running Alias previously without these graphics issues occurring.

When the Anti Aliasing fails then a re-boot is the only answer.

Thanks for your report. The issue can be reproduced solidly and it has been reported in our system (ALS-16513).

Hello michael.wu
Thanks for your answer.

I'm glad you brought up the topic.

Would be great to use the new supersampling option with all the features in the futur.
Especially textures are now displayed much sharper!

Top!

Guido
