(fixed) [HOU-4572] Vray Framebuffer does not appear

[vla_dunev]

On Houdini Houdini20.5.410 and Houdini20.5.445 with the latest nightlies I can't make the framebuffer show (tried reset position, no cigar). The render saves a file out, just no framebuffer.
In my old Houdini19.5.805 with much older vray version all works as expected.

Maybe the root cause is that I've tried V-Ray 7 nightly, which also does not show a framebuffer. Neither does it show any materials, but I'm ready to assume we changed technology in a drastic way and no more v-ray materials in Houdini?


V-Ray Arm version on Mac M1.

Dear vla_dunev, hello.

And Happy New Year!

I just tested the described from you and could confirm that VFB is not showing on MacOS in our latest nightly ARM builds. I will log this now for further dev investigation.
Please choose one of the following builds in order to see and use V-Ray Frame Buffer correctly:

• V-Ray 6.2 release build (December 03) https://download.chaos.com/downloads...-205-62024-adv
• V-Ray 6.2 stable nightly build from December 06 https://nightlies.chaos.com/main#/vray6houdini/stable/6.2/20241206

About V-Ray materials - perhaps you have noticed that Chaos Cosmos (the new official place for V-Ray Material Library) is not present.
Cosmos Mac OS support for the ARM architecture is planned for the future but currently not available, see our docs.

Best regards,
TS

Thanks Tsvetomira,
and Happpy New Year to you and your amazing team!

Yep, going back to the builds you mention fixes the problem in .410.

I wonder if the non-appearing framebuffer points to an incompatibility with .445 build of Houdini? Just mt 2¢.

Thank you for your kind words ")

I've tested with 20.5.410 and VFB wasn't shown. It is not because of incompatibility with .445 build, it is QT related and I pointed out which latest code changes may refer to this behaviour.
We will fix this soon, please just keep in mind that Holiday season is not yet over.

Since the Houdini version is listed under Supported builds when you start the Installer - then V-Ray is compatible.

Thank you for reporting this!

Hi again!

The issue is officially solved in our latest nightly builds for V-Ray 6 and V-Ray 7.
I just tested them - build number # 22827

Enjoy VFB on MacOS with all latest changes ")
