Black screen, no vray

[Jelena2 (Jelena)]

when i open my rhino file the screen is black and doesn’t let me click anything

-tried to look at plugins on a blank document, under ‘Plug-ins that do not ship with Rhino’ there is ‘Vray for Rhino’ and a folder ‘Vray for Rhinoceros VRScene Importer’

-if i turn these off my other file does open, but then i do not have vray as a render option and need it asap!!

all was working literally this morning and then i saved it and shut the file, reopened after lunch and didn’t work

[Japhy]

please run systeminfo in the Rhino command line and post the result.

[Jelena2 (Jelena)]

of the file i changed the plugins on, or the file i can open without vray operating?

[Japhy]

Ideally not in Safe Mode (no plugins/graphics driver loaded) but that works as well.

[Jelena2 (Jelena)]

ok this is for the file I am working on but turned off the two plugins so that i can open it

Thanks, I was thinking might be running on a inadequate graphics card, but that looks ok.

With the battery unplugged make sure its using still using the performance settings…

Soooo, you bought a laptop with hybrid graphics and rhino doesn't run right. READ THIS

Hybrid graphics laptops are more and more common if you buy a consumer grade machine. (I recommend buying a mobile workstation for professional modeling but these hybrid machines are quite prevalent in the consumer market, especially for students.) They tend to generate a TON of tech support here because of the way they are set up from the factory. Hybrid systems are built with 2 graphics processors. A low power graphics chip (typically Intel HD or UHD) and a high power graphics card. However…

[Jelena2 (Jelena)]

i had it to high performance already, just changed the ‘ open gl rendering GLU’ and the ‘power management mode’ to max performance

still doesn’t work when i open the file

-not sure if it’s anything but when ive tried to open it a few times it says ‘searching for 29’ in the bottom left in a green loading button and that’s when it seems to stop loading kind of
sometimes has it sometime it doesn’t have it

[Jelena2 (Jelena)]

this is a pic of what it looks like, can’t type can’t click etc.

[Japhy]

This might be related to vray material assets being searched for. Are any of them networked?

Have you tried troubleshooting by exporting selected portions of the model? Import these into a new file set to wireframe.

[Jelena2 (Jelena)]

sorry i suck with technology- what do you mean by the materials being networked? how can i check that?

i can also try the second thing if the material thing doesn’t work

[Japhy]

Resources that are on a networked drive, not on your hard drive.

[Jelena2 (Jelena)]

i don’t use a hardrive so i think they are networked then, i just download things from chaos cosmo and then use them or from websites like ambient.com and save them to my folders

[Jelena2 (Jelena)]

the file has just loaded​:heart_eyes:
everything is working but when i try do a quick interactive render is says ‘failed to find a default viewport to render’
don’t wanna close it and then it not open again…
any idea what i can do
if not will accept my fate

Dear Jelena, hello.

Please share your issue via our contact form
We have met similar cases, but needed is to collect the version information and more which will be requested later.

Waiting for your ticket in our system.

The most probable reason for the problem is that you have lots of Cosmos materials in your file, and you moved to another machine, or the texture cache is cleared.
The green bar at the bottom that @Japhy is probably reading as V-Ray searching for asset, is actually Rhino searching for the textures for the viewport preview of the cosmos materials.

It can be because of two reasons:

1. Cosmos assets are not available on the local machine, but Rhino doesn’t know that (yet) and it is doing its best to find the textures to display them. If you have a lot of network-ed files, that could take a while and will happen every time, unless you have the files locally
2. Cosmos materials use .tx files which Rhino does not support, and we need to sample them with V-Ray to a .jpg file that Rhino understands. Depending on the texture sampling settings, this may take a while, but happens only once, as the texture cache is local to the current machine. You can significantly speed up any future samplings if you lower the sampling resolution via vrayTexturePreviewSettings command.

The error you see when rendering is probably due to the fact that you started the render process before the viewport is created (e.g. while it was still black). If that was the case try to render another viewport.
