Rhino 8 won't open some files and others opening slowly

[Japhy]

Did you get a chance to try Nikolay’s suggestions?

@Nikolay

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.

If you isolate a small sample we can take a look here as well (sans 3d party plugins)

Oh, this worked. I had my assets in my office server, but once relocated it to a local folder, the file opened faster.
Thank you.

Update:

This is still taking a lot of time, even after moving my assets to a local place in my drive. I’ve test this in rhino 7 and it doesn’t have this problem. It just stays there searching for embedded files…

Sometimes, i just press cancel and the files open but in wireframe? maybe is the initial mesh shading that it’s taking time??

UPDATE 2:

I just move the rhino file, and opened it from my local drive and it opened without trouble.
I work from shared server in my firm, this has never been an issue. Maybe rhino 8 has trouble finding textures/meshes on servers?

UPDATE 3

Files still take it’s opening locally, and the common denominator is rhino trying to find textures in heavy models. Sometimes i keep pressing esc to cancel the initial meshing and open in wireframe.
