Rhino Render Window Doesn't Pop Up

Rendering
1

I’ve been wanting to render my model however every time I hit the render command or even render preview the render window that usually pops up simply doesn’t. My whole viewport gets frozen and I can’t interact with the objects or even type in commands nor can I save the file so I’m scared to close it. The only thing I can do is manipulate layers. I have up to date drivers and do have intel denoiser installed. I’ll attach what I’m seeing in a screen recording. I can have it sit for an hour and nothing changes. Am I just being patient or is something wrong?

From a quick look in the debugger it looks like the RDK (renderer development kit, part of Rhino) is taking a long time to prepare the data in your file. I’ll gather info and create a YouTrack issue for @andy .

Hi!

I’ve spent quite a bit of time looking into this model and it has helped me make quite a few improvements to Rhino. However, one thing I haven’t solved yet is that for some reason, the displacement (object properties displacement) on the tree object that is inside the “TREE TRUNK” block never actually completes…it just waits forever.

This doesn’t matter much in the display, because the displacement is done on a thread - so it just never shows up. But the renderer actually waits for the displacement to complete - so it just sits there forever.

To get this model to render much more quickly, you should edit the TREE TRUNK mesh and remove the displacement modifier from it.
