Help: Texture disappears in rendered mode after saving file

Rhino
1

Hi everybody,

I have been a long time Rhino user, and this forum has helped me more than once as a spectator. So thank you all for that. But now I have no luck in finding a similar problem on the forum, hence my first post here (yay).

So I am hoping that one of you guys can help me out.

The problem description is as follows:

  • When I create a material for a piece of geometry and add an image ( for example .jpg) as a diffuse color texture it shows fine, until I save the file, close it and open it again. Then the texture doesn’t show in rendered mode. Instead it often shows some sort of standard studio environment image. When I replace the texture with a completely different image file, or change the file name, it shows fine again. Until I save the file, close it and open it again.

As I said: sometimes instead of the diffuse texture image, Rhino shows some sort of studio environment image as diffuse image. Like this:

And sometimes Rhino swaps out diffuse texture images between different materials, like this:

This is driving me nuts. Hopefully, somebody here has a solution.

Hello - I think the first thing to try is to disable the above plug-ins in Options > Plug-ins page and then close Rhino and start it again - is there any difference in behavior?

Hi Pascal,

Thanks for your suggestion, but unfortunately that doesn’t work.
At first I thought it did the trick, but once I opened the file again, the mismatched textures popped up again.

Any other ideas?

Hello - can you post or, if confidential, send to tech@mcneel.com, along with a link back to this topic, a small (if possible) file that shows the problem?

-Pascal

Hi Pascal,

Certainly. I’ve added a part of a file that shows the problem.

I have just noticed something weird as well. The behavior is pretty random. And I tried to recreate the steps that lead to the problem and summarize what happens with steps below .

  1. When I opened the file directly by double clicking the file it shows problematic textures, like this:

image
image1803×1587 36.5 KB

  1. But if I open the file by first opening Rhino and then selecting it from the recent files in the Rhino splash screen, it shows the textures without any problem. Like this:

image
image1920×1229 134 KB

and it opens like this:

image
image1802×1590 51 KB

  1. Now when I subsequently save the file I have just opened via the splash screen and then open it again by directly clicking the file’s icon, shows the textures without any problems again. Like this:

image
image1372×1036 24.2 KB

  1. But when I add a piece of geometry (a simple mesh cube), and assign a new custom texture with a .jpg as diffuse, save it, close it and open it again, it doesn’t show any textures anymore. like this:

image
image1920×1410 56.1 KB

  1. Open it via the splash screen again and it looks fine, like this:

image
image1920×1409 95.8 KB

  1. Now when I save it and open it by directly clicking the file icon, The textures are gone again. Which was not the case when executing step 3).

  2. Another way I tried to open the file is by first opening Rhino and then open the file via File > open. It seems to open normally that way, as it does via the splash screen. But when I repeat the above steps, I get the same results.

Hopefully, the above information and the uploaded file is sufficient information to understand and troubleshoot the problem. But please let me know if there is anything else you need.

I really appreciate your help. Thanks in advance.

Hello- Thanks for the file and details - I confess I am mystified as to why you are seeing what you are - so far at least it all just works, here. But, I’ll ask a bigger brain - @brian - do you have an idea why opening a file from the splash screen would behave so differently, as outlined in the post above, from opening from Explorer?

-Pascal

Wow, I don’t really have any idea. Texture resolution is something I think @andy’s team would need to look into.
