Confusing dialog when saving small

Rhino Rhino for Windows

I recently started using the SubstanceImporter Adobe plugin to use Substance materials in Rhino. Whenever I use an .sbsar material in a model, I get this warning when I try to save the file with SaveSmall:

I don’t understand this question - when I add the Substance material, I uncheck the “Embed SBSAR file” option in the Material panel, and the material that triggered this message is only 7 MB in size.

I’m not trying to embed anything in the Rhino file (it’s only 2.3 MB), so this and the material size together is still far smaller than the 96 MB in the message.

What triggers this message? Is there a way to avoid it? And if I check the “In the future do not show…” checkbox, will it default to No (as I’d prefer)?

As a suggestion, it may be better to rephrase the message because I don’t understand the source of it and the Yes / No choices aren’t terribly clear either, with respect to the checkbox. (The message is clearly related to Substance materials somehow, because it doesn’t show up in models where I don’t use any.)

By default, Rhino embeds textures into the file. I don’t know what the size threshold is for this dialog to appear. But it is related to textures and not to substance materials.

I assume the substance material has compressed textures, and that the reported size is of the uncompressed textures. If you save that file answering “yes” what size is your file going to be?

Thank you, the message being size-dependent makes sense and the model has ~25 materials right now (most from Rhino, only 1 SBSAR). When I select Yes to the message, the file jumps from 4.1 MB (I worked on the model since I posted the question) to 17.5 MB and saving takes about 10 seconds.

I knew about the texture embedding but I’ve never seen this message before; it may be helpful to clarify the verbiage.
