How do I reliably save photo textures used for meshes directly into the .3dm file with the model, not in a separate “sidecar” folder? These are textures from photogrammetry with a unique texture for each mesh. I need to be able to move the .3dm files, including on a different computer, open the .3dm…

Hi David - [image] David Cockey: How do I reliably save photo textures used for meshes directly into the .3dm file with the model, not in a separate “sidecar” folder? I’m not sure what a “sidecar” folder is but it sounds like you are running into a reliability issue. Can you post a 3dm file…

@wim My question revolves around the _embedded_files folder which Rhino creates, sometimes. That is what I was referring to as a “sidecar” folder. (“Sidecar” is a common term in the photo editing world for added files or folders which are created during processing and need to accompany the file wit…

i think you have to use the advanced setting Renderer Development Kit.Settings.RendererSupport.AlwaysUnpackEmbeddedFilesToTemp setting it to false should stop that from happening.

Hi David - [image] David Cockey: Setting does not exist in current WIP V9. The only “render” advanced settings I see in the current WIP V9: Thanks. It looks like those have gone into hiding again. I’ve reopened the following: → RH-84241 RDK settings don’t show up in the advanced Options pa…

[image] Wim Dekeyser: As long as the advanced NeverEmbedFiles option is not changed from the default False, Rhino will always create self contained files. @wim Thanks for the explanation. I had previously searched the Advanced options and did not see anything relevant. NeverEmbedFiles is Fal…

Hi David - [image] David Cockey: It seems like NeverEmbedFiles is True on my WIP V9 installations, not the default False. That doesn’t rhyme with this part, though: [image] David Cockey: Then I transfered the file to another computer and opened it. Rhino created an _embedded_files folde…

[image] Wim Dekeyser: If your image files are getting put into a folder when opening on a different system, they are being embedded into the Rhino 3dm file. I probably opened the file using V9 rather than V8 and that caused the _embedded_files folder to be created. [image] Wim Dekeyser: A…

[image] David Cockey: I probably opened the file using V9 rather than V8 and that caused the _embedded_files folder to be created. I’m confused about the problem now. For opening a file, the setting of NeverEmbedFiles is completely irrelevant. The embedding (or not) happens when saving a fil…

Even if image texture files are embedded Rhino will extract them to disk upon opening of 3dm. Either in a folder in %TMP%, or in the embedded_files folder next to the 3dm file. Rhino needs that to be able to actually use the textures.
