As soon as it is possible ��

Hi blanchg,
The script crashes if an object/mesh name has a for filenames non authorized character in it like #/\* etc.

[blanchg]

Hi matali, do you have a .blend or the console output? I can't reproduce this.

[blanchg]

v6.0.15 fixes this thanks!

v6.0.15 fixes this thanks!

Thank you,
most cases are fixed, but "|" (vertical bar) is still a problem. To ensure nobody else encounter the problem, there is a list of character for path here: https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

Strange the regex I am using in V6.0.15 is [^a-zA-Z0-9]. Have you updated to the latest version as your filename seems to include - as well.

[povmaniaco]

Hi blanchg.
Try to use 'clean_name' from bpy.path like

filename = clean_name(filename)

Greetings..

Thanks, that is essentially what I do but to make it compatible with Corona I need to do some extra work. I have tested with pipe (|) and it is replaced by _

what is proper way to use textures? when i load textures in texture tab,it is not avlbl in material(without using nodes)1.add new mat to obj2.in texture tab load a tex(rename diff_coltex)3.in mat click T button in diffuse channel -rollout is empty.two more issues - even if nodes are not used if blend file is saved and reopened nodes are re-enabled.i attach texture to mat with renderer Blender selected,change to Corona and reassign the mat+texture,now delete the object, exporter gives error saying deleted object's texture is missing.This is in win8 with Blender2.78c corona addon v6.0.11

[blanchg]

I prefer to use nodes, with 6.x there was a large change to how materials were handled. Looks like some things with non node materials has broken. I will have a look soon.

Give v6.0.16 a go

Yes, I updated to latest version again to be sure. I'll try to make a simplified version and upload it.

Ok, I tried the latest version and the error has changed, now I get:

The directory is writable. I can't provide the file becaues of copyright

purge orphan data
check for/if any unassigned materials or such are left over

I had no orphan data, but removing all objects on hiden layers and other scenes resolves the problem. So maybe one of the hidden object was the problem, but to find which is nearly impossible (more than 2 thousands). Would it be possible to only export visible data?

[blanchg]

I can fix the error you are seeing but I don't think only exporting visible data is what most would want. Hiding objects is a crucial part of at least my modeling workflow and I want the objects exported during modelling.

[matali]

Hi blanchg,
why would you like to export objects that won't be rendered? If they are hidden to the viewport but not for render, of course they should be rendered. But for not visible layers and non-active scene, what is the usage? If you have a fix for the 2, it's awesome

[burnin]

Am against rendering only visible data. Basic, most common example are lights, often times invisible but do influence, light the scene.

Also, what is wrong with having a clean scene file, keep irrelevant data in second & append if/when needed?

Ok, misunderstanding, I meant hiden objects, when you click on the camera in outliner for example, A good example of this are all the objects only used for booleans, which are now a lot with addons like Decalmachine or hardops. Often, you also don't want to render some of the layers. Objects that are only on those layers shouldn't be exported. And their are bugs that make some objects undeletable in 2.79 and it seems it won't be fixed. https://developer.blender.org/T51903
Of course, objects not in the field of view but marked as visible for final render should be exported.
