VScale parameter reversed

[vortice3D]

Hi Julian:

Please note that all textures appear wrong when applied because they have the VScale parameter reversed. One has to set it to -1 in order to see the textures correctly.

If scene is saved and reopened, the textures are reversed again. But putting the textures in first place without changing anything, saving the scene and reopening it, will display the texture correctly.

Best regards.

Will fix that, thanks for reporting :)

Thanks to you, Julien.

I cannot reproduce, maybe I'm trying at the wrong way. Are you exporting the editor project to reopen it (.editorproject)? Or the Babylon.js final scene (.babylon)?

Dear Julien:

Ok, let me talk to my colleage in charge of CGs, tomorrow in the morning(CET), as he's the one who told me about this weird behavior.

Best regards.

[julien-moreau]

Thanks! Then will try to fix tomorrow :)

Hi there, joie here. I don't know what you mean by "editorproject", I can't see where I can save an editor project. The issue with the VScale happens with every 3D model we try with. Although the issue is very strange because it seems to be just a visualization problem because, if I don't touch the VScale and just reopen the scene, the texture is fine.

Hi Julien:

After the last message (sent by my coworker Joie), if you still can´t reproduce the problem; I think we can test the behavior in another computer.

Please, let us know.

Best regards.

@vortice3D I unfortunately cannot reproduce, I tried to add my own texture and modify vScale. The render was the expected. I also exported the scene and reopened it: the parameter is well applied

I'm not sure to understand the process to reproduce :(

After export and before export:

Hi Julien:

First of all let us thank you for the several improvements you're doing in the editor.

About the VScale problem, please download a screen video capture from this wetransfer link.

Please note:

• the wrong behavior in TC 2'46''.
• In TC 3'06'' we reverse the VScale (-1) and then the wrong behavior is fixed;
• In TC 5'00'' we reopen the same scene and the scale factor and environment are lost;
• in TC 6'12'', after fixing the scene the texture is shown wrong again.

We think that it has first a visualization problem (with the correct data) that forces the user to think they are wrong, and so changing the data, what takes us to the beginning.

We have tested it on MS Windows platforms, FF (v57.0 64bit) and Chrome (v62.0.320.94 64bit).

Best regards.

Ok I see the bug now! I reproduced with the GLTF loader My question: are you importing .gltf (or .glb) files or .babylon files? Or another format?

For the scale factor and all other configurations, they are available in the editor project (.editorproject). More informations here: https://medium.com/babylon-js/welcome-to-the-babylon-js-editor-c08dccdcec07 at the section "Saving your project"

By "environment", you mean the scene default environment texture used by all PBR materials?

[vortice3D]

Ok Julien:

We are working with the .babylon files generated by your BJS Editor.

About "environment" we mean the one used by the PBR, but once you mention it, what is the way to update/change the other one (cubemap or so)?

Best regards.

[julien-moreau]

After checking, I cannot reproduce the vscale :( For the environment texture, I found that it is not serialized in the final .babylon scene. So I'm updating Babylon.js to serialize the environement texture :)

[julien-moreau]

I don't know if that's possible but can you share the scene you are using so I can reproduce the bug and check why it is not working as expected ?

[vortice3D]

Ok Julien:

We are working right now in order to be able to share a scene.

I'll keep in touch with you soon.

[julien-moreau]

Thank you very much !

[julien-moreau]

@vortice3D Any news ? :)

[vortice3D]

Hi Julien:

At the moment we can´t reproduce the issue on a clean basic scene.

Let us investigate a little more, but it seems to have to do with something in our scene or geometry.

I'll come back to you as soon as we have news.

Best regards.

[julien-moreau]

@vortice3D can you test this version (which is the V2) http://editor.babylonjs.com/v2/ And tell me if you still reproduce ? :) Thanks!
