UV deformed in BJS while ok in Blender

Bugs
1

Hello folks,

So here I am working on yet another game. This time it is bigger so I have to do some UV mapping and stuff. Anyway, I designed a simple barrel in blender, and textured it, when I import it into BJS the UV’s are not quite right. I have tried with both blender 2.8 and prior. Also, both with newest BJS and prior. I have tried to increase the Max decimal precision for UV’s from the default 3 to 5, still no luck. I am attaching a couple of screenshots of blender and of the BJS result. Interesting enough, I have never had a problem like this and I have imported tens of models in BJS without any problem. Maybe it’s something I am doing but I think I checked everything.

Thanks in advance!

@Null : Hmm. Want to post a .blend file so I can take a look?

Here is a low poly barrel that I made a long time ago displayed in the sandbox - see image below.

No dreadful distortions like in your images that you posted

Hey @gryff,

Thanks for the reply, I could not seem to be able to share it here, it allows only images, but I just realized it allows zips as well. barrel.zip (630.1 KB) . Maybe it happens because of how I have unwrapped the model.

Something which might be a useful information, exporting it as an OBJ works great. However, as I will export the whole scene from blender OBJ is not an option.

@Null : TY for the file. I took a look at it and the texture does seem a little odd. See Image below.

So I did a swift creation of a barrel with my texture and my unwrapping. This zip file contains .blend file. in which I packed the texture. So try exporting from that file to .babylon. It worked fine for me.

a_barrel.zip (280.1 KB)

I don’t know why it would work with a .obj format. Don’t use that format.

As for the texture you are using, the steel bands wander all over the place. Did you make the image somehow from the unwrapping?
.
Feel free to use my .blend file.

cheers, gryff :slight_smile:

Thanks for having a look @gryff . I have made the texture in blenders texture editor. I am aware the unwrapping is not perfect, from what I noticed, the obj exported file has 6 decimal digits while babylon exporter allows up to 5. I think with meshes unwrapped such a way this causes a problem but I am not entirely sure whether this is the case or not.

Oddly enough, I have exported many models which I have unwrapped and I have never encountered this issue. Maybe I have done a more careful unwrapping :smiley: . I think this can be used as a use case to improve the blender exporter nevertheless :slight_smile:. Thank you for your time .

Cheers!

Lol this barrel is wild, this why ive avoided texture wrapping since the 90s

True! It still should work though :smiley: . I mean it is not perfect but it works for what I need it, it is definitely not read correctly babylon side.
