    Hi, so I’m basically trying to eventually port over works done in Sketchfab, to use this platform instead – I’m just wondering if its possible to do any lighting tweaks to more closely resemble what Sketchfab is able to achieve – here’s a few images from both:

    The first image is Verge, and the second Sketchfab – both are lit with the same HDRI image with no other lights e.t.c. Sketchfab and Verge are both based on Three.js right? there seems to be a lot more contrast, especially with hard shadows in Sketchfab – Verge kind of looks a little washed out, there actually doesn’t seem to be any shadows at all.

    Any ideas as to whats causing this? I tried different export settings for shadows e.t.c, and no change.

    You can add direct light to the scene with shadows, or bake shadows and AO to the texture and apply it in the material.

    I applied a directional light and it doesn’t seem to affect my scene – I created a new Maya test scene and it worked – so it seems my scene is corrupt.

    Nevermind I’m dumb, there’s a button along the top of the viewport called “shadows”, apparently turning that off turns shadows on and allows a directional light to work :wacko:

    Hmmmm, still doesn’t seem to be working when I export my gltf file. #

    EDIT: Ok so, when I sneak peak, my lighting looks like this

    But my exported scene looks like this :

    Seems to only use the dome light, not the directional & point light I put in the scene, this would explain some lighting difficulties I had before – any ideas?

    I’m not deep in knowing Maya. What all this materials means? And what the type of the material is that?

    Hmmm, are you using Maya 2020? I’m using standard surface shaders so I think you need Maya 2020 to see the materials.

    Seems thats there’s some logic issue, if I open pure gltf file it’s the same as in Maya. Seems you change lighting somewhere in the scene after load with puzzles.

    Hi, I have no lighting change (I did try create environment puzzle to switch hdr but I disabled and then deleted the puzzle, also I had this problem before I tried that).

    Would you mind taking a quick look? I can’t see any lighting puzzle in my project.

    can it be that some files failed to load? are there any errors in the browser console?

    No errors, I have upload my project and linked PM’d it to facebook, I’m having trouble with changing the preloader .css too…I feel like I have some missing files/corrupt project but I have no idea why :scratch:

    The problem caused by update_tub procedure here:

    If you delete it all will be ok.
    Can’t sy anything about css because I don’t know what you doing. More explanation will be helpflull.

    Hi, wow I’m so dumb! I was hiding all objects with my update tub procedure to single out models, but when I added the lights at a later date I forgot to add the show puzzle afterwards.

    Thanks so much! not sure if I would have figured that out myself, good work!
