Shadow feature and MAX TEXTURE IMAGE UNITS limitation

[lesydat]

Can you fix light through walls when turn on light?

[adizanni]

Hello, starting from recent release, the problem has been fixed by setting the shadow parameter to 'yes'.
Note that the shadow feature is very greedy in PC resources so you may want to see if this is applicable to your model based on the complexity. Also be aware that, at today, the activation of shadow may have some collateral effect on the lights. To workaround the issue I now give the possibility to set the vertical alignment of the light inside the bound object. This gives the possibility to make a light appear in the case it is shaded by the light object itself.
Please try it and let me know if it works for you.

Turn on shadow make my home model can't load. I use Firefox and my laptop only has Intel graphic

I suspect your problem is similar to the following #36.
Can you please activate the logs and paste here the console content here ? This can be achieved by opening the Web Developer Tools in the Firefox menu

Hello lesydat, please post here the snapshot of the screen you will find here https://browserleaks.com/webgl or here https://webglreport.com/?v=1
This shows the limits you have on your browser related to the number of supported THREE.js (WebGL) objects.

So, before I see how to optimize the usage of lights and shadows, you will not be able to put more than 16 (Max Texture Image Unit in your WebGL report) lights into your model. I keep it open for further investigations

Added a new task in project 2.0 to see how to handle lights to consume less GPU resources. Closing the issue as the behaviour of the card is according to THREE.js and WebGL limitation

Sorry for my late reply (I come from issue #36). I also confirm that with the shadow set to 'no' the 3D model appears normal. I also attach my WebGL browser check just for reference.

Yes geolos, and do you confirm that you had more than 16 lights defined ?

[geolos]

Yes I confirm that the lights were more than 16 (and with shadow set to yes there was a problem). When I reduced them the model appeared ok. In both cases the model remained the same; with the same number of textures.
