material doesn't show when spotlight is used

[waverider]

spotlight completely dims the material of my model, try uncommenting the hemispheric light, the material will show up

Yeah this seems to be a bug in PBR

Tracked here: https://github.com/BabylonJS/Babylon.js/issues/3397

[GameMonetize]

Nope actually this is not a bug:)

Intensity is different with PBR:  http://doc.babylonjs.com/how_to/physically_based_rendering#light-setup

Here is the fix: https://www.babylonjs-playground.com/#11BH6Z#322

Other option would be to turn off the physical falloff: https://www.babylonjs-playground.com/#11BH6Z#323

Hey @Deltakosh, maybe you/we can talk about how to avoid this PBR lighting "goose chase" (fake-out)... next time it happens? 

I think waverider lost some hours on this one, and I would love to insert some kind of warning, somehow, so it doesn't happen again.

This is related to gltf I guess. It may not be obvious that using gltf implies using PBR which in turn requires real world light setup (or options to turn off falloff)

 

I have to admit I don't know how to do better than mentioning it in the doc (which it already the case)

*nod*.  Thx for info, DK.

Waverider, would you mind adding some tags to your post?  I think, at least... gltf, pbr, light, whatever else you can think-up.

Possibly put 'PBR' before 'material' in the topic title? (edit first post)

Perhaps give @Deltakosh permission to add some too, if he wishes?  That would be cool.  That might help others find this important topic.
