Finding some really strange behaviour in how NME materials behave with HDR environment maps right now. I think there are elements of the Babylon rendering pipeline I don’t fully understand, within which NME materials are being treated differently from PBRMaterials in a way that doesn’t make sense to…

It is fixed in the PR: Without the PR (but with the current code in the PG): [image] With the PR: [image] The difference is because in the PR the default texture type for the opaque texture is now HALF_FLOAT, whereas it is RGBA8 currently. You can fix it like this without the PR: https://pla…

Quick note: you need to add the image processing block to support exposure, etc…

That’s good to know! Are there any good examples of the image processing block in action?

Nothing specific: simply drop it at the end like that: [image]

Hmm, it’s giving me some odd behaviour. If I use a material like this one in the PG, it errors out. In my local scene it does work as a material, but doesn’t seem to be affected by exposure changes, and strongly burns colours in an odd way. Here’s the updated PG with that material: https://playgrou…

PR: NME PBR: Add full support for image processing BabylonJS:master ← Popov72:nme-pbr-fiximageprocessing opened 07:04PM - 22 Apr 21 UTC (UTC) [Popov72] Popov72 …

Thanks @Evgeni_Popov ! Is there a way currently to work around it in the NME material in this PG https://playground.babylonjs.com/#WGZLGJ#2855 using the ImageProcessing node, or do we need to wait for the new build to come through?

No, I don’t see a way to make it work in the current state, but the changes have been merged so they will be available from the next nightly build (which should be in a few hours).

It’s now available in the preview CDN / on the Playground.

Looks good on PG! Will grab and test latest npm when it’s available :slight_smile: (not sure if there’s an easy way of running preview build except running a local build?)

PR:

The PBR block already supported image processing but not fully. After the PR is merged, it will support the full image processing feature set and you won’t need a ImageProcessing block: just link the lighting output to the FragmentOutput rgb input.

How to add object with Node Material to Image Processing?
