There was a problem hiding this comment.
Thanks Eric!
I've made a few comments inline, but just small stuff.
Looking at the bigger picture, I think it's really important that this PR doesn't change behaviour for existing renderer-specific mesh lights. I reviewed pretty closely in that regard, but if you could confirm that is the intention that would be great (we likely discussed this already, but I'm a little fuzzy).
In addition to the ShaderNetworkAlgo tests, I think it would be valuable to have some image-based tests in RenderTest, that will naturally apply to all subclassed tests and give us coverage for all renderers. That'll help keep us honest in future.
I made my own little contact-sheet of various setups to compare our implementation across different renderers and to compare to RenderMan and Arnold in Hydra. I think you have something similar at your end, but I'm here's mine in case it's useful at all :

del __children
That gives me these results :
Things I noted :
- Our Arnold and RenderMan implementations are a good match. The only major deviation is when texturing the light directly.
- We're a reasonable match to HdPrman, except it illuminates from both sides of the mesh.
- hdArnold seems to be in its own world when compared to our implementation and hdPrman.
- Cycles and 3Delight seem very broken. I expect this is something I did wrong, and am hoping you can point me in the right direction.
Hopefully GitHub lets me send this - it has been very broken most of today...

apiNameToken seems misleading, since in most cases we're actually looking at a concrete schema. I think schemaName would be more appropriate (API schemas are still schemas).

That makes sense, I had thought "all schemas are APIs" rather than "all APIs (and other stuff) are schemas". Fixed in 4856cac

Performance doesn't matter here, but it's a bit odd to construct the same TfToken multiple times. For == TfToken( "MeshLightAPI" ) I think we can just compare to the string literal. And for FindAppliedAPIPrimDefinition(), we can use apiNameToken.
Alternatively, we could just use UsdLuxTokens->MeshLightAPI everywhere - maybe this is better?

NodeEditor construction is slower than we'd like. I don't see any evidence that this metadata lookup is a significant part of that, but it still seems a pity to lead with this linear search for everything.
Can we start by splitting key on :, and then only do the search when we find that the parameter name contains a prefix?

Can we achieve the same by registering metadata against light:*:arnold:*? If so, I think that would work for all USD lights, not just the mesh light.

We discussed offline leaving this as-is with an additional to-do which I've added here 28de40a.
Currently USDLight and USDMeshLight get metadata through different mechanisms, neither of which fallback on the light:shader:parameter pattern. It sounds like that's worth doing, but worthy of breaking off into its own PR.

Why would a USD mesh light be assigned as osl:light?

We wouldn't - that was a holdover from a previous iteration I missed cleaning up. Fixed in 0aa97d2
These match our current descriptions for Arnold light plugs.

One issue with your 3Delight test was easy to solve, they have one shader that uses a different name for surface emission and you happened to land on that one. That's fixed in a997611 There's a bigger concern I found though that needs more investigation. If I switch your mesh light geometry from a plane to a sphere or cube, it works as expected. Switching it back to a plane during a live render (by moving the connection in my case) helps the plane to work like a mesh light. I'm suspecting there may be something happening in 3Delight with the order of mesh intersection / visibility attributes / mesh intersection accuracy that may be causing problems with the duplicated-mesh approach. |

This is a continuation of #6970, but this PR comes from the GafferHQ repo so it can run unit tests on Arnold and RenderMan.
This adds USDMeshLight support for Arnold and RenderMan. The USD spec, in the default mode, calls for taking the mesh light color texture from the surface shader, if one exists and multiplying it with the light color. There are a couple of other simpler modes I haven't implemented yet, but I can add those in a follow-up PR.
There's also new support in this PR for visualising mesh light textures using the existing renderer-specific texture registration system.
