Is this a regression recently?
I recall in Houdini 20.0.590 with HtoA 6.2.5.2 to be able to do camera shader projections - however one had to manually disable some of the default expressions the materials would make in LOP material networks because it'd always assume you want geometry level objects but I believe specifying actually USD prim paths did work fine in our renders at the time?
Issue synced internally to ARNOLD-15174
Hi, it looks like the projection is working fine, however the Arnold Camera Projection houdini node is taking an operator for its camera value instead of a stage path. The aspect ratio also seems wrong at a first glance.
It is using the classic htoa way of selecting cameras, we need to translate somehow the operator path to the stage path. I moved this ticket to HTOA: HTOA-2635
The aspect ratio also seems wrong at a first glance.
Ah yes, that's correct - we removed the expression and just entered the valid USD path. So it's mostly "cosmetic" on the Houdini side - the actual render translation logic does work.
Basically:
Describe the bug In the Solaris viewport, the camera projection shader always uses the render camera. An exported USD file has the wrong camera name for the projection shader ("/stage/projection_camera" instead of "/cameras/projection_camera"). An HDARNOLD_DEBUG_SCENE ass file has no an empty camera_projection.camera parameter.
