USD Rendering AOVs to separate files

Hi,

 

I'm trying to render aovs as separate files in Houdini. Rendering aovs as channels of a single exr file works fine.

 

I'm first exporting my usd stage to disk. This usd contains multiple render products, each of the render product define a filename for the exr files. When I 'kick' that usd file, only one exr file is written to disk. It seems kick only sees the first renderproduct and ignores the other ones. I would have expected kick to process every renderproduct.

 

Here's an excerpt of the usd file :

        def RenderProduct "renderproduct"
        {
            custom string arnold:driver = "driver_exr"
            rel orderedVars = </Render/Products/Vars/direct>
            token productName.timeSamples = {
                1: "//server01/shared2/projects/Xavier_RD_2024/scenes/Test/Test001/FX/work/Test001_donatUSDexport_v001.renderproduct_edit2.MyDirect.0001.exr",
            }
            token productType = "raster"
            int2 resolution = (1920, 1080)
        }

        def RenderProduct "renderproduct2"
        {
            custom string arnold:driver = "driver_exr"
            rel orderedVars = </Render/Products/Vars/specular_direct>
            token productName.timeSamples = {
                1: "//server01/shared2/projects/Xavier_RD_2024/scenes/Test/Test001/FX/work/Test001_donatUSDexport_v001.renderproduct_edit3.MySpec.0001.exr",
            }

 

Regards

Thanks Stephen. My issue was that only one of my render products was referenced in the render settings
