HtoA Renderer Error

[Matthew_Zinn]

Hey All,

I'm still relatvily new to Houdini and HtoA, but I love it so far 😉

I'm trying to render a scene where I use vellum to create pages turning in a magazine. I've separated each sheet of paper as its own group and then assigned each group its own Arnold material. When I try to preview this render in the Render View it stalls forever on "Generating Scene" and if I try to render a frame, I either get a black screen or the following error:

Error

I've tried this on GPU and CPU rendering, the same process (with assigning materials, etc) works fine with mantra.

Would really appreciate any help from the community on this.

Thanks so much

It's /obj/rndr_May

/obj/rndr_Mag/polygons: out-of-range shader index (2/2)

Everything in there is exported as one mesh, and shaders assigned to different sets of polygons. But somehow the map from polygon to shader has bad values.

thats really strange. Even stranger... I got it to work correctly using HtoA in Solaris just now. Thanks so much for your help

Would you be able to send us your scene so we can take a look at the error please?

[Matthew_Zinn]
