Hello everyone,

I am trying to make an OSL to work in Object Space instead of Screen Space or raster. The code looks like this


Although this code works well in 3ds Max for example, for some reason in Houdini doesn't work at all. My OSL knowledge is quite limited, so I am not sure how I could fix this. Any suggestions or ideas?

Hello everyone,

I am trying to make an OSL to work in Object Space instead of Screen Space or raster. The code looks like this

shader GetObjSpace
(
    point Input = P,
    output point UVW = 0.0
)
{
    UVW = transform("object", Input);
}

Although this code works well in 3ds Max for example, for some reason in Houdini doesn't work at all. My OSL knowledge is quite limited, so I am not sure how I could fix this. Any suggestions or ideas?

What renderer are you using? Renderman? Arnold?

Arnold. Seems like a bug to me. After some testing and more testing, I think there is an issue with the scale. Sometimes works, sometimes doesn't. I reported to the Arnold team as I am not sure if this is an issue from Houdini or Arnold.
