Hi,
We are looking into moving our rendering pipeline to karma, generally everything is going well. We have been debating scene scales, animation is coming from Maya and is 1 unit = 1 cm, which is written to our root USD file. Based on other forum threads I understand that Solaris/Karma ignores this apart from a few UI bits and pieces, and we can just work in solaris in Maya's scale, any FXs can be scaled up and sublayer/referenced into the stage.
Unfortunately I've been getting some shadow artefact while working at the larger scale. If I covert our scene root to and xform a scale it down to 1 unit = 1 m, the artefact goes away.
It's particularly noticeable with geo that are quite low poly, I've attached a screenshot of a basic bit of ground that's shows the problem when using a dome light.
Coming from VRay, lights there have a shadow bias setting, which is the control I would go to for this kind of artefact. Does Karma have any kind of control or a global scene scale option?
Thanks David,
Karma scene scale
