There seems to be a problem with ground planes… I assign a material from the library to the ground plane (I used Product design -> Cast iron) -> open Render properties -> click any of the tree dropdowns (for instance 360 environment) -> the ground plane unchecks itself in the ground plane panel. If I check “Show Ground Plane” -> “Use a material” I get the default material and not the one I previously assigned. Clicking the material dropdown causes the “Show Ground Plane”-checkmark to dissappear again… So I have to click “Show Ground Plane” -> “Use a material” again.
@jdhill: I also noticed that pressing the IPR settings when rendering with Bella IPR in the viewport also causes the ground plane to dissappear / uncheck itself.
Before I install the version you are using to check this, could you please quickly check how these things work when you use raytraced, with rhino as current renderer? Reason for asking, I think this is not related to the plugin’s code, and I have not noticed it here, so it may also be mac-specific.
For what it may be worth I just now recalled, I remember seeing something maybe similar to this on a v7 build, maybe 2 builds ago, on windows. In that case (in bella, not sure about cycles), the ground plane might disappear, or might be set at the wrong elevation, and it could be fixed, at least temporarily, by moving some object to force an update. However I am not sure if this corresponded to the ground plane checkbox actually being toggled in the gui, or if it was just different data being communicated to the plugin, and I do not recall having seen it in probably the last 2 wip builds.
Hasn’t happened since (had the same problem I V6, by the way). It can take some time though - especially with a new model. Hmm… I wonder if that has something to do with the materials having to be downloaded first?
I had Bella as the default renderer. Switching to Rhino render doesn’t seem to make a difference. Sometimes the delay is only (?) 5 seconds, but just a moment ago I had the beachball spinning for about 30 seconds…
