Hi all,
When importing a linked block into a model, it seems to bring across with it its own lighting/sun direction setting so when it is rendered the textures are shadowed on one side as if the sun is behind them.
The sun is switched off on the block and switching the sky on/off makes no difference.
When exploding the block, the issue is resolved, however we need to retain the items as linked blocks.
Images below show the issue. Both renderings done in the same file, same model, before and after exploding the linked block. Is there a way to instruct Rhino to override any block lighting settings during rendering?
Yes, although the issue only seems to become apparent when I rotate the blocks to something other than their initial placement, as if the somehow remember the lighting (or copy a setting from their linked location).
Hi @Micha
The blocks are NURBS and not mirrored, just imported as per their previous saved state.
Once rotated, the shading on them appears inverted, as if the object is hollow. This looks most apparent on cylinder shapes. Even does it on simple shapes with no materials applied…
This is because of a bad Flamingo nXt setting. I had a similar issue here:
I’m copying my solution here so that people have a better chance of finding it.
I got a reply from John Morse (McNeel support) a while back, saying that there’s a Flamingo nXt setting MinInstanceReferenceCount that needs to be set to 1 (the default is 3).
I don’t understand what this setting controls (and I definitely don’t get why the default is 3 when the rendering comes out correct with 1 but that’s what it is).
The setting is under Tools → Options → Advanced; type in the name of the setting to filter the list down to it and then set it to 1.
