Render Time Boolean - Distance Map Issue

[dj_buckley]

See attached, I've some really complexed shapes/panels to make so was hoping this would work, but as you can see in the image, my booleans are 'hollow' is that makes sense.  I need the resulting borders to be bridged together so the red part still looks solid

The basic setup is the same as this, just without the 'inside colour' object as I want it all the same colour/material

You need to create a second CoronaDistance driven boolean set up, but this one reverses the effect and is the inverse, preserving the edges only. Those two together will give the appearance of a solid boolean.

Hmm I've just tried that but it doesn't seem to work - I assume you mean the duplicate cutter object as per the thread I linked to.

Or have I misread it, let me look again

Here's the scene, I genuinely can't get it to work so i'm clearly missing something very simple

I would try this plugin.

Thanks, but you can ignore me now.  I was being stupid.  Got it working now

And the best part is it works with Round Corners too, does life get any better than clean geometry and a render time boolean with chamfered edges? haha

[dj_buckley]

Spoke too soon - up close it doesn't work with round corners at all, why would this be?

Does it work if you make your base geometry bigger? It is normal that artifacts start popping up once you zoom in a lot.

[dj_buckley]

Thats not zoomed in as such.  That's a full res crop through a camera rendered at 5000px

Making the geometry bigger isn't an option.  These are set size panels.  I'd normally just extrude it, but the geometry is too complexed with multiple panels of varying sizes covering the entire facade of a building.

I'm now considering just making displacement maps for them all and using the water level displacement to give the impression of a solid panel
