Feature Request

Would it be possible to have an optional feature added to Rhino that allows for backfaces to have a pattern on them rather than just a colour?

I often use various colours when modelling (as garish as it can be) to help me differentiate parts and give them specific meanings. But, when I add coloured backfaces, sometimes the colour is so similar to the colours I have in use that I can’t tell the difference.

What would stand out would be the option to have something like a mid-light light grey dots or hatching that would stand out from colouring.

Thanks.

Hello - the only not very graceful workaround that comes to mind is to apply a 2 sided material and set the object to use Rendered or a copy of rendered mode (SetObjectDisplayMode):

Hi, you can setup a custom backfaces material per display mode, which may include some patterned texture. I am not sure though if the size of pattern will stay consistent on all geometry, since they will have various UV coords. But maybe you could experiment with that.

I have been doing that for several years. Here are my favorite backface patterns:

Pascal, Thanks much for the quick reply. Aye, that does look slightly less than graceful but not a bad consideration for some other things. I did have a play and it wasn’t quite as efficient as I was looking for. Jaerk and Andrew’s solutions worked great. I clearly must’ve missed the custom settings when I was looking at this - just what I needed

Cheers, Jarek. I hadn’t noticed the custome option before somehow, despite it being right in front of my face when I went back.

Nice solutions Andrew, those patterns are even better than what I had in mind. There’s no mistaking that they’re backfaces, until I start texturing coral, that is! Mind if I steal these to use?

I use a custom viewsport mode to quickly check the face direction. It has yellow and blue materials, so it’s basically impossible to make a mistake which side of a surface is which colour. Here is it if anyone wants to try it.
