How to apply 2 materials on the same wall

Rendering
21

This was working in the v8 WIP last I checked. Sub-objects can have separate mapping channels applied to use those specific settings for the object itself. v8 will also have a number of other UV mapping updates and this is a good time to take a look and provide feedback if interested.

22

Hereā€™s a v8 WIP sample file that shows the set up. The polysrf has two mapping channels, 1 and 2. The sub object face has a material applied that uses mapping channel 2 for itā€™s texture.

The development work in this area is ongoing and in looking at this post and making the sample file I uploaded, itā€™s clear we still need to change some things in the UI to make it more obvious what is happening when adjusting sub-object mapping. @theoutside and I were just discussing it and weā€™ll file some bugs/requests for @Jussi_Aaltonen . I think the number one thing is that a sub-object selection should still show a mapping section in Properties that leads you to creating a new channel.

Thank you.

Iā€™m coming to Rhino from FormZ which has a very easy click and drag Interactive texture mapping method and this has been difficult to do quickly in Rhino. Any chance you all are making any updates there as well?

Currently the Gumball is used to scale and reposition any mapping widgets and these need to be enabled in the Properties panel to do so. Iā€™ll discuss this with the developers though and see if there are any thoughts on improving these widgets and making them more obvious. Thanks for the suggestion.

Hi Brian,

Thank you for your feedback.

If there was some way to make the mapping process more intuitive that would be great. FormZ and SketchUp both do this graphically without so many unnecessary steps through menus. A Texture Mapping tool is used. So perhaps Rhino could do something like, Using the Texture Map tool, select a object or sub-object (Shift+CTRL+Click), assign a material, then pull the arrows to snap to corners to complete interactive texture mapping. Assuming your cube example, which is perfect. Thoughts?

Just following up here to see if this has been changed at all since October?

I feel subselection is sometimes not so easy to handle and so I have a wish: could it be possible that materials and mapping are kept after _join is done and transformed to subselection properties? Doeā€™s @Jussi_Aaltonen develop this?

Hi Brian,

After another year in dev, I wanted to circle back here to see if this has been updated in Rhino 8 or WIP yet? Currently, it seems that setting up multiple Mapping Channels for sub object faces, remains a lot more difficult than is really necessary on a single object like this cube. Why canā€™t we just select the sub object face and use the Texture Mapping tool there straight away? Those are the most logical steps to do this without unnecessarily exploding the cube first.

Iā€™d love to migrate to Rhino full time but this is a really big shortcoming compared to the ease of texture mapping in other applications like formZ and SketchUp. Working in 3D environment design for retail, and trade show exhibits need this feature to be quicker in the same way you all improved the Gumball to now have Push/Pull. Interactive Texture mapping is easily done in the other applications, where as Rhino feels like a programming procedure.

Hi @the.Capt ,

Iā€™ve filed that request as https://mcneel.myjetbrains.com/youtrack/issue/RH-84653

The other filed item regarding keeping materials and mapping after a Join is still open and slated for the v9 dev cycle currently. Sorry, I canā€™t give any more specifics on when this would be worked on. Iā€™ll bump the issue though again now.
