Material application repetitive

[maayan.raviv]

This is my model: 

And this is how the material is applied:

How do I fix it?

I tried to model with simple extrusion and with blend. same result. material is starting and stopping.

Change the size of the Image Tiling. 

...or did I misunderstand you?  🤔

[maayan.raviv]

The size is not the problem. It's applied nicely on the top, but on the sides, the material is cut in the corners and starts again. not continuous.  

BTW, it works nicely in Rhino, but not sure if there is a way to fix it here.

Are you talking about along the serrated edge?  

Love to see a screenshot of how Rhino does it.

You cannot compare with Rhino...In Revit it is not possible to project images and maps patterns on multiple surface. Hence, the image is repeatedly applied (tiled or stretched) on each of the curved surface individually

Revit don't have the ability to adjust UV Map. So it always depends on surface. For your modeling, you have multiple grove. So Revit will each apply each surface as new surface and apply start UV map for each surface. If you want organic look, you may want to check out how to apply custom UV map from external and then import them as SAT into Revit. Check the link below.

A solution is to duplicate the marble material, 4 times in my example, and adjust the offset and rotation parameters of the material map to get different starting points for each material. Then in a pseudo-random assignment (avoiding the same material in adjacent flutes), paint these materials on the fluted surface. This way you break-up the repeating "wallpaper" effect of the UV maps being the same for each material.

P.S. As a side note, when modelling in-place, you can create 4 material parameters and paint the material parameter instead of the Revit material. You can then reassign the material to the parameter rather that manually repaint if you want to change from Green marble to Black.

Hope this helps,

Sorry, what do you mean by 'paint' the material? Is there another way to assign material other then in the material properties? (I've created a family, it's not model in place)

Also, for the first option you mentioned, meaning I have to assign 4 different materials that are not repeated (not tiled)?

I might be mistaken but I think he is suggesting to randomize the material by using the paint tool on the faces of rather than assigning a material for the entire element

You can paint surfaces in the family and associate the paint with a parameter. https://youtu.be/3J5fYF2eaks

Clever workaround to randomize material on a circular surface...you might need to use more than just 4 material considering the length of the extrusion you have there

The question remains...do you really need to remodel it in Revit? If the Geometry is not required to be parametric, you can simply bring in the Rhino model into a Revit family using FBX or SAT format which technically should preserve the textures and patterns you created in Rhino
