Exporting textures to .OBJ

Hello. First of all, I am quite new to Rhino. I am exporting a model to .OBJ to upload and view it after online on an In Company 3D viewer. (Version: 5 SR9 64-bit)

My problem is maintaining the scale of the textures I have introduced in the model when I export to .OBJ. Here you can see the model. I’ve multiplied the texture x9 to get the right size. This is what I am not certain is correct, do I have to modify the texture in some other way so the exported file maintains the scale I see in the Rhino view?


These are the Export Options I am using:


The models uploads correctly but with the original 1:1 sizing of the textures, as you can see on the following olnie viewer:


I’ve tried many things but I think I am missing something. Many thanks in advance.

You’ll need to assign a texture mapping method other than the default of ‘surface’. Then adjust your tiling of the texture in Object Properties>Texture Mapping not in the Rhino material itself. Here’s an obj and the corresponding mtl file of what I get after this process. I used Box mapping and then adjusted the mapping widget in Rhino to control the mapping on the sides of the seat prior to Export.

Thanks! Finally I used Box mapping multiplying the tiling x13 in the Texture Mapping. Thankfully the final model doesn’t need much detail and I don’t have to modify de rounded edges and the inclined surfaces.

For more complex objects I’ll try to follow this tutorial: http://docs.mcneel.com/rhino/5/help/en-us/properties/texturemapping.htm Is there any others I could use?

One last thing, as you can see the .OBJ uploads correctly aplying a x13 XYZ ratio on both pieces of the couch but in the Rhino View the density of the back piece is higher (due to the size of the object I suppose). Is there any way to see the same tiling distribution without modifying the size properties of the texture?


Thanks again.

I made this one which might help too… Texture mapping in Rhino 5 for Windows on Vimeo

Select both the back and seat and then assign a Box mapping method for both at once. They’ll share the tile settings via object props.
