roof texturing in rhino

[bkjernis]

Jim and who ever else is taking an interest. Can you please look at this blender thread and tell me if it is possible to do what I want in octane for rhino. Please see the top photograph to start. This will determine whether I purchase the octane for rhino plugin. Saramary has been trying to help me out with a problem I am having in blender3d. Thanks! http://render.otoy.com/forum/viewtopic. ... 30#p210530

I think this is more a modelling question than an Octane one - and yes, Rhino can do what you are asking for. If the roof renders the tiles correctly in Rhino - it will be the same in OctaneRender for Rhino. IMO, you would be better off using UV mapping than planar mapping - then Rhino can control the exact location of each tile.

Paul if you look at the mapping of the eyebrow dormer don't you think it is perfect enough with planar mapping. I am new to mapping. Which is easier?

It's entirely up to you which mapping you use. However in the Rhino plugin, the plugin will take the UV coordinates from the Rhino mesh generated with whatever mapping you have specified for that mesh in Rhino, so because there are UV coordinates, the Octane plugin will use UV Mapping by default. You are welcome to change the projection mapping to whatever you want, but UV mapping will be done by default, and will ensure the Octane textures are mapping identically to the Rhino render mapping.

Hi bkjernis,

The mapping in your image using planar mapping is stretched around the dormer since it's a flat projection. It's not accurate to how it would look in real life. I'd use UV mapping as well, you can get it spot on that way. On the other hand, if the camera angle you are rendering doesn't really show the "stretching" of the texture map, then you'd probably be fine to leave it that way -- it's up to you!

Thankyou Faceoff and Bendbox! Are there numerical controls in rhino for octane to adjust the size of image textures like a shingle image texture. In Blender there are no such controls that I am aware of. In Blender I had to just use the scale keyboard shortcut.(S) And then drag my mouse.

May I suggest trying the Rhino demo version - then you can see it's considerable capabilities.

I agree with Paul -- give Rhino a try. Most people who aren't sure about Rhino, give it a shot, and end up really liking it. And yes, there are numerical controls for texture mapping.
