Hello, i am trying to map a texture i made in photoshop and use as jpeg file on rhino 7. When i move the texture in mapping tool its resolution drops too much. I didnt have that kind of problem in rhino 6 but in rhino 7, it doesnt work or i couldnt make it work. I am attaching pictures to illustrate the problem.
This is how it looks before clicking apply on mapping interface.
You are indeed right, @karakusc! I wonder if anyone knows the reason why? I was never much of a texture-wiz and have no idea if this is expected behaviour or not…

But… If the mapping channel on the material is set to 2, the texture doesn’t show up in Raytraced, only rendered viewmode… @nathanletwory - I know Cycles is your domain. Can you shed some light on what’s going on here.
TIA, Jakob
I don’t know about the uv editor in this case, @Jussi_Aaltonen can tell about that more.
Probably somehow related to usage of ATP (Advanced Texture Preview), or lack of usage of ATP. I generally don’t worry too much about it, I’ll just handle the data that’s handed to me in Raytraced (:
After you click Apply on the UVEditor that object will have so called custom object mapping
Surface, polysurface and SubD objects that have custom object mapping use Advanced texture preview in order to preview the mapping correctly. Advanced texture preview uses texture baking which in many cases lowers the texture resolution seen on the object.
If your object has only one mapping channel and you define a texture to use channel other than 1 then the result will be undefined and depends on the display mode or renderer. In this case it appears that Advanced texture preview gets disabled for that object because the mapping channel 2 assigned for the texture does not exist. I encourage to avoid that trick because it may break your model in any future Rhino update.
I suggest you try one of these:
Apply your texture using cylindrical mapping
Add your ornament to the object using a cylindrically projected decal
If neither of the above work turn Advanced texture preview off temporarily from the display mode settings. Remember to turn it back on or you may experience other more severe texturing issues with other models.
Hello, thank you very much for responds and advices bu i couldnt understand what i am suppose to do with that one " 1. Add your ornament to the object using a cylindrically projected decal"
By “cylindrically projected” I meant the cylindrical mapping style for the decal. It is useful to add a vertical guide line in the center of the bowl to make it easier to pick the start and end of the cylinder.
@karakusc Hi, wanted to let you (and others too) know that texture quality in Rendered and Raytraced display mode has been improved for Unwrapped polysurfaces in Rhino WIP. Please, if you have a change to test and you find issues let me!
