Size of Reflexion and Bump Maps

[miki66]

Hi Folks !

Is there any option to change the size of a map like relfexion or bump ? i can change the size of the texture directly in sketchup but the bump and reflexion is still way to small.
Thanks for your help !

Hello,
You can experiment with the reflection or bump textures' Texture Placement > Repeat U/V parameters (e.g. setting 0.5 / 0.5 doubles the texture size).
Alternatively, you can set a material (with texture) on the front faces of an object and another material (again, needs a texture) on the back faces. You will then be able to control the front-face textures to use either the front-face or back-face mapping by setting Texture Placement > UV Channel/Set to either 1 or 2.
Last but not least, be sure to check the V-Ray UV tools: https://docs.chaosgroup.com/display/...ContextSubmenu

Kind regards,
