Topic: [blender] Normalmap not tiling

[pazur]

I have a pretty basic question: I added a normalmap to my material but it's a.) not tiling just like the color-map b.) it's not tiling at all

Maybe I'm doing something wrong. These are the setting I have in "Map Input": http://www.screencast.com/users/ypiotr/folders/Jing/media/9a8d9c7a-7615-4c24-aac8-6d77de13b9f6

The effect of not tiling the normalmap looks like this: http://www.screencast.com/users/ypiotr/folders/Jing/media/d88e59e5-c066-464f-8acc-724c6852f960

Switch "Map Input" to "UV". Additionally, if this is something for game output you shouldn't really use/rely on any of the other 'Input' settings as it will give you a distorted impression of the end results when exported - using the "Size*" settings to 'tile' textures aren't used for games content (unless it's Blenders Game Engine), so reset those to "1.00" (and "0.00" for "ofs*") as they're not exported.

Oh and you'll also need to make sure each texture map 'channel' uses the same settings, so all of them should be set to UV etc..

This window is an object I exported from the Quake Wars SDK. I want to add more details to it and render a texture from it (maybe also include "renderbump" normals).

I figured it out btw. There is a button saying "repeat": http://www.screencast.com/users/ypiotr/folders/Jing/media/40c294e1-6970-4fbb-a926-678ec1a88554

That just affects repeat in Blender rather than on game models so you'll need to scale the UVW 'correctly' relative to the texture size as explained here. Texture scale on models is done by UVW maps.

Good to know. Thanks!

Do you think I will need to for the "renderbump" method (http://www.katsbits.com/tutorials/blender/baking-normal-maps-from-models.php) ?

[kat]

For 'renderbump', material settings don't matter as again it's all related to the UVW map - normal baking uses the UVW map as a kind of 'paint-by-numbers' area into which it paint the normalised colours. So, you need to make sure you've laid the UVW map out as best as possible.

Cool. Thanks
