Problem with texture tiling

RobertDy

Ok simple noobie question here...I'm enjoying applying fabric shaders to clothes products, but one texture I bought comes with 4x tiling for horizontal and vertical by default, while the clothing product's texture is 1x for horizontal and vertical. So when I applied the fabric shader as a shader preset, I have to make the tiling 1x so that the clothing product's texture will work properly (since on 4x tiling it shows up 4 times on the clothes). But in turn, this makes the texture fabric's pattern very enlarged. 

1) What should I do so that both textures can show up in their appropriate sizes?

2) How do I blend both texture maps so that their diffuse, opacity and other maps can show up seamlessly?

Thanks!

Typically, the textures included with an item of clothing are not tiled - they use one image to cover the whole surface 

Conversely, generic shaders that can be applied to any surface tend to be based on seamless tiling, so they can be repeated when/if required. The shader maker doesn't know if their work will be applied to a handkerchief or a bedsheet, so it needs to be tilable in order to scale.

So, if you want to completely replace the original surface settings with your shader, just do so and set the tiling numbers to whatever looks right, it doesn't matter if it's different to what was there originally.

If you want to keep some of the original surface images - opacity, displacement, normal, bump - but replace others, that's more tricky. I believe I've seen something somewhere that allows you to limit the tiling effect to only certain channels, but can't remember where. I tend to make brand new surface images for diffuse (and whatever else) in a graphics program, using the images from the shader as I need them.

If the material is using the Iray Uber base shader you can open the Image editor dialogue for the property (Surfaces pane Editor tab, click the micro thumbnail next to the property you want to adjust, Image editor - not Layered Iamge Editor - and adjust the tiling)

Chris - thanks, I'll try combining the original clothing and shader textures manually in Photoshop and see what I can get.

Richard - I'm not sure if I understood your comment correctly, I went to the tiling section under the Editor tab of the Surfaces pane, but the only thumbnails I could see are the gear, favorite and lock icons, none lead to an image editor...

If you click on the image, then there is an option for Image Editor.

Ah i get it now and the problem is solved! Thanks again everyone!
