material issues

hi, im new to unity so might be an obvious answer. im trying to make a material using something i created in photoshop. i have followed online tutorials but seem to be getting stuck, when i assign the png file i created in photoshop to a new material. in the preview window it looks right, and how i would like that to appear in my scene but once applied to a cube for example it just displays the colour used in the texture not the actual texture itself (trying to create a wooden fence. so in preview shows all the wooden groves on the fence but once applied to an object just goes to a thick colour) any help?

to summerise texture created in photoshop exported as png. imported into unity. created new material and put the png into it. in the preview window it looks how i expect it to look in my scene but when applied just goes to a solid colour.

thanks

 

My first guess would be that the model you use does not have (correct) uv coordinates. Not really a ShaderLab thing in that case.
