Hey Guys ,
I received a bike model from a client, that is missing some textures. And im struggling to get the right texture on the back reflector…I need a something like this
However to make it look right, you’d need a normal or displacement map version. I have had a look and can’t see any candidates online, so it may be something you’ll need to model, then bake a map from the model.
You would apply this to the rear faces of the model.
you can just combine Diffuse with Glossy. First make the image perpendicular with an image editor, also create a normal or height map to give it a bit of bumps:
Thanks guys for the input, this will definately help. And no, no closeups for now but those might be requested later… Ill try this solution first and if it doesnt work, Ill know where to find you
thanks again
A normal map won’t cut it, as a retro reflector makes several internal bounces and a normal map only bounces directly out. You either need displacement mapping or actual geometry to make it proper. For far away shots, a mask using geometry/incoming to drive glossy normal will do (like for retro reflective tape).
With proper, I mean actually retro reflect. Normal maps may be fine to fake the appearance, but it won’t reflect a viewer light source back to the viewer no matter the angle.
I was talking about to simulate the texture of the rear face.
From the way the OP framed the question, it sounded to me like the OP wanted the item to look like a reflector, but not to act as an actual retroreflector.
Yes that is true… for now…I just need it to look like an reflector…not act like one since is just for a product visualization.
But i might need to make a close up animation too, and then It might be usefull to make it act like an reflector too. So ill now how to achieve that too because of you guys. thanks!
Then if you give it a suitable material, like a simple glossy with a roughness of 0.1, it will act like a retroreflector if your lights and camera are in the correct orientation:
