reflections

[celmar]

hello! i have a red plate, very reflective, but as it is a plate, it has no readable reflections; putting a lamp, it reflects, but it's a bit "poor"...; is there a way to introduce an image in the shader, only to create a more complex reflection? i tried in the ior channel, but it doesn't give anything... thanks for your suggestions!!!

Why not just have an HDRI in the scene, so there is in fact something to reflect? If you need a solid color background in the render, you can always add a solid color in the environment overrides for Direct Visibility.

PS - you can override how an object looks in reflections using the RaySwitcher, but you can't override what an object reflects. Also the IOR slot is for mapping the IOR amount, e.g. for a dirty surface some areas will have a higher IOR (white in the map) than other areas (darker in the map), it doesn't affect what is reflected.

Not sure how in C4D, but at least in 3ds Max, Corona materials have an option to override refractive and reflective rays, so you can have different backgrounds per material.

^True, in Render settings are options to control Scene environment

I'm not talking about global override in render settings, but about override per material. On the other hand this could be one more thing that is still lacking in C4D implementation...

Yep, those aren't there in the C4D implementation (that I am aware of), hence the global override approach.
