floor reflection
show user profile  zeefusion
how do I reflect an object on a black floor? I have a 100% reflective plane with an environment bg of pure black.

Because I am using HDRI maps, the floor reflects them. I only want the floor to reflect my object, not lights or HDRI/environment maps.

Normally I would fake it in PS, but its an animation. Any ideas?

Breaking physics - particularly physics relating to light - can be difficult in 3D Studio. Especially when HDRI is involved, it likes to be realistic.

If the environment was an object, I think you could just turn off the option for it to appear in reflections.
Specialty: Non-organic modelling and effects.
Setup: 3D Studio 2010 with finalRender.
Rig: No, no I can't.

You can use the material environment slot to override the hdri. In this case the floor material. that is if I get what you are saying. :)

I tried that, I added a mix material set to black in the environment slot of the 100% reflective vray material. . It works and the floor is a pure reflective black, but the reflection is very blotchy.

Does Vray not have a background / env switcher material?

Can you not just put the background mat in the env slot of the material assigned to the object?

Looks like you need more GI samples. You could also try using GI slot in override mat to fix any problems.


I am going to have to check that out, think I heard you mention it before and it sounds very useful. Cheers.

The background mat is just a diffuse black, there is no map. In a nut shell I just want the floor to reflect objects in the scene not the environment HDRI or any lights.

BishBashRoss2 - I increased the reflective subdivs and there were no improvements, My Vray render settings have always been ample enough for a good result.So I think my sample settings are fine.

I don't see you using the material specific environment map slot in that image. If I would show you but my vray dongle is at work. You can get me on msn, I can talk you through it more easily there.

Is this the slot you mean? if so then i added a mix material in there set to black. Is there a specific material i should be putting in there in order to clear up that blotchiness?

That's the one. That one will override the vray reflection map for that material. Also, you can use an override material to separate GI and reflection environment maps for instance.
