Help needed with Vray for max blue reflective glass material

[mattiasdecoster]

Dear anyone,

 

I'm new to 3ds max and I need help rendering a reflective material.

I need to render a building that has a glass facade that is made up of blue tinted glass and blue non-translucent reflective panels. I've got all my other materials pretty ok, except for the most important one of course. I seem to be able to make the panel as reflective as I need it, but as soon as I do that, i start loosing the blue color.

 

Hopefully someone can help me/ explain me how to set this up properly.

It should look somewhat like blue reflective sunglasses.

 

I'll also add a picture from an existing building that has the same material as a facade.

 

Thank you in advance!!!

Hello,

 

Welcome to the forum. It's been a while since i posted but hopefully I can assist you. It sounds like your blue glass is okay and it's the refective panels you are struggling with? Without seeing your render, or material setups i'd hazrd a guess and suggest you try changing the reflection colour of your material to blue.... Those sunglasses have no translucency at all, so keep your refraction value black.

 

I hope that helps.

yes posting some screenshot or setting would help.

You could always put color in the reflection slot. default is black or white, but you can put any color there too.

You could also use the fog values, this one will make the glass look more "solid" or frosted, but it also help you to tint it as need, it.

If you want to go beyond you could use a V Ray coated material, with two type of materials one to give the color and other one to give more reflection. like the solarban glasses.

where is your current render?

Hey everybody,

 

thanks for the quick replies and the suggestions! I didn't post my renders, because I didn't have them at the time of writing.

I will do this now, together with my current renders.

Also it was quite busy at work, so I didn't have time to reply myself.

 

I already tried putting color in the reflection slot, but since the material has to reflect almost as a mirror, it seems to loose a lot of it's

color depending on the hdri map that I'm using. So if I use a really blue sky it will render blue (camera 7) but when I use another hdri with a lower sun, I loose all color and detail in the facade (Camera 13). So I would have liked a material like the sunglasses that would remain blue no matter the environment.

I did indeed put the refraction to black and I used fog color as a way to color my translucent glass planes (since they have thickness).

 

 

 

Since I yesterday had to show the current state of the renders to our client I now used a VraycarpaintMtl with a blue base color, 1.0 reflection and 1.0 glossiness. This seemed to keep its color better, and they kind of liked it. But what I'm noticing now is that at parts that get low lighting it gets real dark. So I think that there probably still is a better way to get to this material.

 

I will look into the suggested coated material next. It sounds great. I didn't find it yet, but a search on google brought up VrayBlendMtl, so I assume that is what you meant?

 

These are my latest renders:

 

 

Thanks for the help!

You can nail this material simply with blue in reflection color. Make it a darker blue so less light is reflected back, meaning more of the color will show, because despite how it appears in your example pics, the blue windows and the sunglasses are not 100% reflective, which would be a mirror. The blue absorbs the other colors, thus tinting lighter colors in the reflection (like the sand in the sunglass reflection).

 

For the refractive blue glass, copy the first material, then add blue to the fog color and adjust the multiplier as needed. In my experience, a little goes a long way here.

 

I don't see there being a need for complex materials and shaders with this scene. Basically, adding blue and turning down the reflectivity a bit should be enough to get you where you want to be.

 

Looking forward to seeing an update.
