why is this so glossy?

[Anonymous]

i am applying materials to some objects and for some reason this one object 'pool circle' is super glossy and i have no idea why. i use the same material 'pool tile' on the pool floor and walls and they are not glossy

am i missing a parameter somewhere

thanks

With the Physical Material the "Roughness" parameter controls the glossiness.  Higher roughness = less glossiness, so try cranking up the roughness toward 1.0 until you get the desired level of glossiness.

i'm still a bit confused about the whole concept of materials and rendering. i'm only interested in architectural CAD and i'm primarily interested in modeling so i can create something for both the customer and also to give to a local licensed architect/engineer to do the building permit drawings. (i realise most people start with autocad then do the 3d later, but that's not the way i work, i think in 3d, so i do that first and then have a local guy do the official autocad drawings, which are all in Thai anyhow)

however, it would be nice to do some photorealistic renders for advertising our business

so i got v-ray thinking that's the way most people go. so am i correct in thinking i should be using physical material for all my materials with v-ray? my materials are mostly jpgs of floor tiles, concrete, woods, fabrics, that kind of thing. and glass and water for the pool 

thanks

The Physical Material is fine with the Vray renderer, and also has the virtue of being compatible with the Arnold Renderer that comes with Max, should you decide at any point to switch to Arnold (since it is free with Max and Vray is a bit expensive, at least in my opinion.)   The Vray Material is obviously also an option for Vray, but I would pick 1 material while learning because the parameters differ and as a beginner you do not need the aggravation of learning 2 different sets of material parameters to achieve photorealistic rendering.  You just want a good result and I think the Physical Material will get you there and is more broadly compatible than Vray.   However, if your collaborators or clients want Vray materials or for any other reason you are committed to Vray, then that is a different matter and you can achieve very good results with the Vray material.    Once you have learned all the concepts, you will be able to learn any new material that supports physically based rendering (PBR) which I am sure you have heard of. 

Concerning Photorealistic rendering, this requires more than just plugging a texture map into the base color slot.  Base Color (sometimes called "diffuse") just provides color information.  To get photorealism, as you have already seen, you have to adjust the glossiness, reflectivity, transparency , etc, and a variety of other "real world" parameters depending on how deeply you want to get into things.   But the scene lighting is also very important to getting a good result, so you also need to learn a little about HDRI lighting (briefly you put an HDR image in a dome light and tweak exposure to light the scene.)  This gives the materials you have labored to create something more complex to reflect (vs just some lights). 

So, if your goal is to make some impressive photoreal images, I suggest you learn about both HDRI lighting with Vray and PBR materials and rendering.   To get you started, here is a link to some tutorials, in case you are not familiar enough with the search terms to use..

You can also add "architectural visualization" to the search terms; I have seen quite a few tutorials on this on the net.   Hope this helps.

great, thanks for the info

i suspected as much, i'm not very artistic, i'm a builder turned designer, so i'm thinking hire a local Thai 3d artist to tweak the materials and set up the lights. they are pretty cheap over here and can do a far better job than me.

If using the Arnold materials, must use Arnold renderer. Otherwise, everything is glossy.
