Any Suggestions on how to improve my vray renders?

[Roca]

Hey

I've only started using vray recently and this is one of my first real attempts at creating some serious renderings. The attached rendering is still being developed and I'll update this thread when the project is done. I was wondering if anyone had any suggestions on how to improve my lighting or textures?

Thanks

Carlos - I'm afraid not many people can ... Material and light are living from reflection and refrection. A render without environment can not give me a way to make you improve. So even if I say that the concrete doesn't seem to have depth in it and appears flat with out bump map could be wrong or right. RK

Thanks for the reply. I'm going to try and finish the last bits of modelling so I can focus on texture and lighting.

In the mean time I have a few questions. Would it help if I applied an HDRI map or should I actually model the environment? Also do you know of any reasons why my texture is mapped so strangely? Do you have any tips or guidelines for mapping textures on the geometry like mine?

Thanks again.

Well Carlos - : your mapping of material has to be like in real live. Have a look on concrete buildings and how they are made and even better learn about construction mode - it helps than building it in 3D. Your maps are to big - just for example - at a distance like that you shouldn't even notice the detail structure of concrete..... I woud combine HDRI with some more modeling - otherwise with only HDRI just use for the whole project PS. ( kidding ) RK

Thanks again for the reply. I understand how the concrete should look but have trouble translating that into the UVW settings. I've just finished modeling the storefront and just have to fill all the windows above with glass. I've changed the texturemapping to box and changed the repetition. I still feel like something is missing from the concrete. Any ideas? I'll try it again with an HDRI in a few mins when I locate one.

Thanks again Ralf

Even in that case I would use unwrap mode so you can devide the concrete zones how in reality does happen , and not a whole box uvw, tiling buildings which in reality are never tiled regolary - but u'r getting closer and closer and closer ........

This is just an update. I took a few steps back and rethought the texture. I'm not rendering with Vraysun or Sky for now. I might try to add it in later.

Is there anyway to get a higher resolution on the textures? The texture itself is very detailed, but that doesn't seem to show up on renders...Would output resolution do that or is it in other settings?

hello
Why don't you render with vray sun sky and physical camera, it's not that hard.

just create a vray sun , answer yes to automatically add a vray sky to the environment,

create a vray physical camera (leave everything at default change only
white balance to daylight and shutter speed to 400 to start with).

In the Customize > Preferences > Gamma and LUT tab do the changes as in the attached image.

Enable Vray frame buffer

In the image sampler rollout chose adaptive DMC as the image sampler type and VRaySincFilter as the antialiasing filter.

You can leave the adaptive dmc sampler at default values to start with

in the color mapping rollout chose Linear multiply (this is my choice, but you can also choose Reinhard) and change gamma to 2.2 and check affect background, and eventually sub-pixel mapping.


There ! you are good to go.
