My 1st Vray Render
-
Hi all, this is my first attempt...and I know its not great, I was hoping you geniuses could give me some tips on making this image better.
Another thing ... Is it possible to do animations using Vray for SU?
-
Graduate,
For a first vray render I would say it is quite good. What version are you running? Some tips would be:
The lights in the shower could be a bit brighter.
The material on the toilet should have more shine.
I would guess the rectangle on the front of the shower is light from a window. Try to move that so that it falls more at an angle to represent light from a window better.
Use the architectural glass (can be downloaded from Vray's site) for the glass shower door. It will give a better representation of true glass.
Overall the scene just needs more light.The biggest thing with any render is taking the time to set up good materials. This is the most time consuming part but makes a good render a great render. Using the material studio from Vray (standalone app) can really help in making custom materials. It is fairly straight forward and works just like the material editor in Vray for SU.
Good render for your first attempt. Looking forward to seeing more.

1st of all thanks for your quick response, I appreciate it.
Ive made the lights in the shower brighter,
Ive made the toilet have more shine.
The rectangle on the front of the shower which you thought was a window is a VRay rectangular light. As this is a en suite bathroom which has no windows I thought the only way I could get light into the image was to delete a wall and shine a light into the space... Is there an easier way to light interiors up with no natural light source?Ive tried downloading the 'architectural glass' from the vray site but the link must be broke as it wont download.
The material editor is a great tool Im building a libary of materials as we speak.Ill play around with my image and post the results when Ive achieved something.
Thanks again. -
Ok I took your advice and this is the result...
I used the Architectural glass as you suggested.
Why does the shower area look so pixelated? or 'noisey' ?
-
Can you send me the file and I will take a look at it?
Scott
-
which file do you mean?
-
this is a link to the skp file ... i hope this is what u ment?
-
I got the file and I will mess with it tonight and email back in the morning.
-
That would be great thanks!
By the way please be highly critical I need to learn.
-
go to image sampler and click sub pixel clamping
-
I dont seem to have a 'sub pixel clamping' option, heres a screen shot...
Any ideas?
-
Graduate,
Sub pixel clamping is under "Color mapping". This helps to keep things from burning out or getting overly bright.
I looked at your file last night and I have a few things:
Update your version of Vray to the most current as the changed the way materials are handled. It is far better not to mention a load of bug fixes have been taken care of.
I noticed you have the room open at one end. I typically close all my geometry or rooms. It makes it easier to get a real idea of how the lighting will turn out instead of using the GI coming into the room from it being open. Another good practice is to make sure your geometry is solid and not just planes coming together. If a model is built that way you are likely to have "light leaks". Build your model but then box it in with geometry to make your walls and ceiling have a thickness. This will eliminate light leaks.
Try using a physical camera. It will give you far more control over your final image.
The sink and toilet are obviously imported CAD models and do not render well. You will see that the curved surfaces tend to look faceted and not smooth as they should be. There are good model sites for quality Skethup content (FormFonts being one of them). This again, will help the overall quality of the final output render.
Make sure you purge you model regularly. There are a load of materials in your model that are not tied to any geometry and this makes it hard when editing materials in Vray to know what material goes with what geometry.
Try to stay away from using an emissive material for general lights. I only use emissive materials for things light a TV or computer screen. Using emissive materials can take render times through the roof so use them sparingly.Lighting:
There is really no reason to make your lights double sided in the way you are using them. This is a calculation that Vray does not need to spend time making as it will not affect your scene other than extending render times.
Make sure you use the check box "store with Irradiance map" on your lights. This will help since Vray does not have to recalculate the lights with every pass if geometry or the scene has not changed.Hopefully this gives you a start. Feel free to let me know if you have more questions and I will try to help out. There are quite a few people here who know Vray very well also and they will chime in I am sure also.

Stupid question but... How do you find out which version of Vray you have? And how do you update it?
-
Thanks a lot for all your help, after a bit more playing around this is what I have come up with... I know it could probably be a lot better but Im happy with it for a 1st attempt and so is the client!
My next work is an exterior... ill post up my finished work.
Thanks again -
Hey those are really nice. I like the reflection on the porcelein.
-
In the render options dialog box there is an "about" section. That will tell you what version you are running. To update, go to the vray site and login with the same log in you used to purchase Vray with. Then go to downloads. If you bought somewhere else you will need to have your serial number ready before they will send you a link to a download. They have tightened the licensing since there were so many pirated copies out there.

What is the floor material on the last 2 renderings? It looks like asphalt... or maybe it's just my screen. They also look really 'sharp' as if you didn't use anti-aliasing to give it a softer appearance...
