Vray For Sketchup

Portugal881

Hi Guys!

I got a problem with 'flat' vray render, what I mean it's not a quality render. I have quickly render a chair, that does not shows it's details when rendered...

I am new to vray , and using 30days trial version.

I also rendered that chair using podium v2, it's better but still not the render I am looking for.

Anyways I want to render using vray, I know I probably would have to change some settings, but no idea which!

I don't need breth taking render but still would like to have some qulity in it.

Would really appriciate if you could give me some suggestions!

I have attached 3 images, to show you what i mean

rendered by vray, it do not show chair details like material texture and shape of the chair

this render is by usnig podium v2, the render ist not perfect and I didn't change anything, but still you can notice some details shown on the chair- which vray doesn't shows

and that is just and image imported form sketchup, to show you the details in chair before render

Are the faces on the chair reversed?

that must be a light chair since it is floating.

Thanks for replay

I am not quite sure about the faces?? I only imported that chair form sketchup warehouse, and didn't change anything. I 'opened' the chair group and took and image, if that will help you with something? : see below

hhaha I just noticed chair is in 'air' At first was wondering what you meant by it , well I created that view only for this post, but normally working on a bigger model about 55kb.

I would be very glad if you would give some suggestions what I can do to sharpen up and make that chair looked more detail.. Why is that happening.

ps. I have attached 2 images of the model I am working on, so you can see the problem and also the other issues.

![Thtat is a rendered view (one of the first i did with vray) of the model I am currently working on.. I got some issues with it as well:

i feel it's quite flat again
the stained glass panels doesn't show the colour reflection on the floor](/uploads/imported_attachments/DonV_1.jpg "Thtat is a rendered view (one of the first i did with vray) of the model I am currently working on.. I got some issues with it as well:

![This is another v-ray render . I was trying to figure out lighting seetings.. and night mood.. it didin't work. Not quite sure how to change te size of light, set up the dirrection and etc. But I assume you busy , so didn't wanted to ask all this questions, since I can find the answer with trying and trying.

The only thing I know I won't be able to figure out that with with a chair - Why it doesn't show any sharpnes and detail to it?

Is it me, or the render in overall is kind of not sharp? If you know what i mean by it...](/uploads/imported_attachments/7rAZ_3.jpg "This is another v-ray render .

The chair itself has a very dark material which means the only way to show detail in it would be with proper lighting. In a real world example, if it was that sunny outside and you were looking at a black (charcoal) chair in such harsh, bright sunlight you probably wouldn't notice any detail in it either.

My suggestion would be to play with either the material of the chair (lighter color perhaps), or turn off the sun and use Vray lights to achieve the perfect amount of lighting to bring out the details in the chair material.

Try playing with chair material in vray material editor, if it is material from sketch up it will have only extracted bitmap of texture, try adding some reflection, maybe even bump map to it, which is also good for some other materials, like wood so that it doesn't look flat, and you can lighten material via Photoshop, gimp or some similar software. Also about light, for daylight, u can change camera settings in vray options editor, allow camera to catch more light, change strength of sun, softness of shadows ( that is controlled through size of sun ) etc...
For night settings you could use vray spot lights to produce light from, ehm.. spot lights u have on the ceiling and make that yellow material that is in hanging lamps emissive.
Basically, when rendering with vray, a lot of things should be done through its material and options editor for quality of final product. Hope that it helps a little .

All materials reflect in real life. Add a reflection layer to the material and a bump if it's textured. It it's leather, download a leather material from Chaos website.

Thank you for all the helpful suggestions. Gonna try them in a minute ! Hope it will work

Valerostudio, could you pass me link to that chaos website.. was trying to find it in googole but couldn't find anything with textures?

Here ya go http://www.chaosgroup.com/en/2/index.html Great materials here. I find it crazy how many paid Vray customers don't use all the resources given to them. Hope you have a field day with all the free materials.

Holmes1977 Thank you for the link, - no wonder why I couldn' find the textures on their website.. I am still not a official vray customer, As i just started to testing demo verison so would need to manage with some textures from google images

But thanks anyway, good to know about some great web for the future

Oh and by the way, I am stillllll working on the model, but will need to start doing my render soon.

I was watching few tutorials for rendering with vray for skp, and was trying the settings they showed on the tutorials.. some of the render took about 9 hours , 4 hours , some of them an 1 h or 2.. since I don't really know much about those settings. i am just doing what they are showing on the videos

So, to fasten up the future renders I was thinking of coping my model and open few the same sketchup models at once and then render on every model different scene. Would you think that would make vray to render longer? Or it would actually safe me the time of renders ? ( that's what I am hoping for .

Ps. You guys, are so nice! I can't belive there are some many people that are willing to help and give advise in a cost of their time!

Just increase the gamma value of the image which is applied to the chair.
Take new Standard material in the V-ray Material window.
Then in the diffuse panel, click on the options button which will be indicated by "m".
And then click on the none (selection option).
then select "TexBitmap" from the dropdown options.
On the right panel under section BitmapBuffer. select the image Image you want to apply.
And then under the file option you will see the gamma option.
just change it with the variation of satisfy result.
