Thank you very much for your reply!

I found it and it's indeed 2.2.

Thanks for the advice, too!!!

Hello everybody,

I posted a new topic, because I couldn't find an answer of my question - where is the setting for gamma correction? Using Sketchup Make 2013 and Vray demo downloaded from the vray website.
I'm still following the vray for SU manual and I'm on the topic for Gamma correction. So, I want to set it 2.2 as given in the manual. They say that I can find the setting in Global Switches, but maybe this is valid for an old version of the render. Now it's not there or I can not see it...I don't know.

Can yu help me please? I want to get more realistic image using Vray Sun and sky.

Many, many thanks in advance!!!

And very sorry for the very basic quest!

Thanks to all of you guys for the time you spent on my problem!!!!
I'll start over with a different texture.
I tried with a color, because I watched a tutorial like this and it seemed fast and easy to check how bump works.
Well, David,I was also thinking that the scale of the bump map itself is too small and therefore invisible.
Again, thanks a lot.

I'll tell here when I get a good bump map!

Greetings

David,
Thank you very much for your help!
I'm noticed that when I enable displacements, I get nice render, where the unevens are visible.
But when I disable it and keep only the bump option - it all render absolutely flat. I'm using the sun light and removed the rectangular light - no difference.

Probably there is a scale factor in the vray options or in the materials options, which is low for me...I don't know. The bump multiplier is 20!!! And still flat....

Thankfully the displacements "work", but I just keep wondering what is the problem with bump. I hope soon I'll find out and I'll share here.

Thanx again to all of you!!!

hi dcauldwell,

Thank you for your help!
I was thinking about point "a) ensure you have the bump map in the right place in the texture maps"....
It may be a stupid question, but is there a special folder on my pc where the texture maps and bump maps should be stored? And should they also be in the same folder? Maybe this is the main problem (excepting the light)....
And for the light...So far I can apply only rectangular light, as I'm following the manual. I'll read about the other sources of light and try it.

Thanks a lot!!!:-)

Hi valerostudio,

You bump seems perfectly well even without difuuse texture.

Please, can somebody look at the very basic model that I fastly made to try out if it wrks this time. But it doesn't. The bump file I'll atach also, as I'm not sure if you'll get it with the skp file. (I don't know how to export the whole file, including all the attached subfiles, like images etc.)

I'll be very thankful if somebody take a look and try it on his machine...Or see my mistake.

Thanks!!!

Thank you, David! I tried it with a rectangle light above the surface. It didn't work.
Is there any very important setting without which bump doesn't work, that I maybe missed? Something in the environment options or maybe the bump images file format? I tried with jpg or png...

I just noticed that I see the bump maped in the preview of the material in the Material Editor.
But when I render it, it's purely flat.

Hello,

I'm a newbie with renders, in my case - Vray.
I'm folowing now step by step the Vray manual excersises, but I'm stuck now on bumps.
I must say, I was looking in the web for an answer of my question, but I couldn't find it.
I know that the problem is in me and something that I DON'T do properly.

I'm making my trials with bricks - it didn't work. It's like the grayscale image is not added at all.
Than I decided that maybe I can not see the difference - edited the greyscale picture, making it sharper, increased the bump multiplier - all the same after endering.
Than I decided to make a test, following this tut:

It's very simple, but for me it didn't work....

So I wonder now where am I wrong.

Do you have any idea?

Thanks a lot in advance!!!

Hi all,

I see that the topic is old, but I think that I can help somebody else, who just starts with VRay for SU.
I'm a brand new newbie and I'm still busy with the manual of Vray for SU.
I also just stuck with the translucent materials - I made tousands changes in order to get the proper look of the material, but the result was - just solid opaque material.
Than I started to search the web and I found this helpful tut:

The MOST important here is that we don't needed to check the translucent checkbox! Strange, but it perfectly works! Then the result is great and what is needed!!!

mwm5053, many thanks for you reply!
The link with the sample is really very useful andit gives a good impression of all the renders.

Hello all!
I'm brand new here and brand new in rendering, but more than familiar with sketchup.
I'm creating interiors partitially in my work and I didn't render anything in SU so far.
I'll very happy if you give me a direction -which render would be best for a complete rendering beginner. And in the same way - it would be great if it is easy to use, but this is not a must. The most important is to provide great photorealistic images!
I wanted to try Twilight, but it is not developed for Mac, I think.
Is Maxwell great at photorealistic projects?

Thanks a lot in Advance!!!

Hi all!!!
I would like to join to your community!
My name is Cveti. I'm a civil engineer, but my interests are mostly in the fields of architecture and interior design.
I use SU ( the free versions) since a few years and I love it.
My new task is to learn to make a photorealistic renders of interiors, so I'm going now right to the gallery, which I hope will help me to choose the right render for a cmplete beginner.

Good luck to all of you!
