Hello everyone, i have just graduated on master studies of architecture. During studies i didnt have enough time to improve my rendering and visualisation. So i decided better now than never. I am modeling in AutoCad and then importing files to 3dsMax where i render in vray.

I have few questions:

1.On top is prinstcreen and bottom is targa file of render. Why is it so much brighter?

2.Wooden flooring looks blurred for some reason, diffuse map used is 8300x5000

3.Next to pool bed, you will notice something that looks like noise effect. I am using HSV Exponential color mapping.

 

Every critique and advice will be greatly appreciated.

1 - This is due to gamma correction, and not viewing your image in sRGB space. On the VRay framebuffer there is a button at the bottom to toggle an sRGB curve on and off, just hover over the buttons until you see the correct tooltip pop up.

 

It's also worth checking that you have max & vray set up for what is known as a "linear workflow", or Gamma 2.2 as it is otherwise known. There are countless tutorials on this, but this one is the one that solved it for me a long time ago; http://www.3dm3.com/articles/tutorial-linear-workflow/

 

2 - No idea, perhaps you have Bitmap Proxies turned on in the render settings dialogue. This will automatically downscale any maps over a given size, thus reducing them in quality. This is really only worth using under two circumstances;

 

- Your scene is massive and using copious amounts of RAM.

- Your PC is old, decrepit and has hardly any RAM.

 

The only other reason I can think would be that you have filtering/blur on the bitmap turned up really high.

 

3 - Which bit? The whole image has various noise problems but let's tackle one bit at a time.

i am agree with Chris MacDonald

1. unfortunately, it looks like it has already been set up to 2.2 by default.. can i do something so my render export wont be affected by sRGB?

2. filtering/blur was 1 by default. i did not turn Bitmap Proxies. i dont even know how. Im using laptop with i7 processor, 8gb RAM which should be enough for this scene.

3. just next to bed in pool, you can notice that it looks burned or smth. like tiny white dots..

2. is probably that the "1" setting you mentioned is actually a really blurry setting. In Mental Ray, I turn it down to ".1", but I've been told the less blur on your maps, the more memory it takes to render, so watch out on larger scenes.
