Some tips about why my render looks poor?

I dont use Vray, but Twilight. But these tips apply anyway.
Your model is not very realistic, so grain orientation fixed and impossibly sharp edges softened. Also put your model in a curved stage to eliminate hard shadows. And added some shine and bump to the wood.

Suggest you watch some YouTube beginner vids.
Good Luck.

Thank you, I cannot see the file till I get home, I think I got the point of the grain orientation (If you mean the texture orientation) and the sharped edges, I watched some videos for beginners last two days but I have no clear why the floor looks blue instead of white despite of the illumination I set, I maybe get this clear when I get home and I can see the file.

the Skp wont have any render settings, but has my geometry/texture changes.
PS; your model broke on me when I went 'Round corner'. Needs a complete remodel, me thinks. Just trace over the group paying extreme attention to 'xyz' And make a good simple one?

Also deleted whole bunch of entities, a sort of studio around the 'badly drawn box'. Vray?

Now thinking original image a bit 'Stinky'?
Or, does it matter which way 'textures' point? Even Wood or Feathers?

It's not a real pronect, just to show in the forum because I have same problem with everything.

Whats the reason to see it blue instead of white then?, someone knows?

I just quickly rebuilt this. Like others were saying, you need to start with a good model, radius or chamfer the edges. I also set back the dividers a smidge. That helps make things look more realistic. Keep your materials going the right way. I brought it closer to the ground and used an infinte plane with shadow catcher. I am using Thea by the way. I used a basic studio hdri and pressed play.

Mr Ib. Lookin good. Post the skp if you have changed it.

l_breault · 3 May 2019, 16:04

Here's the skp.

It doesn't have the same materials though.

@baz, @l_breault, thank you both for telling me some tips and share a .skp file with some modifications to make it look better.

I was trying to do a better design trying not to look like an idiot (the one in the post was a fast example). I tested several configurations in the render, the only way I can get a floor close to white and not to blue is using the sunlight default option and adding a dome light, I was getting crazy trying to rotate the textured, so ...

I'd like to see some vray light setup to get something like the picture from my first post.

I need a little rest after so much sketchup

This is the best I got so far:

I think I fixed the grain orientation.
I think I fixed the sharped edges.
Now the light looks not blue, but it looks still a little pink, if I try to make it more white intense, then the furniture gets overexposed (not sure about the English word).

Keep in mind most renderers use some (a lot) of post processing in Photoshop or similar after their bake their renders. With post processing you can fix things like white balance much easier than fiddling with settings via the render software.

I think you're right, using the .skp file from l_breault and using post processing from v-ray through corrections control, I can get something like this (not as good as him, but better than my first try):

l_breault · 6 May 2019, 18:19

Much better. I don't know what vray has for white balance, but that could help. I also use an all white color for a background image and that helps.
