Help in Porcelain

[Paraglobal]

Hi all

Can someone share some environment that uses Porcelain?

I read this tutorial done with V-ray for max but I can't even get close to this quality.
Is it my lack of know-how ?

here it is the original done with V-ray:

I have done a first test and my scene is very booring:


Thanks

Re: Help in Porcelain

I looked through the tutorial, and followed a link or two. Basically I found myself to the Light Probes gallery http://gl.ict.usc.edu/Data/HighResProbes/ Maybe you can find an hdr from there, or search the internet for free hdrs. There are many out there, some better than others.

As far as why your rendering seems flat or booring as you say is due to three things, and I don't believe its your lack of know how (I've seen your images and they are quite good). The first would be environment, and a good hdr would help to liven up the image allot. The second would be the materials themselves. Presently all you've got is a white porcelain on a white plane. Give the materials some variance and play them off of each other. It will allow the scene to interact more and make it less static. The third and last thing would be to work with the composition of the image. Right now you've got everything smack dab in the middle of the frame, all bunched together, with nothing happening in the foreground or background. Play with the position of the camera, the position of the objects, pull things towards the background/foreground. Make the image more interesting by giving the image much more context to itself, right now its more like an island.

With that tutorial there is a hell of allot going on that is not explained, so don't fault yourself for not knowing whats going on with it. There are numerous important things that just get jumped over. Its as if the person just wanted an excuse to post their image, there really isn't any explanation for many key points that it would need to be explained in order for the tutorial to be successful. It doesn't even have a objective other than to tell you how the image was made, and it was only 4 steps out of 150 it seems. Most vray tutorials are pretty good, but this one falls way short.

Re: Help in Porcelain

hello sergio, these white in white or black in black renderings are always difficult to bring alive... :
what i see from my humble position: try to color the lights, e.g. the GI blueish, add a rectangular light with a contrasting color, this will give you a shadow direction too and position your porcelain in space. place the rec light to have interesting shadows, give your volumes more plasticity by modeling them with light and shadow... duplicate or even triple your porcelain reflection layers. how about a reflection of your objects on the floor, give the floor a slight reflection layer... interesting could also be to give the floor a fadeout effect with the help of an alphamap, so it melts with the sky... backroundimage with more or less multiplier could really bring things alive, but you will see the reflections in the floor too, I don't know how to avoid this, could look ugly... does anyone know a trick? are composingflags for the floor/background or object-lightning/reflecting restrictions planned/in work?

The new R4 beta support material based environment maps. Also it is possible to set independent maps for reflection/refraction/background/GI.
