I think you need to at least understand the basic physics behind these phenomena before trying to tackle these effects.

First of all, the image you posted looks to be light coming from a projector, so the source of the light is multicoloured, it's not being split by another medium. Secondly, fog is ...

If it was as powerful, or more powerful than a Titan (or even slightly slower), at that price, no one would buy Titans anymore.

ElBloko, just wanted to let you know that when I check these forums, I always look for your name under the 'view new posts' section to see if you've posted an update to your work. It's amazing and truly inspirational.

It's buried somewhere in forum discussion. It was definitely said though.

Amazing renders, but in the last one I couldn't tell that the darker toned wall was actually on the same angle, so it really confused me that the painting didn't appear to be sitting on the wall properly. I had to check the first render to realise it was actually the same wall. Bit of a weird ...

Looks really nice. The main issue I felt was present in the first render was that the front grenade didn't 'feel' like it was actually sitting on the ground with the lack of a contact shadow, but you've nicely addressed that in your second render. Good job.

One more small critique is that in the ...

More texture blending modes for more advanced material creation would be nice.

It takes a lot of calculations for rays to pass through a whole heap of invisible geometry. It's much better to modify your leaf geometry (which I'm assuming is one quad), cut it a few times and modify the shape to as closely resemble the texture as possible. It will increase the polys of each leaf ...

I've always thought of it as orb-ex.

It's actually OR-BEX. If you want to hear it pronounced keep an eye out for GTC next week

Funnily enough, both ways read exactly the same way in my head.
