Laser-beam simulaton made in Brazil. How in VRay ?

[DaForce]

SNAP... was just about to post the same thing... LOL... except i worked out the direct light and square lense myself

[DaForce]

Hey, can you post your file... i think i broke something and it just aint working right anymore.

THanks

Da main idea is to stretch direct or spot in z axis

[DaForce]

damn it... i cant get it around the last 2 mirrors, it stops on the third last.
Scaling on the Z axis makes no difference, other than lowering the quality of the beam due wasting lots of caustic subdivs. And lowering or raisin ght target points makes a difference but i just cant get past the 3rd last mirror... bloody weird.
I have a nice strong beam, and it hits that mirror and dies.

[Paul Oblomov]

Yep... only few photons get to the last lens . . . I'm working on it

edit

Increase the glass max refl. depth. For ex. to 12

[DaForce]

But see RErender's last example. he gets them going all the way around...sure they are getting pretty thing by then but still.
My beam is much more solid than his all the way up to the last mirror then just kaput, so i dont think its a photon problem. Well not in my case anyway.

So here it is

Enjoy !

Weird upon opening the file. The lights were pointing to the left and not usefull to create the laserbeams...weird...just moved them back and all is fine.

I noticed you re-created then lenses. Could you not get the original ones to work?

[Paul Oblomov]

This is kinda original Brazil scene. Directional lights are linked to dummy and moving with it Frame #250 - all is straightened...

About lenses - well didn't give much attention to 'em.

[DaForce]

....O.....M.....F......G.....
im an idiot.

So im sitting here right... thinking why the feck does it just stop on that fourth mirror. the beam is nice and strong... plenty of light... i have tried all different light positions.....
And then it happened... i swear i heard a penny drop.

4 mirrors equals how many bounces? 5... well guess who didnt change the depth of the mirror material!!! FFS i had it almost perfect from the very beginning. HAHAHAHA

Ahh well its been a long 11 hour work day and im zonked.
So i changed the depth to 10 and it render perfectly.

I love it how when the 3 beams converge the beam goes white... pretty cool.

Well if you once again read my "poem" - you'll see that...... I increased to 12 bounces

[DaForce]

hehe yeah as it turned out I never saw your edit. Hence my problems

However i have been tinkering and made something kind cool
4 direct lights and just the right angle

[RErender]

nice one, Daforce

Hehe, I was going to post the bounce thing but I thought it'd be more fun to let you figure it out. :P

[DaForce]

hahahaha thaaaaaaanks
it was definitly one of "those" afternoons.

[Paul Oblomov]

nice one, Daforce

Indeed it's a great idea
