Ok I don't know what I'm doing wrong here, still foolin' around with this boring scene but wanted to test it out with 0.7t5 and I am getting some pretty strange results with my water...
This is what I'm using in water:
Code: Select all
<medium>
<name>Water.scatter</name>
<precedence>10</precedence>
<basic>
<ior>1.33</ior>
<cauchy_b_coeff>0.0</cauchy_b_coeff>
<absorption_coefficient_spectrum>
<rgb>
<rgb>0.0 0.0 0.0</rgb>
</rgb>
</absorption_coefficient_spectrum>
</basic>
</medium>
<material>
<name>Water</name>
<specular>
<transparent>true</transparent>
<internal_medium_name>Water.scatter</internal_medium_name>
</specular>
</material>
Does precedence have something to do with this?

Ok, I am letting it run a bit longer, so I think it's getting better, I'll post any further problems if they come so.... still I would like to know what precedence really does....

Well, after 6 and 1/2 hours of rendering it did kinda get better, but still some strange colors in caustics, and some appear in places where I believe they shouldn't be..., I dont know what I'm doing wrong
One thing though, the rendering is much cleaner than last version (0.6)...

Hi joe
I think these caustic-fireflies (if that is the right name) will go away with time.
When bidir will be re-enabled maybe this will help in this case too. (just guessing)
An option to turn off caustics would also be great cause i think this scene dont really benfit from them.

It's just noise.. it's a little more coloured because i changed the spectral sampling code a little.

AH!!!
Ok Ono, just never seen noise like that.... I was going out of my mind changing settings trying to figure this out, now that you say it will go away with time...then, "So Be It"
Thx Ono and manitwo!
BTW: what is precedence?

Ah yes!
The manual, forgot there was an updated one, even in the indigo dir...
