"Dirty rendering"


Hans-Olav

Recommended Posts

While I'm not an expoert in RW, this looks like a global illumination issue, and a light bounce issue. Undersampling secondary bounces.

First thing to check is that there's no "light leaks" in the model, and the geometry all touches nicely, but then up your levels for "Indirect Lighting" and "Environment Lighting". Raising the Bounces / Max Reflections might help too.

Can you post a screen grab of your current RW options?

Hans what settings did you finally use.    ?

p2 interior-ny-2 is the top most picture

@Phil hunt 

I was also tweaking the textures. the curtain is different between the two rendering 

the top most is just plain transparency 

the other one uses a image map for transparency

Note how his reflections are set to 6, this is WAY higher than I have recommended in the past since it doesnt affect the reflectivity appearance all that much beyond 3. Its looking more and more that this option is also controlling how many times light is allowed to reflect, which is supposed to be also controlled by indirect bounces, or at least thats what I had thought. I'm going to be confirming and filing for separate control of this for more efficient renderings.

It would be really helpful to get some clarification from the engineers about this....
