Indigo Renderer Forum

Hi, I'm kind of a beginner in skindigo and I'm having problems with an image.
I'm using an exit portal and an IGS.
for some reason the IGS is not as strong as I'd like it to be (even if my RGB gain is up to 50) and is giving me fireflies.
Ps. Image is 1920x1200, SSF of 6, TM method is linear, and using Bidirectional with MLT and glass aceleration.
Best.

give the lamp more power (about 3x). It's all at scale is it ?

What kind of glass are your using ?

the clear glass material that comes with skindigo.
here is another jpg. it has been rendering for over 6h
any tips on how to get better quality faster?
my whites are r210g210b210, linear method and SSF 6 also using glass aceleration.

Remove the glass and see what that does. In you current scene the glass does not contribute much to the scene, e.g. you cannot see any reflections in it. removing the glass should clear up the scene quicker as it avoids unnecessary calculations.

Unless you've already done this, reduce any clean whites in your scene to 70% of the full 256, so for the RGB triplet that would be (180, 180, 180). This will also reduce calculations.

Edit: Nice scene by the way. Keep going!

Dismiss the3 glass in the window as Headroom said, then also disable Glass Aceleration, since it only helps with "flat glass meshes" and not with your glassware...

Also use ExitPortals for your windows (and other openings), check out the video how to do so here: http://www.youtube.com/playlist?list=PLD14E96A2CD263FE1

If you use LightLayers for all your lights you can easily check what light does the most noise

Thanks I'll try a new image without the glass. and reducing the whites.
that is an exit portal through the window and an .igs above the stove.
I'm thinking on putting another light in the lamp avobe the table and ideally a perforated material on the lamp shade (like a wicker texture), but I may be getting to technick there for a beginner.

Another tip would be to make the emitter meshes as big as possible, so they can be "found" easier by the rays.
Also keep the polycount as small as possible for emitters for (a little) faster rendering

what are the plycounts?

The number of polygons (triangles or quads) that your mesh has.
