Progressive path tracing renders

[natty]

I certainly wouldnt use it at the moment for a first bounce but as second and saved as Lightcache i feel it adds a little something extra to me renders.. so thumbs from me.

Trapezium what do you mean by indoor/outdoor borders?

Sample Size = 0.005 (because of the indoor/ outdoor borders)

[Trapezium]

The top of the wall where the trusses hit the border of the hall and the patio area. There were problems of the light-leak sort due to the high contrast in lighting and the thickness of the upper wall. If I posted the uncorrected render you would see that the hall originally is almost black and the exterior is just about as bright as you see it now.

Hope it hasn't caused any confusion but my example you're seeing is with corrections outlined in this thread...

My first PPT

Just let PPT run on part of a current job the other day. My first time playing with it. I think it has real potential for finals. Definitely warrants more testing.


This is the PPT solution at about 2 hours:



This is IR+PPT, using saved map:

Light cache is amazing a quick test with DOF and glossy materials, 1h43min.

Bratwurst,


That was the first thing that i thought of....how much faster it is to check DOF with PPT. Just lower the samples down and you can still get a good idea how its going to look through the grain.

I know I use PPT for all my preview renders.

nice test Bratworst!
I actually like the grainy image, it give a nice film grain type effect

Bratwurst did you use a HDRI map to light the scene, and enviroment.

Bratwurst did you use a HDRI map to light the scene, and enviroment.

The test was done with a tiny part from a larger project with a bitmap environment and a simple gradient for illumination in the env. override slot. No HDR maps or lights used. The floor is slightly blue coloured glas with glossy refraction. Light cache and PPT settings to default xpt subdivs cranked up to 10000.

Cheers!

No lights? WHat about the shadows?

[s0real]

is there a difference between using a saved vrlmap from the light cache or a jpeg from the render window as pre calc'ed second bounce?

[Bratwurst]

No lights? WHat about the shadows?

Just in case your not joking. From the gradient environment map like I said.

Cheers!

I looked all over ! First bounce, second bounce...can't find it- how do I enable the new PPT option ? Apologies for the "newbie" question 1.46.15 on 3dsmax 6
