Engine 2 test

[Peter Milner]

Just started a render using Engine 2 and this is the CPU usage I get (no higher than 23%).

Is this normal?

With Path Tracer, everything maxes out

I spoke too soon.

Looks like it's picking up momentum.

I ran a test render over the weekend, saved the render in nXt format, then tweaked the nXt image and saved as a tiff with Alph channel.

In Photoshop I selected the Alpha channel and created a layer mask.

As you can see from the image this has made the whole render translucent:

I'm not sure I completely understand yet.  Is the alpha channel present in the nXtImage in places where it shouldn't be?  Use your cursor and status bar to see-- it's the fourth color channel-- or use the View menu to see the alpha channel more directly.

[Peter Milner]

You can see here that the alpha channel isn't totally black where it should be.

Is this an engine 2 test?  In any case I'll likely need to see the file to diagnose.  Haven't seen this here so far.

[Roy Hirshkowitz]

If it is e2 I'd love to see the result, regardless of potential alpha channel bug.

same issue here with the alpha channel

[Roy Hirshkowitz]

What's the issue exactly?  Is it e2 related?

[Jan Verzelen]

not sure if this is adressed to me. The problem with e2 is when saving the image with alpha channel, it's impossible to use it as mask in PS.

[Roy Hirshkowitz]

Can I get this model for testing.  I'm not seeing the alpha channel problem here in any of my test images.

[Peter Milner]

Yes, it's engine 2.

Here's the image.

If you look closely at the white storage unit, bottom left, you'll see there are still a few blotches left to resolve which is a concern considering the number of passes.

Also the top of the arms on the chairs look splotchy.

and here are the stats:

Very nice image overall-- any thoughts on how it compares to PT?
