New Build (305)

[Roy Hirshkowitz]

Mostly more work on e4.  There were some reports of trace instability with the previous build.  Let me know if this build seems stable.

to update to the new biuld do I just reinstall the program?

 

does it change any of the works in progress?

Just install the new build. The process uninstall the former build and installs the new one. It does no changes to work in progress.

If it's a specific drawing, send it.  Otherwise there isn't much I can do.

[Roy Hirshkowitz]

Try a very simple model with simple materials.  If all of your models contain displacements this is likely the culprit.

[Roy Hirshkowitz]

Last time I checked, the bathroom one appeared to run with displacements-- just very slowly.  I need to check to see if there's some problem or if it's just a characteristic of the engine.  My models with displacements run just fine with this engine.  Not sure what's going on with yours.  The displacements in the bathroom scene were very finely tesselated, minimally displaced, and viewed very closely.  Any single one of these factors could be contributing.

Same model, same view, different engines. Some contour problems where model meets background image.

[Roy Hirshkowitz]

e4 right?  Background edge is a problem I just fixed (I think)-- other artifacts are caustics which should resolve after a bit more (I think.)  If you suspect something is wrong send the model and I'll take a look.  Note the small stem wall behind the arched canopy-- those lines are caustics (I think.)

Sorry Roy, image file names contain all information - passes, engine, time etc.

[Roy Hirshkowitz]

Ah-- what does 305 mean?

[Roy Hirshkowitz]

Never mind-- brain problem.

[Roy Hirshkowitz]

I'm considering making reflective caustics optional for e4, probably a material editor switch.  Refractive caustics would still happen automatically.  The net effect of this is that the reflective noise we're seeing due to shiny surfaces would go away (unless you ask for it.)  Swimming pools, glassware, etc. would still exhibit caustics.
