Quote"Ray trace everything" option in the render node. This may be useful in scenes where atmospheres and clouds can be rendered more efficiently by the adaptive ray tracer than by the micropolygon renderer. For most typical scenes, however, this option should be disabled.
Quote from: dandelO on December 16, 2009, 01:10:40 pmI'm still noticing a real difference in render time with objects in scenes, specifically internal grass clumps, since they were mentioned before. Using the micropolygon renderer is nearly twice as fast as the new ray traced objects option. Even with low AA settings. This seems to be contrary to the release notes.
QuoteMicropolygonal rendering seems to also look better, aswell. Ray tracing grassclumps seems to me like using very low quality settings in the old MP renderer. They are barely visible when raytraced. I'm confused.
QuoteP.S. I'm not complaining, not by any means, just confused. Thanks for the input and help.
Quote from: Dune on December 17, 2009, 02:48:35 amWhat was that about using bump maps/functions, TU? You mean inserting a bump map for displacement inside an object will get it bumped when ray-traced? I'll check that anyway. Some close-up trees (e.g.) would need a little roughness. I tried getting frost on grass leaves by inserting a small sized fractal (displaced), but it didn't have the result I hoped for, although it did roughen the white.---Dune
