I was playing with material panel and I discovered what seems a strange behavior of the internal rendering engine.
I have a scene with a lot of grass (particles fur with jahka’s new system) and an object with an Emit value (from material>shader panel) different from zero.
If I starts rendering it take 2h 10m at a resolution of 960x480 pixels.:mad:
When I reset to zero the Emit value of that material, same scene require 10m to render, with same settings and resolution!!! :eek:
I’d understand that incredible slow render process if I had enabled Radiosity rendering that takes in account the emitting value of the material for the compute of the overall brightness in the scene, but I can’t understand why the rendering process is so slow without radiosity…
