Adaptive subdivision

Post by Sharlybg » Sun Apr 19, 2020 5:33 pm

As the title say it is about adaptive subdivision issue when using displacement feature in Luxcore. The current issue come from the simplify node. While trying to resurect an old project put in Hold before displacement i encounter Very very huuuuge start up time for my rnedering It become extremelly wilde with the simplify node.

finally the time lost before render start make me just render the project with full geometry on the Cpu where with adaptivity that would be possibe on the GPU.
i have pretty small gravel so original geometry need between 6 or 7 subdivision to show good quality. To reduce pression on the engine i just paint part of the geometry that are not visible with a simple matte shader with no displace on it.
