I wiped the scene settings and started over. This time with 4px displacement, going to test with 1px again later.
Both V-Ray and Corona took around 16 sec to calculate the displacement.
Both render engines were stable!
Both render engines were laying around 7.5gb ram.
I couldn't find any subdiv option in Corona Options, have you guys removed it ?
The first Corona render with only CoronaDisplacementMod turned out very low poly, and the skin pores got stretched all over the place. Just look under and around her eyes.
The second Corona render is using MeshSmooth modifier with default settings, I noticed that CoronaDisplacementMod subdivided the mesh by itself when it was above the MeshSmooth modifier. The mesh got less ploys when I turned off the light bulb on CoronaDisplacementMod.
The result looks very good, nice round chin and nose, the stretched pore problem is gone. But the 16k micro displacement map is not showing up because of the 4px displacement.
I have included the render images from both engines (About 10min render time each).
I have also included some screenshots of the settings I used. Remember that V-rays modifier overwrites the default settings.
Good job on the last Daily build guys. Just love Corona :)
EDIT: 1px ended in complete freeze, had to force restart the pc.
were you able to render the 6000px 1px displacement with 1.1?
I haven't tried with 1.1, got the head from wikihuman a couple of days ago.
Could it be that some kind of max subdivisions bound took place in case of vray?
Is it because I can force v-ray to 8 subdivs and 0.001px that v-ray works ? The pore details are so much better this way.
