Lightmaps question

[Freelance3D]

yesterday i installed the new 1.46.05 version and tried lightmaps for the first time.

i thought that lightmaps are faster then QMC but when i render the same scene with lightmaps it takes longer.

irradiance map for first bounce + qmc for second = 11800 seconds

irradicance map for first bounce + lightmap for second = 13600 seconds


i have a ground plane with displacement and most objects are glossy metal objects.

irradiance map was on high settings and lightmaps are on default settings, only disabled store direct lights.

In my experience Lightmap's do take longer when Displacment is involved....why i dont know .. ? take the displacment off and see what happens.

ok will look how the difference is without displacement.

another problem i noticed is, that max freezes for 10 minutes when i chancel a rendering.

first i thought that vray has crashed max but then i let the system alone for some time and as i go back max was there again.

that is very annoying!

yea .... this is known ...

The freeze seems mostly due to releasing the memory when doing a displacement
