Hi, I’d like to know if there are anybody who can explain how to increase the rendering speed.
So, after that I prepare the scene, I let calculate the Irradiance map:
Irradiance map parameters: HIGH
Hsph sub: 50
Interp. samples: 20
Secondary bounces:
Direct computation
Subdivis:10
Depht:1
I check the autosave and render.
Finally I hava a irradiance map of 30 mb…but when I start the real redering my pc realize it in the same time of irradiance map+ rendering time.
I cannot see any incrase…
Do I need to use a global photon map as secondary bounces???
What can I do???
The final image is abuot 1800*1200.
Please post me a guide step by step to set the parameter of save map…
Thanks.
P.S. Sory, sorry, sorry, sprry for my terrible english…
maybe stupid, but I miss:
“load from file”
after you’ve saved it, in the steps you descripe?
/B
Tonight I set the resolution to 1700*1200 and then I calculated the Irradiance and the global photon map. I saved them.
So I check “From File” on Advanced Irraidance and select the map
I check also “From File” on Global Photon map.
But when I start the rendering I see also the prepass.
Why???
If I use Cornell Box file, on a rsolution of 500*500, I cannot see any prepass after I’ve calculated the irradiance and photon map???
Do i set a wrong resolution???
maybe you are using interpolated glossies ?! Check it out, they produce prepasses even with precalculated irr.maps
Where can I found this option???
it’s under your material that has relfections glossies…under the refelc tions color swathc and glossiness spinner…
it’s a tick box…make sure it’s unched and set your sudvs. to about 8 or 10…maybe higher if the reflections look grainy…

Great!!!
But What kind of glass may I use???
I don’t want to see any prepass after I’ve calculated the irradiance and global map.
May I use a phong mat with 20 of trasparency and a VrayMap for reflection on 40???
What kind of resolution do I set for a irradiance map if the final image is 1800*1200???
I don’t want to see any prepass…
I change all Interplated glossy mat…
I’ve only 2 standard material with VrayMap as Reflection…
